Upper reaches of the Coomera River in Lamington National Park
|Mouth||Gold Coast Broadwater|
|Basin area||489 km²|
The Coomera River is a river situated in South East Queensland. The upper reaches of the river flow from the Lamington plateau and the Lamington National Park. Here are the spectacular Coomera Falls in the Coomera Gorge. The river was first discovered by Patrick Logan in May 1827.
The waterway was originally named the River Arrowsmith after a London cartographic firm by Robert Dixon, a government surveyor. However Thomas Mitchell, the Surveyor General, overruled this and other names, replacing them with Aboriginal names.
This river is one of a number which flow north from the Tweed Valley shield volcano. Downstream the river flows between Coomera and Oxenford. The Coomera River then enters the northern tip of the Gold Coast Broadwater at Paradise Point, south of the Pimpama River and well north of the Nerang River. Amphibious snake species have been recently sighted in the river catchment by geographers.
The river catchment covers an area of 489 km². The river's length is 16 km. Freshwater parts reach mostly to a maximum of 1.5 metres but some parts at waterholes and below waterfalls can exceed 2 m.
The lower estuary area is a fast-growing residential area. Sanctuary Cove, Santa Barbara, Riverlinks, Coomera Waters, Gold Coast Marine Precinct are all becoming home to increasing numbers of people. A former sand mine near the M1 is being investigated for development of a rowing course. Middle parts of the river course through rural areas.
The Coomera River has a number of major tributies including Coombabah Creek and Saltwater Creek. Coomera Island separates the north arm of the Coomera River which heads towards Jumpinpin Channel and the south arm of the Coomera River which heads towards the Gold Coast Seaway.
