The Federal Government remained pressured by Queensland miners to bend the rules on the resource super profit tax, however, the Treasurer is still not swayed and insisted the request may not happen too soon.

Treasurer Wayne Swan told media yesterday he is still determined to get the implementation, and adds that almost 80 miners are currently in consultation with the government. Several anonymous miners, he said, already expressed privately that they can pay higher tax.

Mr. Swan also may rule out the changes of the 40 per cent rate and the profit threshold of 6 per cent as a long-term bond rate before the tax begins.

The mining sector revealed their frustrations, particularly those who already have existing projects.

On Monday, the mining sector won support from Queensland Mines Minister Stephen Robertson, who believes the profit threshold before the implementation of the new tax should be higher from 6 per cent to 11 per cent.

Mr. Robertson raised his concerns that the new tax on Queensland's liquefied natural gas industry will be highly affected since four major companies are due to make final investment decisions on their projects.

Eric Ripper, Labor Opposition Leader for West Australia, agreed with Mr. Robertson that tax should kick in at a higher rate than 6 per cent.

BHP Billtion's new chairman Jac Nasser warned that if government continues to push through with the 40 per cent tax on miners, it would create a negative impact on Australia.

"The risk is that Australia could now be seen by the rest of the world as a less stable and less competitive place for long-term investments," Mr Nasser said in a statement to investors.

Investment plans from China were also scrapped after learning of the proposed mining tax.

WA Chamber of Commerce and Industry president Peter Hood believed the government is willing to wait to finalize the details of the new tax as its implementation will not start for another two years.

He also urged mining companies to hold talks with the government and present their financial modelling to show the potential impact of the tax.
