Interesting discussion.
I remember when crossing the border from NSW to VIC it was 'almost' like going to another 'country' [nation]: It was very different. It had trams and conductors, VFL and more that could not be found in another State.
It was its own 'self' in style and personality.
But then Australia seemed to 'fold back' upon itself or 'fail'.
People like Pauline Hanson took the country backwards into the past, rather than the future.
Australia was already 'One Nation' - but its States were developing their own characteristics, culture, personality, style, etc.
Alas, since 2000 - it all got 'generalised', it went 'backwards' like as if it was the USA (where independent States 'united' to become 'One Nation').
I honestly think this 'failure' currently will also 'fail' completely.
Those in Politics who fold back into the past will lose any empowerment... and we will find that the 'future' of Political Australia will indeed be for something better than just States becoming INDEPENDENT COUNTRIES.
I see provincials like Eden-Monaro, Capricornia, Wimmera, Riverina, St Vincent, New England, Orara, Pitjantjatjara, Centralia, Gippsland, Kimberly, Pilbara, Sterling, Cape York (*BigOl64

) and more... becoming their own INDEPENDENT COUNTRIES.
This would turn this currently BORING continent into a vibrant 'self-sufficient' MULTI-CULTURAL region without the need for FORIEGN multi-culturalism.
Bye bye boring Australia and boring Pauline hansonites who are justified by the Media.
Hello a new versatile Australian continent of much 'self-sufficient' variety
