From what I've seen, rent is VERY expensive inner city Melbourne. Easily over $500 pw. Where I live in the US, you can live for a month for that much money.
I would like to live a commutable distance from Melbourne, far enough that rent is cheap enough to own a car, but close enough to urban environments that I don't have to worry about encountering any snakes ( I am terrified of them).
I am also a bit of a gear head, so I absolutely love and am enthused with cars. And Australia has some very nice and affordable used vehicles! :)
