Senator WILLIAMS (New South Wales—Nationals Whip in the Senate) (15:04): I have a further supplementary question, Mr President. I refer the minister to the 38c a litre fuel excise collected by the federal government. Given that the coalition had frozen this excise at 38c a litre in 1999, will the minister guarantee that the government will not increase the excise in the May budget on fuel or reintroduce indexation on the fuel excise?
