Here are a couple of the links that I've found to be helpful. They aren't super fancy, but I still use them frequently even though I already live here.

For public transport....enter your info into the journey planner
TransLink - public transport information

To get more information about Brisbane and it's suburbs you can check out the living in section. I used it to help me compare the two areas I was most interested in etc.
Brisbane Queensland Australia - suburbs - maps - accommodation - events - street and business directory - restaurants - ourbrisbane.com
They living section will give brief overviews of each area. I still use the website to find activities to do with my toddler, new restaurants to try etc.
