Mate, like what is said above the Jobs are in Sydney and Melbourne really. But the cost of living in Syd is on the rise big time at the mo. Over 1000 ppl settle in Sydney every week so the work is here.
Did a quick search in Syney for jobs specifically related to Architecture and 285 jobs came up straight away so Im sure you could find something.
Hope this helps.
Cheers
