As to flying VFR at night...
(My training included several hours of IFR training under the hood.)
[Edited to add that I've had actual IFR instruction, including flying through clouds, but not enough to try it solo.]
Everywhere
I've flown under VFR conditions at night in the USA, there are so many lights on the ground that there's no chance I could confuse which side is up,
at least under conditions I'd risk flying.
I can easily imagine that most of Australia is far darker on the ground once you get away from coastal regions, hence far harder to discern a horizon.
