Suburb profile
Mount Observation sits up in the Alexandrina hills, a smaller community where elevation and tree cover define the mood. Life revolves around the local community, with the wider region offering trips and services when needed. Ridge-top pockets and tree cover give the area a cooler, greener hillside feel.
Families and commuters make up much of the community, with plenty of young families in the mix. There is a settled, neighbourly feel to the area that rewards people who like knowing their patch.
Housing is well-priced for what you get: space, location and everyday convenience.
