Just did a search & you can also get them from here :

Heaps of other options there too ... !
Although further reading from here & other threads reveals :
Query : Does this Still apply only to NSW ?... The fitting of spacers or adaptors between wheels and hubs,
additional to those provided by the vehicle manufacturer, is not permitted ...
Also can someone clarify the legality of drilling out either your wheels or the hubs,
as I would have thought it would be in same category of illegal modification ...

Note : Should only consider this spacer option if your not worried about keeping your car legal,
as some have suggested previously if going off-road unregistered, insurance wont cover it.
Cheers, Bantum ...
