Coomera River Catchment

The Coomera River catchment lies within the northern part of the Gold Coast and extends into the eastern region of Scenic Rim Council.

The Coomera River traverses through highly diverse land uses ranging from the relatively undisturbed headwaters in Lamington National Park on the New South Wales / Queensland border, through large rural properties in the upper reaches to high density residential and riverside development, particularly in the lower estuary where it flows into the Broadwater near Coomera Island / Paradise Point.

The upper catchment flows through lands used primarily for cattle grazing and through the Land Warfare Centre at Canungra. The lower freshwater section traverses through rural acreage housing, nursery and quarry practices, and modified residential development.

The estuarine section of the river has been impacted most by modification to the lower floodplain for canal estates, marinas and golf courses.
