Niue.
Queenslanders are boorish; South Australians are boring. Matter of personal preference, really.
Do you mean Nauru?
Niue is a dependency of New Zealand in Polynesia (New Zealand took over those British colonies that didn't want independence, except for some reason Pitcairn.) Over half of Niue islanders actually live in New Zealand rather than on Niue these days. IIRC NZ's ethnic structure is something like 82% White, 10% Maori, 6% other Polynesian. (And the appropriate racial slur for a new arrival from Polynesia is "fob".)
It's also ultra-socially conservative. From what I understand the island is completely dry, no alcohol allowed at all, and fishing is illegal on Sundays.
Anyway, probably ACT if what hugh says is true, what are the laws like? To find out more, I'll probably have to research on where the best strip clubs are.
