Senator MURPHY (1:06 PM) —No, for the minister's information, I am not worried about the states; what I am worried about is the revenue—the cost of running this scheme. We know from the historical point of view with regard to the Diesel Fuel Rebate Scheme that there were problems with it, and there are probably still problems with it, I would suggest. This is a new scheme. You are starting from a whole new base. At least the tax office have acknowledged that they need information to have some checks and balances in this process. It is that that I am asking you about. Suppose you have, say, a contractor working in forestry who has heavy plant and equipment that is used directly in the harvesting of trees, and the person also has a transport operation not just involved in the transport of wood. To my way of thinking, they could—I am not suggesting they would—actually make a claim for diesel that is not being used in part of their transport operation. They could be using diesel, as I put to the tax office, because nearly all of them have diesel four-wheel drives, as do many of the workers. A whole new diesel usage could occur, for which claims for the scheme will be lodged and paid.

At this time I cannot see, and I have not been informed of, any process of checking proposed to be in place to actually determine that. That is what I am asking you about: I am asking you to inform the Senate of the negotiations between the states on the registration of vehicles and how you then further check registration of vehicles that are put off the road—that is, a bus or a truck that breaks down and is put around the back—but claims continue to be made for them. I suggest that you do not have any mechanism at this time, and the Senate ought to be informed about what you propose to do.
