Australian Prime Minister Julia Gillard is all prepped for bruising confrontations as the Parliament resumes session this week, with two points dominating the Labor-led government's legislative agenda.

Fresh from efforts to shore up chances of Labor retaining government power in Queensland over the weekend, Ms Gillard is expected to ramp up campaigns that would increase the likelihood of her mining tax and immigration policies winning parliamentary approval.

Media reports pointed to the almost certain scenario that the minerals resource rent tax, already years in the making, will finally gain the official nod this sitting, with only the possible glitch coming from the Australian Green Party.

But Greens leader Bob Brown has expressed his intention of voting for the MRRT bill, which when formally approved will be rolled July 2012 and will impose considerable levies on specific mining projects in Australia.

Mr Brown, however, told The Sydney Morning Herald that his party would still want small businesses to be given some form of discounts on the mining tax, the incorporation of which, he assured, will seal the Greens support for the tax plan.

According to Federal Treasurer Wayne Swan, the MRRT will spawn better infrastructures across Australia and will beef up the superannuation fund, which in turn will benefit millions of workers.

The tax is also projected to collect billions of revenues, near-term and long-term, for both states and the national governments, Mr Swan said in an economic note he released over the weekend.

Of equal importance to Ms Gillard is for her immigration plan to gain legislative backing, following the setbacks that she absorbed last year when the Australian High Court declared her Malaysian Plan for asylum seekers as unconstitutional.

The Coalition has consistently rejected the Malaysian component of Ms Gillard's answer to the influx of boat people attempting to reach Australian soils in search of a better future.

Opposition Leader Tony Abbott has been adamant on his stance that making Malaysia as a transit point for intercepted refugees defy humane treatment of the helpless boat people, many of whom encountered abuse and even death in their perilous journey to get to Australia.

The Liberals have been pressuring the government to grant temporary protection visas to apprehended refuges while they undergo processing, which proved a sticky issue between the government and the Coalition.

Yet a possible compromise could struck with the introduction of a bill Independent MP Rob Oakeshott that allows for any country belonging to the Bali Process as possible location for the offshore processing that the government has proposed for the refugee question.

Mr Oakeshott is hopeful that crossbenchers in the Parliament will support his proposal of sending the refuges to any of the 50 nations, which he added have expressed their commitment to resolve the issue of human smuggling.

Immigration Minister Chris Bowen has expressed support for the Oakeshott bill, telling SMH "the Australian people want this sorted out. They say both sides of politics support offshore processing and surely both sides of politics should be able to vote for it."

"I'll be recommending to the Labor caucus we support Mr Oakeshott's bill," Mr Bowen said.

But this early, the Coalition has declared it will oppose the Oakeshott processing plan, stressing that what's at hand was a mere 'carbon copy' of the government offshore processing proposal that the Parliament already found as unacceptable.
