Maybe have a look at: (as at 2006) best I can find at present.

ADRs supposed to be Australia wide but the Politicians can't help themselves, so other States may be different. But just a chance every State is the same.
So the regs relating to Driving lamps are:
• Two additional pairs of driving lamps may be fitted to a motor
vehicle.
• The driving lamps must be mounted symmetrically on the vehicle.
• The light emitted must not cause the driver discomfort either
directly or indirectly through the rear view mirror and/or other
reflecting surfaces of the motor vehicle.
• Driving lamps must not be placed wider than the dipped beam
headlamps.
• The colour of light emitted from driving lamps must be white.
• Additional driving lamps must only operate in conjunction with the
high beam circuit and must be fitted with an independent on/off
switch.
• There is no individual height specification for the fitting of driving
lamps.
and A driver must not use, or allow to be used, any light fitted to or in the driver’s vehicle to dazzle, or in a way that is likely to dazzle, another road
user.
