Sir,

In accordance with section 33(1) of the Australian Capital Territory Electricity Supply Act 1962, I have pleasure in subm itting the tw enty-first A nnual R eport and Financial S tatem ents of the A .C .T . Electricity A uthority for the year ended 30 Ju n e 1984.

T he year w itnessed a re tu rn to m oderate growth in electricity dem and. Sales and purchase quantities increased by aro u n d 5 per cent. You will recall th at last y e a r’s A nnual R ep o rt included com m itm ent to:

• freeze tariffs to at least A ugust 1984, • acquit $4.8 m illion o f m atu rin g loans from internal funds, • enhance the C u sto m er A dvisory Service by im plem enting H om e Energy A udits,

• establish a T a riff E qualisation R eserve.

T hose com m itm ents have been honoured and you will further recall an announcem ent in April 1984 of an extension of the tariff freeze to Ja n u a ry 1985. G iven continued stability in the cost of bulk energy from the Electricity

C om m ission of New S outh W ales, the A uthority rem ains confident that tariff increases w ithin the foreseeable future will be m oderate in im pact. A fter an initial m ixed reception, bi-m onthly dom estic billing appears to have gained acceptance. T aking account of consum er reaction, the Authority examined

suggestions for m onthly billing as an aid to the customer in budgetting. To afford m axim um flexibility to the consum er, an optional C redit Paym ent Plan was introduced. It has to date been received enthusiastically. D u rin g the year the A uthority engaged a firm of m anagem ent consultants to carry out a com prehensive review of m anagem ent practices and procedures,

and to recom m end changes w here appropriate. Virtually all organisations within the A ustralian electricity supply industry have been subject to some form of external review in recent tim es. At the tim e of preparation of this report the final draft of the consultants’ findings was not available, however informal advice

concerning conclusions has been encouraging. T he organisation shares with you, and your Departm ent, the loss of the services of M r Bill L aw rence as the d epartm ental representative on the A uthority. Bill spent over nine years as an A uthority m em ber before his retirem ent this year.

H is ju d g m en t, knowledge and abiding interest in the developm ent of C an b erra provided an invaluable contribution to the direction of the A uthority.

W .E . Bolton Chairman

ENGINEERING

D istrib u tion System

T he distribution system was extended d u rin g 1983-84 by the installation of:

• 24.6 km of 11 kV overhead m ains • 14.7 km of low voltage overhead m ains • 27.0 km of 11 kV u n d erg ro u n d m ains • 18.7 km of low voltage u n d erg ro u n d m ains • 20 pole substations • 40 padm ount/kiosk substations

Augmentation T he total load for fixed electrical heating installed in dom estic dwellings during 1983-84 was 17 009 kilowatts, down 15 per cent on the previous year. T his produced a m arked decline in requirem ents for augm entation of the 1 lk V distribution system and enabled the A uthority to catch up on a five-year backlog of work. F u tu re augm entation will be undertaken at a reduced rate.

Suburban Development Extension to the distribution system for new suburbs continued in Fadden, C hisholm and R ichardson and was com pleted in

M ac arth u r. W ork has started for M cK ellar and the N orth Stirling areas. A ccelerating land release will require the A uthority to have new supply available in m ore locations at the same time and will require careful co-ordination with the various developers, both the National Capital Development Commission and others developing large n um bers of blocks.

Design o f sub transmission lines.

Townhouse Development T h e in-fill housing strategy results in tow nhouse and group housing developm ent in m any areas and will require careful co-ordination to allow builders and developers timely supply. These areas are generally supplied by u n d erg ro u n d services and builders seeking phased connection present a

problem of access th ro u g h the rest of the site where the developers’ works are still in progress.

Chamber Substations N ew m ulti-transform er cham ber substations on custom er prem ises were com m issioned d u rin g 1983-84 at:

Increased com m ercial load dem ands necessitated augm entation of cham ber substations at:

• C S IR O C om p u tin g C en tre — A cton • C S IR O Pye L ab o rato ry — A cton • G arem a Place — C ity

Woden Zone Substation C onnection of the third 132/1 lkV transform er to the system network was scheduled for w inter 1984, however, disruptions caused by industrial bans and equipm ent access lim itations (due to high loads) have not allowed this target date to be m et.

T he tran sfo rm er is now expected to be com m issioned and connected to the 132/1 lk V netw ork by sum m er 1984.

