About 100pw for groceries for 2 adults, 2 kids and a cat
400-600 a quarter as well for electricity
water usage 20 a quarter, but we own not rent so we pay supply charge on top of that
insurance about 40pm for house and again for comprehensive car insurance (this is optional and varies something severe)
internet you can easy get for 50pm
phone is about 80pm for us but we have mobile/landline on there and are still paying out a 24 month telstra internet contract
petrol/car rego/car maintainence varies too much between households to comment

Plenty of other bills sneak up on you as you get older and start to collect Stuff that needs money spent on it. We have 3 sets of insurance (soon to be 4), 2 sets of council rates (soon to be 3), water charges (soon to be 2) and soon 3 houses worth of maintainence bills to pay. And I'm only getting $320 per fortnight in newstart right now and only have 6 months to come up with another $14k for a house deposit! Oh, to be young and house-free again ...
