I really like that part of Qld - although my favourite places are up in FNQ. Unfortunately I'm asthmatic, and a trigger for me is humidity, so I do suffer when up there. Normally it's controlled and I don't need an inhaler (apart from using one preventatively before going for a run) but up there I need to use one morning and night and I still wheeze. If it wasn't for this, we'd certainly consider moving up there. Instead, we visit tactically at the times of year when the humidity isn't so high.
Property wise, I find Brisbane itself overpriced, but not too far out there are some great affordable places. The look and feel of the place is younger than Adelaide, but it's no London (nowhere in Australia is like London for me; whether it's the worst or best of London that's being compared to.) I've not lived up that way, so only see things through a tourist's eyes, but there's plenty to do in the city and lots of places within an hour or so.
