Hi JetBlast, I think we've chatted here before we got our 489 visas. Hope the move's worked out well for you?
I'm in same situation. We've settled well in Adelaide and I hate the thought of throwing away money on rent for another 4 years, so debating about taking the hit with the extra costs. Also looking into idea of buying house with my sister who is a citizen, but not sure if that's going to be too complicated with regards to tax implications for her.
