The South West of WA (Cape to Cape) is magic, I lived in Margs for 4 years in the mid 90's. But its a bit sharky now...also unless you have some particular skillset, your going to be lucky to get some crap low paying job that allows you to scrape by paying for your high cost of living (SW accommodation & necessities like food are very expensive).
Albany...great place, I've spent a lot of time there. But it does get very cold in winter...
As for the rest of WA, you can have great paying jobs in the mining sector & then fly to Indo on your week off. I'd probably recommend that if you don't mind working long hours for a couple of weeks. Just leave your board in Bali & don't acquire material possessions other than a few clothes & a laptop. You could easily put money away for your future.
I do love Northern NSW & could easily live there if all my family were there. But I spent a couple of years on the Great Ocean Rd Vic in the late 90's, almost bought 40 acres over looking the beach at Wild Dog Creek. But I missed my family, came home, met a girl & got married (& heard Apollo Bay had a real estate boom 2000-2001 dammit but missus is pretty cool

).
Otherwise I think working towards acquiring skills that are in demand anywhere in the country. Once you've done that, then you can truly live anywhere you like & do trips overseas, rather than worrying how your gonna scrape up the cash to pay the next bill. Jobs like a trade, chef or nursing.
