Australia stands to be the nation that can do so damned much towards pushing for a green future right now.
It's a mining powerhouse with access to the minerals needed for future green energy tech. It should be able to mine them more safely, wholesomely, and justly than pretty much any other nation. Mining stuff like lithium is an ugly business, but doing it in a country that has basic labor and environmental protection rules with the technology to do so at scale would be huge. If the Aussies really dedicated themselves to it, current issues with lithium or cobalt could be deflated substantially.
A rational "mining magnate" has everything to gain from a green future, and Australia has an opportunity to become very wealthy in the process -- provided it builds the industry, gets support from the government, and the rest of the world is buying. The IRA in the US means at least that market is very keen on friendsourced raw materials.
