The Australian Six automobile features a four-door, factory-built open tourer body with two fold-down seats, a horizontally split windscreen and folding hood. The paintwork is tan with white lining, while the mudguards are brown. The interior features tan stretch vinyl upholstery. The steel-spoked, wood-rim steering wheel has an ignition advance-retard control mounted in the centre and a hand throttle for starting and slow running. In the centre of the dashboard are various instruments including a National oil pressure gauge, an ignition lock, headlight switch, drum-type speedometer and odometer by Stewart (M-7) including trip meter, a Westinghouse ammeter, choke and dash light. The float-type fuel gauge is incorporated in the tank. On the centre of the floor is a straight gear lever flanked by top button press handbrake. The step-on starter button is also on the floor, but the car can be crank started. The clutch is a multi-plate, dry disc type by Borg and Beck. The engine is a six-cylinder Rutenber with American Bosch magneto ignition. There are expanding and contracting hand and foot brakes acting on the inside and outside of the rear brake drums. Suspension is by semi-elliptical springs front and rear and there is a built-in tyre pump by Kellogg under the floor, driven off the gearbox.
