Well not sure that today was the best day to be living in Sydney - but I like it but then I think only a person born in Sydney can put up with a lot of the traffic hassles. But it certainly has a fair bit going for it and you can still get out of the city and in to the country side in just over an hour ( unfortunately we can't compare to Adelaide in that regard).
I lived in Adelaide for all of 1995 - loved it, thought it was great but work moved me back to Sydney, otherwise I may have stayed.
