Factbox: Policy implications of Australia's Labor-Greens deal

CANBERRA (Reuters) - Australian Prime Minister Julia Gillard signed an agreement with the Greens on Wednesday to support her push to form a Labor minority government.

The Greens hold one seat in the lower house, but will control the balance of power in the upper house Senate from July 2011, when Greens support will be crucial to pass any laws.

Here are some of the policy implications:

* The agreement ensures the Greens will support budget supply bills, and support the government in any no-confidence motions.

* The agreement commits the treasurer and finance minister to brief the Greens regularly on economic matters and budget preparations. But Treasurer Wayne Swan said the Greens would not be involved in developing the budget or fiscal policy.

* The government's proposed 30 percent profits-based tax on

big iron ore and coal mines -- which would kick in at around 12 percent -- is not mentioned in the Labor-Greens agreement. Gillard on Wednesday ruled out making any changes to her mining tax plans in order to appease the Greens in the Senate.

The Greens support an original plan for a rate of 40 percent, and they want the tax to raise at least A$2 billion more, but their leader has ruled out voting against it if their position is not respected.

* Climate policy is the biggest area to change under the Labor-Greens agreement. Gillard has agreed to set up a new climate committee of lawmakers and experts, who will work toward a policy to price carbon pollution. That will now take precedence over Gillard's election policy of holding an assembly of 150 people, to build a community consensus for carbon trading. The agreement makes no mention of government plans for carbon trading, or the Greens' wish for an interim carbon tax.

* Gillard and the Greens have agreed to hold a referendum in the next three years to give constitutional recognition of indigenous Australians.

* The other main issues in the agreement are for parliamentary reform, and for changes to disclosure laws for political donations that will ban foreign donations and anonymous donations over A$50.
