I am in Australia for around 15 years. I had a number of chances to move other states. Every times, at the end, I chose to stay in Brisbane.
I think I made a right choice so far. Last Monday, I went to Canberra for a business trip. I arrived at 7.50 am, that is so cold. The temperature was only minus 4 degree. When I walked out from the airport, that was freezing.
For weatherwise, Brisbane is much nicer. In winter, there is a quite warm, at morning, that is only 11-15 degree. Sometimes, if the weather is good, we have plenty of sunshine, the temperature can be over 20 degree. That is a good place to live!
I am glad to settle down in Brisbane!
