I think barnaby gave some good advice here. Give yourself an 18-month timeout from your movement to buy in Oz, or at least 12 months if you’re impatient.
I realize it’s hard to resist a lower price than you’re used to, but think also about the absolute price you’d be paying. If you can’t see it being likely that you would be able and happy to pay that much cash for the same home at some time in the next 10 years or so, then the price is probably still too high. Otherwise you’re relying on the “greater fool” theory or you’re planning to never retire or do many other things with your future earnings.
