Hello there ,we moved to Vic in2010 ,we rented our uk home out .All good really but realised that without the equity from the sale of our UK home we will never afford an Aussie home without working 24/7 till we were 70 if the exchange rate was 1.5 or so. So returned back to uk hoping to see the dollar weaken to at least 2 to 1 before we could ever consider returning . Bottom line DO NOT COME OFF THE MORTGAGE LADDER in the uk because its going to be harder to get back on it if the Aussie trip does not pan out. Rent your house out and see in 12 months because Aussie cannot sustain the level of house prices it has and the housing bubble will burst sooner or later.
