Can The Cockroaches Survive a Nuclear Option?

A fascinating article about how the federal government took over the states autonomy by fair means and foul.

Even more interesting was the potential civil war between NSW and the federal government in 1930's (Lang vs Lyons) which went as far as the commonwealth government organising the military to take over state buildings (with the NSW police arming up to oppose it).
The governor of NSW instead sacked Lang, resolving the conflict.

Still, I wonder whether NSW, in combination with the other states, could start secessionist movements to force the federal government to be fairer?
