Here in Australia 'wog' refers to persons of Mediterranean descent (Greek, Italian, Lebanese, etc). Stereotypically, they love dance music, R&B, leather jackets and souped up cars and live with their parents. They're favourite saying is "Siiiiick mate." This stereotype has been exploited wisely by Nick Gianopolous in numerous plays (Wogs Out of Work, Wogorama, Wogboys) and most recently in a number one box office hit in Australia called The Wogboy.