Causeway Zone Substation This project consists of two sites, a 132kV switchyard and a 1 3 2 /llk V Zone S ubstation site — the two sites being interconnected by 132kV u n d erg ro u n d cable with a route length of around 1000 m etres. T h e sw itchyard equipm ent foundations and control building have been com pleted, and electrical equipm ent fitting-out operations have com m enced.

C onstruction operations on the transform er yard will com m ence early in 1984-85 with erection of electrical plant and equipm ent program m ed. It is expected that the project will be completed for the later part of the 1985-86 year.

Distribution System Refurbishment A specific program has been developed for inspection m aintenance or replacem ent of the A u th o rity ’s system assets, particularly in the older areas. W ork has been carried out in Griffith and T u rn e r and will proceed into other areas.

Rural System Following successful negotiations with the neighbouring Southern T ablelands C ounty C ouncil, supply to the Bulls H ead/B rindabella valley area west of C a n b e rra was taken over by the C ouncil after 22 years of supply from the A .C .T . system. In the interim the C ouncil’s m ains had extended close enough to allow connection to that load, thereby allowing disconnection of a long rural line which frequently suffered dam age d u rin g wind and snow storm s. T h e cost of m ain tain in g and repairing the line was out of proportion to the revenue

resulting.

Project P lan nin g

Gilmore Zone Substation. A D raft Environm ental Im pact Statem ent was published in M arch covering this Zone S ubstation an d associated subtransm ission lines from W anniassa and the C ausew ay. T h e final Im pact Statem ent and a

corresponding subm ission to the Public W orks C om m ittee will be com pleted early in the new financial year. D etailed design has now com m enced, and it is planned for com pletion in 1986.

132 k V line maintenance inspection.

132kV Subtransmission System T h e A u th o rity ’s System P lan n in g Branch has revised its S ubtransm ission developm ent plans following a m ajor review by the N C D C o f its L and D evelopm ent P rogram . T his concentrated on accelerated grow th of a m ore lim ited area of T u g g eran o n g than had been originally

envisaged, followed by early developm ent of G ungahlin. W ith the G ilm ore site selected, fu rth er line routes and substation sites are being investigated in conjunction w ith the N C D C , in both T u g g eran o n g an d G ungahlin.

System O peration

Disturbances D am age or failure in some part of the subtransm ission distribution system resulted in 521 interruptions to electricity supply of greater duration than one m inute d u rin g the year 1983-84. T he interru p tio n s w ere as follows:

• O ne group of Civic Z one for 15 m inutes on the m o rn in g of 26 J a n u a ry 1984. • Fifty-one affecting one 1 lk V feeder with an average restoration tim e of 36 m inutes. • 469 affecting one or m ore low voltage fuses at a distribution centre with an

average restoration tim e of 46 m inutes in the u rb a n area.

O n the following occasions, w idespread failure and dam age to the 1 lk V and 415/240 volt distribution systems occurred d u rin g severe wind and lightning storm s: 8 and 9 N ovem ber and 10 D ecem ber 1983, 25 and 26 Ja n u a ry , 7

F ebruary and 20 M arch 1984. O n m any o f these occasions, trees fouled or fell onto lines.

System Control Room T he C ontrol R oom has been tem porarily relocated pending the installation of a duplicate air conditioning system , uninterruptible power supply and secure fire-rated room s for the new duplicated system control com puter. T h e oppo rtu n ity is also being taken to install an A utom atic Call D irection facility to increase the effectiveness of the C ontrol R oom telephone

system in handling the large n u m b e r of calls received during storm s or other system disruptions causing m ajor loss of supply.

R ecoverable Works T h e A uthority perform s work for governm ent departm ents, statutory authorities and instrum entalities w ithin the A .C .T . T h e work covers general electrical

m aintenance, u nderground supply and the relocation of distribution plant. The A uthority installs streetlighting on behalf of the N C D C and m aintains it for the D ep artm en t of T errito ries and Local G overnm ent. T h e value of recoverable work totalled $11.5 m illion during 1983-84, an

increase of $930 000 over the previous year. T he N C D C was the largest single client, paying $4.2 m illion for recoverable work in 1983-84, an increase of $200 000 on the previous year.

