What are the average Utility Bills for a 3 bedroom house in Australia?

Depends on which state you live in. Generally most houses have gas as well as electricity, perhaps $250 a quarter each for gas and electricity. Water bills could be anything from $70 a quarter if some is covered by rental owner, to more than $200, depending on how much water is used. Rent tends to be cheaper in outer areas with access to train and buses, anything from $250 and up, generally expect to pay around $300 to $400 in rent a week and more in the city. Units are cheaper, in some areas from $200 up. 3 bedroom units are hard to find but can be found, from $250 up.
