Given how concessionary taxes and retirement funds (superannuation) make FIRE in Australia an almost completely different approach than most other countries (maxxing out super, first home buyers scheme, and the after tax ASX invesments); what would be the best countries to live as a nomad in?

Since my aim is to retire between 45-50, my after tax investments is only there to support me to around 60 which is when my superannuation is accessible and should support me for the rest of my life comfortably. Considering the value of the AUD, and the fact that a large portion of my money wont be accessible even if I do retire early, what are some places that my money would go farthest in while still having a high standard of living?

I was looking at places like Singapore and Japan but the visas seem impossible to get for long term expatriation.

Any advice? Place suggestions?
