QF94, your probably right about Australia not being militarily invaded but the point is, HAD the Japanese been successful and had they wanted to invade and control the whole of Australia during WW II, Australia and our way of life would be nothing as we know it to be. In these hypothetical scenarios, we'd be the ones looking for sanctuary and I'll wager London to a brick, that not too many of the current xenophobes will be stopping in Indonesia because it's the first country. Nor will they be joining to queue, non existent as it is, to go somewhere to their liking.
Folk should look at photos of POWs of Changi, etc, and then think to themselves, "what would I do if I was treated like that"?
