Fortescue Metals Group (FMG) owner Andrew Forrest called on the federal government Thursday night to simply make good on its earlier economic promises instead of attacking certain personalities.

Forrest singled out Federal Treasurer Wayne Swan, who weeks ago had criticised mining billionaires for using their wealth in undermining the economic programs of the national government.

It was understood that Forrest, along with fellow resource moguls Clive Palmer and Gina Rinehart, were the target of Swan's critical essay, which was recently published by The Monthly.

Speaking at the Western Australia Chamber of Commerce and Industry on Thursday, Forrest qualified his opposition to the minerals resource rent tax (MMRT) as largely motivated by its inherent flaws and not to counter government initiatives, as claimed by the Treasurer.

The FMG boss noted that by its design, the MRRT will only benefit giant miners, which he added had earlier approved of the tax plan in secret meetings with Prime Minister Julia Gillard.

As approved by the Senate on Monday, the MRRT will impose 30 percent tax on the super profits of iron ore and coal miners though presumably the same companies will also enjoy tax breaks of up to 29 percent within the same scheme.

Even as the government looks forward to rake in revenues of some $11 billion out of the newly-approve tax program, Forrest claimed that large mining firms, such BHP Billiton, Rio Tinto and Xstrata, will end up enjoying more than enough reduced corporate tax.

The MRRT was configured to deliver lower company tax on businesses, big and small, a provision that the Australian Green Party has worked to revise.

Forrest lamented that the government appears to have overlooked that component of the mining tax, especially on the part of Swan, who he accused of using too much energy in faulting individuals who were successful enough to enjoy wealth.

The miner told his audience that there was nothing with people like him, stressing at the same time that he has been using his holdings to create more wealth for Australia and for more Australians to enjoy - a fact that he hoped Swan would start appreciating.

The problem was, Forrest said, Swan dismissed people like him as unpatriotic just because they boldly point out what they deem were errors in government initiatives.

"If you happen to disagree with the treasurer then you're un-Australian, undemocratic, probably communist," Forrest was reported by BusinessDay as saying on Thursday.

Forrest has affirmed too that his issues against the MRRT will be formally brought before the Australian High Court, which reportedly will be backed by West Australian Premier Colin Barnett.

Barnett, however, declared that the WA government will not launch a similar legal challenge against the mining tax despite indications that the new laws will lead to conflicts regarding the collection of mining royalties by state and territory governments.

Also, Forrest said that instead of creating unnecessary tensions with business people, Australia will be better served if only the national government will follow through with its earlier pledges of uplifting the state of Australians, especially that of the Aboriginals.

In this case, it is high time for Ms Gillard to implement the Australian Employment covenant that will provide basic training skills for the country's indigenous population, Forrest said.

The program was agreed upon by former Prime Minister Kevin Rudd, the mining boss noted.

"Business people have stepped up, the Indigenous people have stepped up and now I ask the Australian Government step up with job specific employer-directed training," Forrest reminded the government.
