Richmond has an Archer (in very good condition), a C150 (for sale), an Evektor Sportstar, a Mooney M20R and a Cirrus SR22. All these aircraft are utilised by the aeroclub (which must maintained >50% ADF membership).
If you have anything with retractable gear and a CSU that would fit between the Archer and Mooney in terms of pricing then give them a call (on (02) 4587 3214 or Chief Pilot – Mrs Jenny Avery – Mob: 0402 537 624) as they are looking for an aircaft in that category.
There was a C340 in the 285 Sqn hangar at one stage, and a C182 (SRE) was parked in a temporary shelter up near 176 Sqn a few years ago. I don't know what these were there for but I suspect they were being used by base personnel.
