Hi Darky.
The closest is Goulburn (110k north), Cooma (110k south), Moruya (170k east), Adaminaby (170k south) or Tumut (200k west by road - only 60 by air).
There's no RA flying in Canberra.
There should be no issues in taking a few lessons with someone else. It can be vey useful to get a different teaching approach and change of scenery.
You might be able to get a Cheetah experience while you're here if you like. It's highly recommended.:cool_shades:
Cheers,
Ross
