Brisbane

Too much to write, need to narrow your options.

Old Petrie town is worth a Sunday visit for quiet day with the family. Markets and steam and fire museums.

Try to avoid the highway traffic at peak hours is beyond rediculous, 2 lanes north mostly and it backs up for hours.

Noosaville and Mooloolaba have some nice beaches but will be a bit too cold for a few more months, underwater world is ok for kids but I was disappointed.

Drive around the places you want to move to at peak hour. There is a boom in people moving here so prices have recently gone crazy. The further away from the city, the worse the traffic, so unless you can work from home or public transport. Rentals are basically not available.
