What are the good and bad points of living in the Southern Moreton Bay Islands?

I'm considering moving there in the future and am very familiar with facilities, layout etc. To help with my decision to move I would really appreciate info on things such as: why you moved/didn't move there. How did you like it once moved? How long you've lived there/did live there and do you see yourself there for a while yet. And lastly what benefits do you see in living on the islands? (especially Lamb and Karragarra)