Streetlighting T he A uthority designs, installs and m aintains all the streetlighting in the A .C .T . on behalf of other organisations. T he expenditure on new

streetlighting construction d u rin g 1983-84 was $1 932 370 com pared to $1 757 449 for the previous year. T he funds for this work were provided

predom inantly by the National Capital Development Commission and, to a lesser extent, by the D epartm ent of H ousing and Construction, the A ustralian National U niversity an d private developers. T he w ork involved the installation of 2025 new lights and the rem oval of 865 existing lights, resulting in a net increase of 1160 and bringing the total n u m b er of streetlights on the system to 45 831. Some 174 separate streetlighting construction jobs were approved during 1983-84 ranging in value from only $200 up to $264 000. T he m ajority of these jobs involved traffic route lighting and m inor streetlighting, but a nu m b er of other projects were com pleted involving pedestrian crossing floodlighting, security lighting, sports oval floodlighting, interior building lighting, building and statue

floodlighting and num erous relocations and alterations. T h e total m aintenance expenditure funded by the D epartm ent of T erritories and Local G overnm ent during 1983-84 was $1 215 968, com pared to $858 707 for the previous year. A m ajor com ponent of the m aintenance expenditure was

7

replacem ent o r rep air o f 151 accident-dam aged colum ns com pared with 149 for the previous year. W e continue to use ‘Slip B ase’ colum ns for all new traffic route lighting and as a standard replacem ent for accident dam aged colum ns, the use of w hich has u ndoubtedly already saved a n u m b er of lives. T h e year

also saw the introduction of streetlighting night patrols, which has effectively reduced the average n u m b er of streetlights out each night from some 400 down to approxim ately 125. A nother m ajor developm ent during the 1983-84 year was the publication by the N C D C , in consultation with the Streetlighting Branch of this A uthority, of th eir ‘Public L ig h tin g ’ booklet as part of the Guidelines on Engineering and Environmental Practices series.

Underground Mains W here, for aesthetic reasons, the A uthority is requested by a developer to u n d erg ro u n d distribution m ains, the work is und ertak en on paym ent of all costs additional to those of providing an overhead supply. T he expenditure recovered for this type of w ork in 1983-84 was $3.0 m illion,

com pared w ith $2.4 m illion the previous year. T hese funds were provided by the N C D C , the D e p artm en t of H ousing and C onstruction, the A ustralian N ational U niversity an d private developers.

Mains Relocation T he A uthority recovers costs associated with the relocation of distrib u tio n m ains req u ired by plan n in g changes or building developm ents. Such costs in 1983-84 totalled $131 397 com pared with $159 562 in the previous year.

Installation Inspections Section 14 of the Electricity O rdinance 1971 requires all new electrical installations and alterations to existing installations to be tested and passed by the A uthority before connection to the distribution system. A total of 10 230 inspections w ere carried out by C ustom ers B ranch in 1983-84, 2378 being new installations, of which 1806 were for new dwellings. Included in the new commercial installations were R adford College, two motels, four major buildings at the A D FA com plex and four high-rise office blocks.

No fatal electric shocks occurred, how ever thirty-six cases of reported electric shock were investigated. C auses were;

A DMINISTRATION

Staffing

Staff of the A uthority are em ployed u n d er section 20(2) of the A .C .T . Electricity Supply Act 1962. T e rm s and conditions of service are as determ ined by the A uthority, subject to the approval of the Public Service Board. As at 30 J u n e 1984, the A uthority’s workforce num bered 818 and was dispersed

in the following groups:

E ngineering and technical 136

Finance and adm inistration 186

In d u strial 496

D u rin g the year forty-nine salaried staff and tw enty-nine wages staff left the A u th o rity ’s em ploym ent resulting in a general labour tu rn o v er rate of 9.5 per cent dispersed as follows:

E ngineering and technical 6.6%

Finance and adm inistration 21.5%

Industrial 5.8%

T he A uthority continues to experience difficulty in the recruitm ent and retention of qualified staff, particularly in its Finance and A dm inistration areas.

O ccupational H ealth and Safety

D u rin g the year the A uthority reviewed its approach to accident prevention in light of governm ent policy. T h e structure of safety com m ittees was changed

fundam entally to provide for substantially increased employee representation and participation. All m em bers of com m ittees took p art in train in g courses conducted by both the A uthority an d the T rad e U nion T ra in in g A uthority. W hile this was the first full year in which the A u th o rity ’s revised Accident

P revention P rogram operated, it was pleasing to note that the Injury Frequency R ate has been reduced from a figure of 75.6 which applied before adoption of the program to 74.3 for 1983-84.

