As an Australian, I find it odd that Perth didn't rate as high as either Sydney or Melbourne which came in as 10th and 17th respectively. Perth ranked 21st overall but wasn't shown on the list associated with this link. Sure, Perth does not have the nightlife or the population density that either of those 2 cities have (1.1 million vs ~4 and ~3.5 respectively) but then again, Perth has one of the lowest crime rates in the country, the lowest unemployment rate, pollution is nonexistant, fantastic weather (its warm and sunny about 300-320 days a year) and they're currently undergoing a resources boom that is the envy of the rest of the country. The guidelines for defining quality of life can be found on the Mercer Consulting site which conducted the survey.

Full Disclosure: I'm a resident of Perth, but I've lived in Melbourne, Sydney and Brisbane within Australia.
