Another plug for the Aero Club in Canberra - good fleet and hirers get a free carparking pass. Membership very reasonable. Gatekeepers are a very friendly bunch.
Canberra/Goulburn Aviation has a Warrior 2 available at Goulburn for hire -
Welcome - Canberra Aviation. Not much happening at Goulburn so the Warrior is pretty free every day except Saturdays (when everyone wants to fly it!). Their Warrior in Canberra is often booked with training but they refer people to the Aero Club for hires in Canberra in any case.
