Australia is one of my absolute favourite countries. IÕve only lived in Melbourne (pronounced Mel-bun) and Sydney so I can only comment on those two cities. In 2004 I decided to spend 12 months working in Australia. I spent a few months living in Melbourne when I first arrived, before moving on to Sydney where I worked in the hotel industry.
For me, I just love the Aussie way of life and their relaxing attitude to both work and social life. For many people, living in the major cities, the beach is never far away. That, coupled with the outdoor lifestyle, means one thing. YouÕll get a golden tan in no time.

Both Melbourne and Sydney offer a lot of cultural diversity. Each has its own unique charm and you will find many different ethnic communities dotted all around the city and suburbs. The cuisine is varied and can be wonderful and often cheaper for the comparable here in the UK. I have yet to find dim sum - yum cha as they call it down under à anywhere in the UK of the quality I found in Melbourne.
Melbourne has a temperate climate which is more unpredictable than Sydney, and the winter there can be slightly cooler although it does get quite a few scorching days in Summer. I was back in Sydney on New YearÕs Day of last year and the thermometer hit 45¡C! Obviously, the further north you go the more tropical the climate becomes (another factor in deciding where to live).
I've also visited Tasmania, which I found incredibly beautiful but very sparsely populated and a bit isolated from the rest of the mainland. There are no international flights from Tasmania. If you want good international links then Sydney offers the most choice, followed by Melbourne, then Brisbane and Perth.
I suggest visiting both Melbourne and Sydney on your holiday as these are the two largest cities with a temperate climate. But donÕt just stay in the city. Venture out to places further afield, to get a real taste of what Australia has to offer.
