Koonung Creek (or Koonung Koonung Creek) is a small tributary of the Yarra River in Melbourne's east. The creek originates in Nunawading near Springvale Road, and flows to join the Yarra at the border between Ivanhoe East, Bulleen and Balwyn North. The place the two waterways meet forms the borders between these suburbs. Bushy Creek (now carried by an underground pipe) is a tributary to the creek, joining near Elgar Park in Mont Albert North. A shared use path follows the course of the creek (and therefore also the Freeway), known as the Koonung Creek Trail.
