"We've got a spectacular resources boom," Gillard said in an interview with Channel Nine television yesterday. "It makes sense to take some money from the turbo-charged section of the economy and share it more broadly around the nation and that is what the mining tax does."
The expansion of China and other emerging economies has boosted demand for resources such as iron ore and coal in Australia, the largest shipper of the steel-making and energy- producing materials.
Gillard, 50, won support from independent lawmakers for the measure in the lower house last November after agreeing to set up a committee to examine coal-seam gas projects and to increase the threshold at which companies will be subject to the tax to A$75 million from A$50 million. The Greens backed the bill after reaching an agreement with the Government on offsetting any resulting shortfall in revenue.
Gillard has proposed that proceeds from the levy on mining profits will be used to reduce the corporate tax rate to 29 per cent from 30 per cent.
The Government's plan to cut the corporate tax rate for businesses with annual revenue of more than A$2 billion may be blocked in the upper house after the opposition coalition and Greens said they opposed the measure.
The Government also won backing for the laws by promising to provide A$6 billion in spending for roads, rail and ports, and increase the amount paid to people's retirement savings to 12 per cent of their salary by 2020 from the current 9 per cent.
Labor sank to a six-week low in an opinion poll released March 13 after Rudd, who was ousted as Prime Minister in a June 2010 party coup by Gillard, stepped down as Foreign Minister on February 22 to challenge her for the nation's top job. He was defeated in a February 27 party ballot.
The mining tax will raise A$10.6 billion in the three years after being implemented from July 1, government estimates said.
Parliament goes into recess from March 22 and resumes May 8, when the Government will announce its annual budget that it says will return to surplus. Under laws already passed, the Government will put a tax on carbon emissions from July 1 by charging about 500 polluters A$23 a ton for discharges until the set price gives way to a cap-and-trade system in 2015.
