Australian Greens Leader Senator Bob Brown held a press conference to discuss superannuation tax fairness, and the Three Capes walking trail in Tasmania.

What a year to be Green!

Right from the start, 2011 has been a year of victory for the planet and for a more compassionate, equal Australia. Together we have achieved great things!

Australian Greens Leader Bob Brown today urged the big banks to pass through the full Reserve Bank rate cut to customers.

"Australia's banking sector, the strongest in the world, has been generously supported by the government and does not need more assistance - granted by the banks to the banks at the expense of customers, or tax cuts at the expense of public services," Senator Brown said in Launceston.

Australian Greens Leader Bob Brown spoke to reporters in Hobart today about politicians' salaries, immigration, equal marriage, the Gillard government's failure to implement conservation clauses in the Tasmanian forests agreement, and the revelation that the Liberal election policies were not properly audited.

Australian Greens Leader Bob Brown responds to the Gillard Government's budget update and outlines the Greens' more responsible approach. Speaking to reporters in Canberra, Senator Brown also answered questions about the Gold Pass, the Murray Darling Basin plan and immigration.

"The Gillard Government's plan to balance the books by imposing a higher ‘efficiency dividend', a tired euphemism for public sector cuts, is short-sighted and driven by political constraints," Australian Greens Leader Bob Brown said today.

The Australian Greens today released official Treasury costings obtained under formal arrangements as part of the agreement to form government. The costings show that abolishing a range of fossil fuel subsidies would help to re-balance the budget.

"Billions of dollars could be made available for the public over the next four years if the Gillard government adopted measures proposed by the Greens to raise revenue fairly and reduce distortions in the tax system," Australian Greens Leader Bob Brown said in Canberra.

The Australian Greens' efforts to secure a fairer mining tax have so far resulted in another $140 million for the public purse, to offset the $100 million that MP Andrew Wilkie arranged with the Gillard government to hand back to mining companies, Greens Leader Bob Brown said today.

Australian Greens Leader Bob Brown and the Member for Melbourne Adam Bandt talk to reporters in Canberra about the mining tax, after the Prime Minister's MRRT announcement.

Senator Brown said superannuation taxation arrangements can be made much more socially equitable and the Gillard Government's open cheque book approach to refunding mining companies for royalties paid to states should be reviewed by the Senate.

Adam Bandt also commented on his move in the House of Representatives to amend the McCarthyite Building & Construction Commission bill.