In du strial R elations

T he A uthority allocated additional staff to industrial relations work d u rin g the year. R egular Industrial R elations C onsultative C om m ittee m eetings were held at which employee representatives and m anagem ent staff exchanged inform ation on work practice m atters and discussed issues of m utual interest. M atters in dispute continued to be processed through formal dispute settlem ent procedures. Less than 400 m an hours were lost through industrial disputes for the year. V arious bans and work lim itations w ere applied d u rin g the year with m inim al

im pact upon consum ers.

T rain in g and D evelopm en t

T he A uthority in 1983-84 decided to give greater attention to staff developm ent and training. External training courses continued to be supported but there was

Instruction in system computerisation.

a significant increase in the use of in-house training. A nu m b er of employees were train ed in group instruction skills w ith the result that basic skills training was increased. It is planned to develop this tren d in the com ing year.

E qual E m p loym en t O pp ortun ity

T ow ard the end of the year the A uthority decided to develop an Equal

E m ploym ent O p p o rtu n ity M an ag em en t Plan w ith a view to im proving

opportunities for w om en, m igrants, A boriginals, and the handicapped. After detailed exam ination o f its workforce profile, the A uthority expects d u rin g the next year to be in a position to develop strategies for provision of increased opportunities for disadvantaged groups.

A pprentices

A t 30 J u n e 1984 the A u th o rity had thirty-six apprentices indentured; nine com pleted apprenticeships d u rin g the year.

Freedom o f Inform ation

D uring the year four requests for inform ation under the Freedom of Inform ation Act were received. O n e of those requests, which concerned the H all/S utton bushfires of 1979, was partially refused u n d er sections 41, 42 and 43 of the Act. No fees w ere collected.

T ra in in g of staff in freedom of inform ation m atters continued with a num ber of officers atten d in g courses conducted by the A ttorney G en eral’s D epartm ent and the C a n b e rra College of A dvanced Education.

C ustom er A d visory Services

T h e C u sto m er A dvisory Service provided inform ation and advice to m ore than 5200 custom ers d u rin g the year on efficient use of electricity and appliances. W hile inquiries covered a wide range of issues, particular interest was shown in off-peak pow er for hot w ater and heating.

Account inquiries investigated by Advisory Staff num bered 665, of which more th an 200 req u ired visits by advisory officers to custom ers’ hom es or business premises. Five hundred and fifty requests for H om e Energy Audits were received.

T heft o f E lectricity An increasing n u m b er of instances of apparent interference with, or bypassing of, electricity m eters has been encountered. In conjunction with the A ustralian Federal Police these cases are being pursued, and will commence to appear before

the C ourts in the 1984-85 financial year. Specific m anpow er resources are to

be applied to identification of incorrectly recorded consum ption, to ensure that the practice is, as far as possible, elim inated. Some publicity has already been given to the A uthority’s concern and proposed action in this m atter.

M anagem ent R eview

D u rin g the year the A uthority invited six established m anagem ent consultant firms to subm it proposals for a review of m anagem ent practices and procedures. P. A. M anagem ent C onsultants w ere ultim ately com m issioned to carry out the review. A final report was not due by the end of the financial year, but interim reports were encouraging in term s of the A u th o rity ’s past perform ance, and included useful suggestions for steps to be taken to m eet future dem ands on the organisation.

E lectricity H ouse

A fter discovery of m aterials containing a proportion of asbestos, the A uthority arranged a com plete exam ination of Electricity H ouse to be conducted by the D epartm ent of H ousing and C onstruction. T he results of the survey have been referred to the A .C .T . Asbestos A dvisory C om m ittee. C ontinuous m onitoring has been carried out to ensure a safe w orking environm ent, and some removal work has been conducted. F u rth er rem edial action will be taken in consultation with the Asbestos A dvisory C om m ittee and the D epartm ent of H ousing and C onstruction.

C redit P aym ent Plan

In recognition of the difficulty that some consumers find in budgetting for periodic electricity bills, the A uthority m oved to provide a totally optional facility for those who wished to m ake regular forw ard paym ents against accounts. In its initial stages the system has received an enthusiastic reception with some 3000 prenum bered receipt books issued.

C om puting

C om m encing with the release of bi-m onthly billing early in the financial year, significant im provem ent in several areas of the A u th o rity ’s R evenue System was effected. Specifically, enhancem ents to the C ashiering, Billing, Recovery and P ensioner R ebates subsystem s were com pleted, as well as a new subsystem to produce accum ulated history inform ation from the data base.

