I want to drink your kool-aid.

I feel like they are highly livable if you do not need to work for a living.

Otherwise:

- Adelaide: It's cheap but there are no jobs.

- Brisbane: It's cheap(ish) but there are no(t many) jobs.

- Perth: It's expensive but there are no jobs.

- Sydney: You can't afford it. A one-hour commute is starting to look appealing.

- Melbourne: Can't complain.

They are lovely cities to visit as a tourist. As a worker, there are much better opportunities out there. Australia tech workers have easy access to working visas in practically every country in the world.

Australia will always be there for retirement.
