Phil visits Sydney to help Alastair Hewson and David Luxton buy a city-centre pad. Sydney is Australia's most iconic and famous city, which, with its popular mix of relaxed beach lifestyle and busy cosmopolitan culture, is also one of the most expensive places to buy property in the world. Work colleagues Alastair Hewson and David Luxton are clubbing together to buy a place. Since being sponsored by their company to relocate six months ago, Alastair and David have been forking out nearly £2000 a month on rent, so they are in a rush to buy.
