Prime Minister Kevin Rudd continues his quest on promoting the proposed resources super profits tax and heads to central Queensland to gain support.

Mr. Rudd is expected to commit to a $2 billion fund in infrastructure to the state to match the pledge he made in Western Australia this week.

However yesterday, Mr. Rudd failed to resolve any dispute with the miners over the tax reform during his two-day trip to Western Australia.

Mr. Rudd told a local radio program today that a compromise on the tax may be reached.

"I've seen some of the newspapers this morning that say we're on the verge of a deal. The other newspapers are saying there'll never be a deal. The reality probably lies somewhere in between," he said.

"I think we've probably got weeks and probably months of consultation yet with the major mining companies. We'll work our way through the detail."

Federal treasury spokesperson Joe Hockney criticized the Government's plan to fund billions of dollars for infrastructure projects.

"Today we have the Prime Minister yet again spending money that does not exist," he said.

"He claims to be allocating money to Queensland following a $2 billion allocation to Western Australia. The money will not exist for at least two years."

Retailer Gerry Harvey also questions the Government's tactics on the tax.

"You would expect them to put a bit more thought into it because it's just blown up in their face," he said.

Billionaire miner Andrew Forrest warns that 30,000 jobs will be affected if tax gets implemented.
