2WG may have their own AOC and aircraft but they are by no means the only place in Australia in the AAFC where a cadet can learn to fly. Elementary Flying Training Camps (EFTC) are also held in 1WG (North QLD), 3WG (NSW), 4WG (VIC), 6WG (SA), 7WG (WA) and 8WG(NT). Tasmania doesn't miss out and they either arrange for civvie instruction or have their cadets travel across to 4WG.
All WGs tend to run their EFTCs under the auspices of another flying organisation. Sydney Flight Training for 3WG as an example.
