It is !! (Still.)
Even visitors can just come here and fly recreational to CASA rules, and various State rules for National Parks etc.
A few states allow Nat Pk flight, like Queensland, Western Australia, and the NT (NT with a simple free permit).
We have drone registration coming for rec pilots Australia wide, but it has been mooted for several years to be coming in by X date, always pushed off.
Right now it's down for mid year 2023, not sure they will get this off the ground this time either, as it's only a few months away.
We will likely just have drone registration for 250g or more in size, thus I can see Mini size drones will become a lot more popular here in the near future.
