Australia did contribute troops to most US-led military expeditions of the past century. Is it that unlikely that in the event of complete nuclear devastation of the Northern Hemisphere, they would be happy to tip the scales in favour of their allies among the survivors by dispatching a few tens of thousands of troops to mop up what is left of the Russian side, which would only be up against a few disorganised pockets of resistance with no supply chain to speak of?

Also, there is a chance that in the event of a full-blown nuclear exchange Russian leadership would see the showdown as fundamentally civilisational, and seek to take Australia down simply because it is unambiguously an outpost of Anglo-American culture.
