Senator BROWN (4:43 PM) —Mr Temporary Chairman, you will be aware that this bill applies a rebate scheme to diesel and alternative fuels, and by `alternative fuels' is meant `compressed natural gas or liquefied petroleum gas or recycled waste oil or ethanol or canola oil or such other fuels as is specified in regulations'. I ask the minister: how much will this scheme cost in total on a per annum basis, and how much of that cost will apply to each of the fuels that the act lists in its definition?
