Bearing in mind what's happened to property prices and rents in most of the world (including Australia?) over the last decade or so (ie they've gone to the moon), I can't get my head around the idea of coping financially with such a situation, unless one is on a way-above-average income.
In the early 1990s, I owned a house (the one I currently live in), and rented a flat from my employer in London, but that was a different era - the house was bought for £19,000 and the flat had a hugely subsidized rent (around £130 per month). Just renting even the cheapest flat in London today would cost close to £1000 per month, and buying it would cost a minimum of £300,000.
Maybe things are different in Australia, but from what I've read the property market has gone berserk there as well, or is that only in places like Sydney?
I think one other issue you should bear in mind is the question of the management of the place you'd be renting out. I rented out my house for a while when I lived in London, and my experiences with the companies who supposedly 'managed' the property were dreadful. This industry tends to attract the very worst sort of spivvy people, whose main interest is in making large amounts of money for doing as little as possible.
