Killarney Heights suburb profile

The streets are mainly residential with detached family homes on sloping blocks, many renovated to take advantage of the views, and pockets of native reserves and walking tracks that lead down to foreshore spots.

It suits people after a peaceful, suburban lifestyle with easy access to bush and water.
