Obviously there are Provincials (regionals) who have more of something than others and less of something than others.
The Riverina has a lot of food production over other areas - that would be its main income, for example.
Trade between all the Provincials would create a jobs boom like nothing the Federal level of Politics has been able to provide.
Of course, the International community would hate to see Australia 'self sufficient' and have a booming self-sufficient population growth to go with it.
How nice would it be to live in a Provincial area where the majority of your Provincial earnings go back into your area and not siphoned out to the Federal level and sent overseas to fund Indonesia and other 'draining' nations.
Hang the Parliament, next Election.
Vote for more Independents (reflection of Provincials becoming independent).
Dis-empower the position of PM which serves the interests of the USA anyway.
Dis-empower the position of G-G which serves the interests of the UK anyway.
Both positions of PM & G-G are 'self-destructing' anyway...
...who knows, maybe the whole 'show' at Federal level is self-destructing anyway and it won't be a matter of choice for Provincials to go independent - more a matter of survival.
