Farcebook ; Auster Aeroplane Enthusiasts Downunder. Plenty of info and help available there.
Auster J2. "Arrow" . 2 seat trainer, 90 hp Continental. Crz 80 kts. A pensioners aircraft. Easy to push/pull in and out of the hangar. Can fly with the door off and keep yr head warm with the helmet (gives better sound protection and radio hearing too).
A J5 and 0-320...like fun but faster.
