Ok, this is the scoop from the dude that lives in Perth.
You cant buy anything unless you got $300,000 bucks and that would be for a shitty flat in a crap area. In other words that's entry level into realestate. Further you move out of Perth the cheaper it gets but fok that living in the middle of foking know where with all the welfare punters.
Sky's the limit from there but $400,000 will get you a nice 2 bed unit in a good area close to Perth.
For rental in a good area they start around $350 ish but if you want to slum it they start around $ 250 up for a shit box in a high rise 1 bedroom suicide room surrounded by scum.
Up to you as the slappers say.
