Leading edge,
yes there is more diversity than previously, I would say. We have more Australians, Malaysians and Indonesians, plus a few S. Americans too. Lots of S. Africans with Pan African.
Not sure who are the best off in real terms, again it depends on your situation; school fees/mortgage, unmarried/no mortgage etc. The Aussies are on about 120,000 AusDoll tax free which must be pretty comfortable!
