Banjup is a semi-rural suburb located within the southern portion of the Perth metropolitan area in Western Australia. Situated approximately 25 kilometers south of Perth’s central business district, Banjup falls under the jurisdiction of the City of Cockburn. The suburb is bordered by suburbs such as Treeby to the north, Forrestdale to the east, and Hammond Park and Aubin Grove to the west. It is accessible via Armadale Road and is close to major transport links such as the Kwinana Freeway, making it relatively convenient for commuting while retaining a quiet, country feel.

Banjup is characterized primarily by its large residential lots and semi-rural lifestyle, with most properties featuring acreage and significant green space. The zoning regulations in Banjup have traditionally restricted higher-density development, resulting in a landscape dominated by single detached homes on plots typically ranging from two to five hectares. As of the 2021 Australian Census, Banjup had a population of approximately 2,849 residents, most of whom are families and individuals seeking a blend of rural tranquility and metropolitan accessibility.

Commercial development within Banjup is minimal, as the local planning intention remains geared toward preserving its rural residential character. The suburb contains limited retail or industrial properties; most residents access commercial services in neighbouring suburbs such as Cockburn Central and Success, where shopping centers, schools, and healthcare facilities are more prevalent. In recent years, northern portions of Banjup have experienced some residential development, with new housing estates in nearby Haynes and Atwell, but the core of Banjup maintains its distinctive low-density, green, and peaceful environment.
