The Event is intended for Production Cars, categorised as Classic and Modern Sports Cars, Sedans and Utility Vehicles, being four wheeled vehicles, capable of legally carrying 2 person's minimum. The acceptance of entries of Low Volume cars as defined by the CAMS Tarmac Technical Regulations Article 3.5 shall be at the discretion of the organisers. Competitors intending to enter such cars shall make application to the organisers prior to lodging an entry.

All competing vehicles shall comply with Schedules A & R of the CAMS Manual of Motor Sport and the 2012 CAMS Tarmac Rally Technical Regulations or comply with the Technical Regulations for events run as part of the CAMS Australian Targa Championship. Non complying cars may be able to enter Killarnée Targa South West subject to CAMS approval.

NOTE: These changes to the Tech Regs now bring us much closer to having a single set of regulations covering all tarmac rally cars across Australia. Inevitably there will be some minor differences such as open top cars still not eligible to compete in KTSW or QTW events, but the purpose is to make the majority of tarmac rally cars eligible to compete in these events.
