Made a selection of cities!

• Sydney:Has a great (although often windy) climate and a vibrant economy. The big disadvantage is the cost of real-estate - it's a lot more expensive than elsewhere in Australia. Even if you go to the far western suburbs like Campbelltown, or the Central Coast (Gosford area) you will find your dollar does not go nearly as far as elsewhere in Australia. And living in these areas will involve a long commute if you are working in the Central Business District.
  
  
  
  
• Melbourne:Melbourne's climate is very different to Sydney's. Winters are colder (about 14C/57F) on a winter's day, about 3C/5F colder than in Sydney. That makes a big difference to the lifestyle you can have, especially as Melbourne skies in winter are a lot greyer than Sydney's.
  Melbourne is probably a more liveable city than Sydney, its road system in particular is better. Melbourne's economy is a lot stronger now than in the early 1990s, and it remains the centre for Australia's manufacturing industry. Real estate in Melbourne is about 30-35% cheaper than in Sydney.
  
  
• Brisbane:Has a wonderful climate (winter about 21C/70F), although summer is relatively wet and humid. Brisbane's economy is fast growing and diversifying, and real-estate is far more competitively priced than Sydney or even Melbourne. A downside of Brisbane is that the city centre is somewhat tattier than the other major state capitals in Australia.
  
  
• Perth:Almost like a mini-California, Perth has great prospects. It has possibly the best climate in Australia (mild in winter, hot and dry in summer), a fast growing economy (with a lot of emphasis on resource based industries) coupled with relatively cheap real-estate and terrific beaches and parks. The biggest disadvantage of Perth is its isolation - Adelaide is your nearest substantial neighbour and that's over 3 hours flying time away.
  
  
• Adelaide:Although a lovely city, Adelaide has lagged the rest of Australia in recent decades. Adelaide's biggest advantage is it's low cost of living - it has the cheapest real-estate of any major Australian city. Finding a job is more difficult though, although not impossible. However, if your profession is something like nursing or teaching, Adelaide might be quite a good choice. Nurses and teachers, for example are in demand throughout Australia and because of the low cost of living, people in these professions will probably have a higher standard of living in Adelaide than they would have in Sydney or Melbourne.
  
  
• Canberra:Canberra offers a fantastic lifestyle for you and your family, with an outstanding school system, excellent health services, shorter commuting times, plenty of fresh air and community living. Much of what is best about Australia can be found in the nation's capital - it's a clean, safe and relaxed place to live.
