Australia has no nuclear power stations and the current Gillard Labor government is opposed to nuclear power for Australia, as are the Greens, the party with the current balance of power in the upper house. However, Australia does have a small research reactor (OPAL) in Sydney, and it does export uranium. Australia has 40% of the world's known uranium deposits as well as similar deposits of the other potential fission reactor fuel thorium, and sells uranium to members of the Nuclear Non-Proliferation Treaty.
