I think that VH-MAW had the Scouts logo, as did the C172s. I don't think UQS had the logo at that time. The photos I've seen of Scout aircraft in recent times show that they've still got a Scout logo on them- albeit a 21st century version rather than the 'in your face' purple one of 20 years ago.
The Scouts and AIRTC didn't 'share' facilities per se. The AIRTC operation had it's Nissan hut towards the top of the hill and they used that for lectures, admin, etc. They may have staged some Ops out of the Scouts but I wouldn't have classified that as 'shared' operations. I always viewed it as a Scout facility/ AOC/ aircraft that the AIRTC were lucky enough to utilise for their flying activities.
As far as I know, the Scouts still run a very robust program on weekends and still enjoy excellent facilities.
