For members information - if you get the chance to go to Sydney in Australia its worth hiring a decent [quick] car and driving 2 and a half hours to Bathurst, where you can drive the famous Mount Panorama Circuit for free.
Its a public road. The Circuit is as you see it on TV. Gravel traps, chicanes, concrete wall, grid markings, pit garages etc. You can drive around either way and if you go on a week day its very quiet. The speed limit is 60kph but I defy anyone to stick to that, especially down Conrod Straight where we managed 200kph in a Hyundai Santa Fe. We didnt see one police car.
There is also a small racing car museum which is well worth a visit.
