Mr FORREST (11:08 AM) —Mr Deputy Speaker Georganas, on indulgence: the minister has made reference to my background—hence my interest. I was impressed with the attempts of the member for Corio, the member for Werriwa and the Minister for Resources and Energy to explain the technical nature of the amendment. To put it in simple terms, the challenge of surveying is to take into account the curvature of the earth. It is not a two-dimensional profile; it is three-dimensional. Add to that the fact that petroleum exploration is conducted two and three kilometres below the surface of the earth. The title is actually a concentric keystone in three dimensions with a curved surface; that is probably the best way I can explain the challenge to laymen. But I commend those members who have attempted to explain the highly technical nature of the bill.

Question agreed to.

Bill read a second time.

Ordered that the bill be reported to the House without amendment.
