Custom plates in Australia are carefully regulated. Drivers can't order whatever they want because invariably that would mean permitting a whole lot of profane and sexualy explicit number plates. So instead, drivers who want custom plates have their requests carefully monitored and sanctioned by state transport departments. You never see anything even vaguely offensive on Australia's roads, which makes this a unique case, as it seems the governing body didn't realise what they were approving.
