Unless there is something different in Australia, low beam bulbs have two filaments (three terminal) and high beam bulbs have one filament (two terminals.) Typically when you turn the headlights on, low beams you should get the outside bulbs on, and when you switch to the high beams all 4 bulbs should light.
