Australia is expensive mate....You didn't mention where in Australia would you be moving if your wife takes up the offer......Just to give you an idea of costs in Melbourne (Sydney would be more expensive), a decent 2 bedroom accommodation in the suburbs would set you back by atleast $450 a week.......add $150 pw for utility bills........groceries can take upto $150 pw for two people......then add travel costs incl. fuel & insurance for your car...........You need pretty much 1k pw to stay afloat as a couple unless you are willing to cut corners by living in a cheaper suburb that's far out from the city.......if you like eating out be prepared to spend another $100 for a meal for two in a decent fine dining restaurant.......So if you are saving a fair bit of money after factoring these imminent expenses, it's a good call........
