According this source [1], only about 35% of all bauxite is mined in Australia, so I don't think that's true.
What's crazy is how modern shipping has made it economical to process this elsewhere, all over the globe. For example, from one of the biggest bauxite mines, in Pará, Brazil, the raw bauxite is shipped across the Atlantic to be processed by Hydro in Norway, which refines it into alumina powder, which is then shipped elsewhere to be refined into aluminum. You would think it would be more cost-effective and energy-efficient to centralize this, not to mention more environmentally friendly.
