Sydney or Queensland Forever Home

We arefeeling disillusioned on where to live we currently live in Windsor NSW but have previously lived in South western Sydney, inner west, northern sydney, western Sydney and northern beaches.

We are looking for suggestions on what areas to look at we dont want to go up north past Hornsby but at the same time we dont want to be that south we are past Kiama. We are also looking at the option of relocating to QLD it has been suggested that Hope Island could be a good fit of what we are looking for but not knowing the area we are open to all suggestions.
We are looking for that real community feel where you can see trees and feel as though you are in the country but at the same time be close to the water/beach ideally we would like to be close to nightlife, places to eat, good schools and grocery stores. We want the area to be safe to walk, ride bikes for kids to play and ultimately enjoy the area and what it has to offer.
