Several West Australian businesses will unite along with the premier and other politicians to pressure the federal government to revise its proposed mining tax law from the budget which was released late on Tuesday.

The government confirmed that a 40 per cent tax on super profits will commence on 2012 and will be used as the basis of assisting the economy back to normal.

However, the WA Chamber of Commerce and Industry argued that the government should reconsider as it will hamper the State's prosperity and growth.

"We do not want to derail this future growth that Western Australia and Australia is going to experience through a very onerous tax and that is something we have serious concerns about," said John Nicolau of WACCI.

Mr. Nicolau added the budget may be relying on the new tax, however, the super-profits tax may backlash and will result in a negative effect.

"It will have material impacts and you are hearing that directly from the resource sector now."

On the other hand, Federal Kalgoorlie Liberal MP Barry Haase remarked that the tax on mining industry will put jobs at risk.

"Let's face it, Western Australia is the state that salvaged the national economy at the end of the global downturn. It leads the nation in job creation and investment. You'd be hard pressed to find somebody working in WA that the resource industry's success didn't impinge upon," he said.

Mr. Haase expressed his worries that capital in Australia will be lost as it will become less attractive to invest.

Premier Colin Barnett, who met with several representatives of mid-level companies, say they are worried about the proposed mining tax.

"Now I'm not suggesting that the mining industry will collapse or decline in Western Australia but I believe that probably a quarter of future projects will now not proceed," the premier said.

Opposition Leader Eric Ripper suggested the government should negotiate with the concerned sectors regarding the tax and also welcomes the government's commitment to fund 70,000 new training places to uplift the economy of Western Australia.
