Brisbane is a fairly young, modern city. It's well planned and the river runs all the way through it, making for some very unique sightseeing and spectacular accommodation options. I never liked Brisbane but it's become quite cultural with loads of events throughout the year. If you're not really bothered by lack of beaches, then Brisbane is a city worth considering. It's one of those cities where you can get pretty much anywhere in a car within half an hour. And everything is at your fingertips. It's easy to see why people are migrating there from the southern states. 

The weather is consistently warm all-year-round with temperatures rarely dipping below 15C unless it's winter but even then it's usually just the overnight temperatures that drop a bit but it heats up rather quick and can get up to about 21 in winter and upwards of 30 during summer. High humidity can be an issue for some.
