Melaleuca Wetlands is a 14-hectare freshwater wetland located between Blackwood Park Drive and Waterford Golf Course, Ferntree Gully. Following the discovery of significant flora and fauna, including platypus in Monbulk Creek, a portion of the former floodplain was rehabilitated in conjunction with adjoining residential development to improve the available habitat and ecological diversity in the area.

GbLA, in conjunction with the Ecological Engineering and Neil Craigie and Associates, designed a system of wetlands, braided streams, ponds and riffles and a lake to fulfil a number of functional hydraulic, ecological and public amenity outcomes and to encourage burrowing and nesting of platypus.

The wider terrestrial landscape areas contain an extensive pedestrian circuit with boardwalks, allowing movement across the floodplain, and an observation deck providing opportunities for viewing expansive areas of open water. The project is seen to be a great success, leading to an increase in the platypus population, improvement of water quality within Monbulk Creek and satisfying a need for residential housing by providing 100 home-sites directly north of the wetland.
