Hi Hauptmann,
No advantages as yet to sub 250g here.
There are no recreational requirement for drone or pilot regulation as yet, now supposedly mid 2023, but it keeps getting shifted forward (!), and no insurance requirement.

Jut follow the drone rules most of our countries share similarly with minor exceptions.

The apps we have for airspace zones are good to know and download . . . one or more of those as you see fit.
Probably OpenSky, OK2Fly, and Airmap are the most handy for rec pilots here . . .

National Parks and other such are off limits in most states, Queensland, Western Australia, and the Northern Territory are exceptions, where you can fly freely under CASA rules in the first 2, and with an easy, free permit system for the NT.
Watch out for local council / city bylaws (ordinances), many in cities and larger regional towns don't allow model aircraft flight from land under their authority . . . but usually these are buried in their online bylaws (if you can find them at all !), and there aren't usually 'no drone' signs to be found at most parks I know of around the country.
So with caution you can fly where you see fit, I avoid people, go to obscure parts of open parks to fly when testing things etc, and have never had a problem.
If going to really popular parks in the big eastern seaboard cities, you might find more signage here and there.
Enjoy your trip . . . first time here ?
If you post up your rough plan, there might be some tips to other points Aussies can offer in the various states you might be visiting.
