Quad bikes are used for very limited operational or scientific tasks in the field. They are only used if other types of transport available are unsuitable for the task.

The bikes used at the Australian Antarctic stations are Honda TRX 420s. These lightweight 4WD bikes are single cylinder, 4-stroke, engine-powered all-terrain vehicles (ATVs). The transmission system includes a 5-speed gearbox and automatic clutch. A key aspect is their low-pressure 'flotation style' tyres which helps with traction and handling, and provides buoyancy in the event of an accidental entry into water.

In addition to these vehicles, the AAD has a range of special purpose vehicles used for specific programs. These include the Bombardier tracked quads which are used mainly by Aircraft Ground Support Officers (AGSOs) on the Casey and Davis ski landing areas and for deep field air operating areas.
