Koomba Park is one of the parks comprising the Dandenong Valley Parklands in the eastern suburbs of Melbourne, Australia. It consists of 92 hectares (230 acres) of which 33 hectares (82 acres) are publicly accessible, and is bounded by Dandenong Creek, Boronia Road, EastLink, Mountain Highway and Burwood Highway in a clockwise direction. It is managed primarily by VicRoads and Parks Victoria. The park opened in December 1981, and its land was previously used for cattle grazing and apple orchards. The surrounding area is still used for grazing. There are three major power transmission lines running through the park: Rowville-Templestowe Single Circuit Southern (1st and 2nd), and Rowville-Ringwood.
