OK I have since done some digging on my own and the law shows as follows:
242 Australian Road Rules
215 Using lights when driving at night or in hazardous
weather conditions
(1) A driver must not drive at night, or in hazardous weather
conditions causing reduced visibility unless:
(a) the headlights, tail lights and number plate light fitted to
the driver’s vehicle are operating effectively and are
clearly visible; and
(b) if the vehicle is fitted with clearance lights or side marker
lights — those lights are operating effectively and are
clearly visible.
Offence provision.
Note 1 Driver’s vehicle and night are defined in the dictionary.
Note 2 Drive includes be in control of — see the definition in the
dictionary.
Lights and warning devices Part 13
Lights on vehicles (except bicycles, animals and animal-drawn vehicles) Division 1
Rule 216
(2) However, this rule does not apply to a driver if the driver’s
vehicle is stopped or parked at a place on a length of road, or in
an area, to which a parking control sign applies and the driver
is permitted to stop or park at that place under the Australian
Road Rules.
Note Length of road and parking control sign are defined in the
dictionary.
(3) Also, a driver driving during the day in fog, or other hazardous
weather conditions causing reduced visibility, may drive
without the headlights of the driver’s vehicle operating if the
vehicle is fitted with front fog lights and those lights are
operating effectively and are clearly visible.
(4) In subrule (1), a reference to a kind of light fitted to a vehicle is
a reference to a light of that kind required to be fitted to the
vehicle under another law of this jurisdiction.
