Comber South ward encompasses the southern neighbourhoods of Comber town along with surrounding rural townlands. The area includes residential streets, local shops, and community facilities centred around the Ballygowan Road and Mill Street. The landscape transitions to agricultural land, with fields and small holdings characteristic of the Ards Peninsula.
A notable local feature is the alignment of the old Belfast and County Down Railway line, now a greenway, tracing the ward's western edge. The area is bounded by the Enler River to the north and includes the grounds of the former RAF Ballyhalbert, linking it to broader regional history. Development is primarily low-density, mixing suburban housing with active farmland.
