It must be usefull for Dawes,, and It's really cheaper than living in SydenyExpensive. But depends on your life style.

Internet, phone, TV $200 a month
Gas and Water - Unknown (I recon about $100 a month combined)
Going out :-
$10 a beer in a Bar
$60 for a slab of Jim & Coke (24 cans) in a bottle shop
$100 for a nice meal per person,
$50 for an average meal per person
$10 for a cheap takeaway
Petrol is about $1.35 (but add 5c on a weekend, and take 8c off if you use supermarket vouchers)
Cars are expensive. They don't depreciate quick.
Public transport is very cheap, under $10 a day.
These are rare cases IMHO. As far as I know ordinary Sydney citizen earns more than ordinary Perth citizen. Not to mention that head offices of many large companies are usually in Sydney or Melbourne and CEO-s, managers and executives in these places earn a lot more than miners in WA.Human live in perth earn more money than in Sydney
