I can confirm this. Brindabella Flight Training closed in April this year. They continued operating in a limited capacity to finish off a couple of full-time CPL students commitments, and are due to complete this phase of the shut down this month.
You can still hire a couple of aircraft from them that are privately owned, but other than that... The aero club have a handful of planes.
There were 6 schools here 10 years ago. There were at least 3 or 4 when I first started to learn here. I think there is another thread call 'Going Going Gone...." (or similar) that has more details.
Nads.
