Hi Im living in Warner which isn't too far from the places your looking at I have visited some of them and this is only my opinion. Hope it helps.
Deception bay...some nice areas and some not so nice areas....biggest problem is that is has a stigma attached to it that it can't seem to shift,no matter how much it has developed. I actually meet the Mayor and he is very proud of his local community,he ran a fun day and I meet loads of other familys and there is plenty in the community to keep you busy.
Mango Hill /North Lakes are in the same area.... Mostly new houses and loads of other pommies which can be good if your feeling a bit lonely cause it can be easier to make friends,houses are beautiful and you really get the wow effect when driving round...however sometimes it reminds me of living in a bubble...everyone you meet is english and all the houses are the same...this maybe fantastic for some but for others who came to embrace the aussie lifestyle it might be dissappointing.
Brighton/Margate are part of Redcliffe and I can not recommend it high enough,its really beautiful with lots to do ,near the water and feels like a proper holiday town.loads of different houses and loads of old houses.... I personally did not want to live in an older wooden house that needed renovated and as a result we struggled to find a house in our price range.Again redcliffe has a stigma attached to it that it can't seem to shake off but when you get a chance to visit I bet you will think its lovely even if you choose not to live there.
Scarbourgh is again like redcliffe only expensive...to get a nice house there you need to get your wallet out!!!
Rothwell/kippa ring I dont know much about Ive only been to the shops ..sorry.

Thats me off now.
