I've been a regular competitor at this event for years and @007adr has started racing here too . It's usually a good weekend of racing and this year they've switched it to a 2 lap format.

What: 2 lap sprint on ~1000m bitumen street circuit with chicanes
When: March 5-6, 2015
Location: Gatton Industrial Area, near Lake Apex
Cost: $185

Several classes to suit your vehicle: NA, Turbo, 2WD, AWD, Registered, Unregistered etc. Real easy to enter if you're road registered (helmet, long pants/shirt, fire extinguisher, masked headlights if glass, blue triangle for battery).

Example of racing from last year.
