There's a 'learn to drift' course in Eastern Creek but their website hasn't been updated since last year. It's much cheaper than the BMW driving course, and looks a hell of a lot more fun but it's not defensive driving. You do however learn how quickly things can get nasty driving a car too fast around corners.
Here's the info anyways: http://www.sdt.com.au/DRIFT.htm
Thanks for those links. I only got my learners on Friday, but I am interested in doing some of those defensive driving courses, but the ones up here in Brisbane. Holden does a defensive driving course, but its a lot more expensive than other defensive driving schools, plus im more interested in any other cars apart from Ford and Holden.
