The Oxley Creek (Yagara: Benarrawa) is a creek that is a tributary of the Brisbane River, located in suburban Brisbane in the South East region of Queensland, Australia. Rising in the low hills in Scenic Rim Region, water from the 260-square-kilometre (100 sq mi) large catchment area flows into Oxley Creek as it flows through the western parts of Logan City and into Brisbane. At 70 kilometres (43 mi), the Oxley Creek is Brisbane's longest creek and the only sand-based one in the city.
