Australia has the largest untapped natural deposits of uranium in the world.
Uranium seems less important at this point, unless I'm missing something. Sure it's needed for nukes, but that's mostly a matter of getting a greenlight from the UN as far as I understand it. As well as being able to carry out enrichment. And you only need like 10 to make total war with you not worth it. Maybe you guys can start the largest nuclear energy economy.
