It's a tad more expensive to live in Australia especially for housing (and that's not in a capital city) but some things are similar.
Prices in AU$ 1 : US$0.79
Monthly costs unless stated
Housing - $500pw
Utilities - $150 electricity is now almost $0.30/kw
Car Insurance - $100 depends on car insurance history
Food - $500 approx
Two iphones Mobile Phones - $150 for both.(can do cheaper on prepay with own handset)
Cable/Internet/Phone - $100
Health Insurance for two - $250
Gas for the Vehicle - $AU $1.30/l
Where I live is sub tropical near the ocean so not too hot rarely over 32c Ave max 29c / min 23c and not too cold winter max 21c/ min 10c
Downside for anyone looking for expat lifestyle is getting a residency Visa is very difficult and expensive. We have plenty of people who do live as expats here especially British, South African, Canadian and a few from USA.
