Australia will fall much like Yugoslavia.
Besides a Civil War between the NLP v Unions/bikers/ALP (The Aust rejection of USA influence 'unionism')
Most of the Australian continent will fracture down into smaller 'Independent' Nations (hence why a growing number of 'Independents' in Parliament for starters) to compensate for a long lost 'British' influence.
Australia will be a Republic of 'smaller nations'.
USA: States come together to 'unify'.
Aust: States fall apart ...independently.
We'll have 'provincials' like Hunter, Eden-Monaro, Capricornia, etc.
Even BIGOL64 can tell you that 'York' (Nth QLD) wants to separate from the rest of QLD and there are other regions around Australia that want to go 'Indie' (like the Riverina).
The future of Australia isn't that hard to predict.
The 'Westminster' way works for the UK, which is just a 'colony' of the USA these days, in 'Europe'.
Germany has made the sacrifice to be 'Pro-European', France will have to do the same very soon. Even Russia is pressured to be more 'Pro-European' (and turn its back on China again?
Ouch - that will hurt
).
One day, Britain will have to choose to be 'European' and turn its back on its 'Frankenstein' USA creation.
...btw. Westerners will fail here in Australia. The Eastern Europeans will embrace the 'future' here, while the Western Europeans stay locked (shackled) in the past.
You still better get a gun though