T he A u th o rity ’s com puter systems are now m ore than 7 years old. It is appropriate, therefore, that a m ajor review of A D P needs should be produced in order to ensure that changing requirem ents are addressed speedily and cost effectively. A ccordingly, the A uthority engaged consultants during the year to investigate the report upon the A D P requirem ents of the organisation.

FIN A N C E

T rad ing Results

T otal operating incom e for the year am ounted to $113.7 million, com pared with $101.6 m illion in 1982-83. T o tal operating expenditure, plus a prior-year adjustm ent relating to the accrual of em ployee benefits, am ounted to $106.5 m illion com pared with $93.5 m illion in the previous year. As a result the surplus transferred to G eneral R eserve was $7.2 million — aro u n d 6 p er cent of total revenue.

E lectricity Sales

In physical term s total energy sales equalled 1618 G W h, representing an increase of around 5 p er cent over the 1541 G W h sold in 1982-83. T he average return on sales was 6.0813 cents p er kW h, increasing by 7.8 p er cent over the return for the previous year.

A pleasing feature of the 1983-84 sales distribution was the increase in the quantity of off-peak energy sold. W hile still only a fraction of energy consum ed, the alm ost 400 p er cent increase over 1982-83, from 0.50 G W h to 2.46 G W h, is encouraging.

T he total cost of energy purchased and delivered grew by around 13 per cent to $69,895 m illion, representing 74 p er cent of total operating expenditure (net of expenditure relating to recoverable work) — a proportion sim ilar to that of 1982-83.

E xpenditure

T otal o perating expenditure in 1983-84 was $106,531 m illion, which included, for the first tim e, the figure relating to costs of recoverable work carried out — $11,542 million. T he com parative figure for 1982-83 was $94 283 (recoverable

work expenditure — $10,521 m illion). O p e ratin g and distribution costs held constant at $4,673 m illion com pared to $4,633 m illion in 1982-83. It is expected however that over the next few years these costs will increase as the A uthority finds it necessary to apply increasing

resources to m aintenance of substations, subtransm ission and distribution systems. T he com bined influences of grow th of the overall system and aging of com ponents dictate an escalation of m aintenance program s and a greater frequency of random failures due to storm s, interference by trees and other

factors.

16

A dm inistration and general expenses showed an increase from $8,691 million to $10,443 m illion. N et expenditure on the m aintenance and operation of Electricity H ouse increased substantially to include $88 000 on inspection and repairs carried out on the facade, $187 000 on airconditioning plant and $106 000 on upgrading and refurbishing lifts. Provision of im proved site am enities accounted for $107 000, while external insurance cover cost $117 000.

As predicted in last y e a r’s report, interest charges decreased from $4,952 million in 1982-83 to $4,790 m illion as loan com m itm ents were reduced.

Distribution of Revenue $113 753 988

Computing, billing and collection expenses 1.92%

Superannuation L iab ility

T he A uthority has received advice from the D epartm ent of Finance that the rate set in the past for em ployer contribution to the C om m onw ealth

S uperannuation Schem e has been insufficient to meet the growing liability of the scheme. A precise assessment of the A uthority’s accrued liability is currently u n d er review by the A ustralian G overnm ent A ctuary. H ad this figure been available, provision would have been made out of funds transferred to the General R eserve.

N O T E S T O A N D FO R M IN G PART OF T H E FIN A N C IA L S T A T E M E N T S

1. A ccounting P olicies

T he following accounting policies have been observed in prep arin g the A u th o rity ’s financial statem ents:

(a) Accounting Basis T he A uthority is required to keep proper accounts and records in accordance with the accounting principles applied in commercial practice. T h e financial statem ents are prepared in accordance with section 33 of the A .C .T . Electricity Supply Act 1962 and are presented in a form approved by the M inister for Finance. T hey have been prepared on the basis of historical cost and do not p u rp o rt to disclose current values.

All am ounts have been rounded to the nearest thousand dollars and, where an am ount as a result of the rounding is reduced to zero, that am ount is shown to the nearest dollar, by way of note.

(b) Non-current Assets and Depreciation T he depreciation accounting system provides for the value of each type of asset to be depreciated by equal annual charges over the estim ated service life of the class of assets. See Note 13 for details of the non-current assets and am ounts of depreciation charged.

