Hi, I just read this thread.
Wow, I cannot believe that you are considering to move over here. Excellent
Brisbane is a quite place all year round and it can get pretty hot in summer time, I would only go there for a holiday because I like the fast paced life. You could buy less expesive property in Brisbane closer to the water than you could in Sydney.
Australians are very friendly and relaxed people. Someone compared the Australian way and level of life with Canadians' to some degree and you have nothing to worry about here. The culture shock is not that huge. We speak english and we have a lot of people from all over the world. The food is great, you will find lots of fresh vegetables, sea food etc.
The beaches are amazing and the water is so warm and beautiful full of hungry sharks.
I would recommend our country to anyone!
