Hey Dave,it's next weekend 20-21 March(Saturday is the better day normally)Don't quote me but i think it's $10.00 per day or $15.00 for both with additional burn outs Sat Arvo/night.To get there head for Toowoomba,take the Gatton turn off,follow the road into town,turn left at the lights onto old Toowoomba rd. i think it's called,theres a KFC or Red Rooster on the corner,stay on this road for about 2 k's or so and it will be on your left,there will also be signs and cars parked in the park to your left,really quite easy.
The track is still in the built up area of an industrial estate.

Cheers