D epreciation is charged on identifiable assets from the date of

acquisition. W ith non-identifiable assets, e.g. D istribution M ains, a full y e a r’s depreciation is charged in the year of installation and none in the year of disposal. Profits and losses on the retirem ent of non-current assets are w ritten off to the R evenue A ccount after taking into account am ounts set aside for depreciation.

(c) Stores and Materials Stores and m aterials on hand have been valued at average cost.

(d) Employee Benefits T he A uthority m aintains a provision in its accounts to m eet its liability to staff for long service leave and recreation leave. T he Liability is split into current and non-current com ponents by estim ating entitlem ents which will be taken within one year. T he A ustralian G overnm ent A ctuary reviews the adequacy of the provision for long service leave at regular intervals and determ ines the am ount to be charged annually to the provision. In accordance with accepted accounting practice the Authority has created a Provision for R ecreation Leave during the 1983-84 financial year.

21

C reatio n of this provision reduced the net profit of the A uthority by $1,836,237.

(e) Insurance T h e A uthority acts as a self-insurer except for: • catastrophic losses; and • fire and extraneous perils — Electricity H ouse and the Kingston Store

— for w hich external insurance coverage has been obtained. T he insurance provision is appraised annually and changes are charged against revenue. Losses are charged against the provision.

7. B ushfire P ro v isio n Following a bushfire which took place w ithin the A .C .T . in F ebruary 1979, the A uthority was served with a nu m b er of Suprem e C ourt writs. As a result of legal counsel the A uthority is proceeding to settle claim s arising from th at fire, out of C o u rt, on a ‘w ithout prejudice’ basis. T he A uthority has

considered it prudent to set aside an am ount towards paym ent of these claims. As at 30 J u n e 1984, an am ount of $2 500 000 was invested externally to support the P rovision (see Note 15).

21. R esources P rovid ed Free of Charge T he A uthority leases a n u m b er of blocks of land w ithin the A .C .T . from the C om m onw ealth, on which are located the Zone Substations assets of the A uthority. T h e A uthority pays a ‘pep p erco rn ’ rental for the use of the land, which can only be used for the purpose defined in the lease. U nder

those circum stances the land has no com m ercial value to the A uthority.

22. C ontracted E xpend itu re C om m itm ents

As at 30 Ju n e 1984 the A uthority had unexpired lease com m itm ents for its W oden and Belconnen branch offices, and an office in B raddon, to the value of $216 669. Expenditure of $84 090 is expected for lease commitments in the ensuing 12 m onths.

2 3 . U nread C onsum ption

O n 1 J u n e 1983 the A uthority com m enced changing its billing cycle for dom estic consum ers from quarterly to two m onthly. T he transition to a full tw o-m onthly cycle was not com pleted until the end of J u n e 1984. As at 30 J u n e 1983 there were still a significant n u m b er of quarterly accounts rem aining unread, consequently the unread consumption continued to increase. H ow ever, as the two m onthly billing cycle was in complete operation by 30 J u n e 1984, the am ount of unread consum ption shows a decrease on the previous year.

D ear Sir

A ustralian Capital T erritory Electricity Authority R eport on Financial Statements

P u rsu a n t to sub-section 33(3) of the A ustralian C apital T errito ry Electricity Supply Act 1962, the A ustralian C apital T errito ry Electricity A uthority has subm itted for m y re p o rt financial statem ents for the year ended 30 J u n e 1984,

com prising: R evenue S tatem ent, Balance Sheet, S tatem ent of Source and A pplication o f Funds, and N otes to an d form ing p art of the financial statem ents. A copy of the statem ents, which are in the form approved by the M inister for Finance u n d e r sub-section 33(1) of the Act, is attached.

I now report that the accom panying statem ents, which have been prepared in accordance with the historical cost convention and accounting policies outlined in N ote 1, are in agreem ent w ith the accounts and records of the A uthority and in my opinion:

• the statem ents are based on proper accounts and records; • the statem ents show fairly the financial operations for the year ended 30 Ju n e 1984 and the state of the affairs of the A uthority at that date; • the receipt, expenditure, and investm ent of m oneys, and the acquisition and

disposal of assets, by the A uthority during the year have been in accordance w ith the Act except th at, contary to provisions of sub-section 28(2) of the Act, the A uthority had invested in the official short term m oney m arket

during the year and had $1.5 million invested on deposit with an unapproved bank at 30 J u n e 1984; and, • provision in the n atu re of reserves m ade in the accounts is adequate.

Y ours faithfully
