The Federal Government is urging mining companies to cooperate with the new reforms on super profits tax.

Federal Resource Minister Martin Ferguson on Tuesday admits to media that many of the industry do not like the idea of tax. He said consultations may run for a year, allowing more time for changes.

"I've never found a company that bends over backwards and says, 'Please put in place a higher tax for me,' " Minister Ferguson said.

He adds that the new legislation will be discussed in the next parliament meeting.

"We therefore want the companies to model it, to come into the Treasury process to open their books on a confidential basis, and to actually take us through the design issues that may cause them concerns in the transition, especially for existing projects."

The government explained that tax must be imposed to protect its growing profits from Australia's minerals from going offshore.

However, Mitch Hooke of Minerals Council argues that there is a lot of money staying in Australia due to the global financial crisis.

Nick Minchin, former resource minister and incumbent liberal senator slammed the government's tax plan in a local program.

"They think you can just go and tax all these industries and not care about it and they'll always be there," he said.

Meanwhile, the Australian Council of Trade Unions welcomed the changes and reforms made by the government through a massive new tax on miners. The unions said that retirement packages should not be seized by big multinationals.

The Australian Industry Group said the government only touched on a few issues such as the mining tax, tax cuts on small businesses, and the superannuation, adding that it still has a long way to go since the review talks about long-term reforms.
