Overview
Inner West Council, in funding partnership with the NSW Government, has restored part of the historic Gumbramorra wetland at Mackey Park, Marrickville.
It officially opened in July 2026 as part of Council's NAIDOC Week program.
The Gumbramorra re-creation returns part of Marrickville’s lost wetland landscape and create a thriving ecological space that will offer the community a renewed natural landscape, historical connection and a culturally significant future-proof place. The project will expand the existing raingarden into a fully functioning multi-pond wetland system with open water, marsh areas, seasonal flood zones and terrestrial plantings.
The new wetland:
- Mitigates flooding on the Mackey Park sports fields
- Provides habitat for birds, frogs, turtles and other wildlife
- Honours the cultural and environmental significance of Gumbramorra for local Aboriginal Peoples
- Offers the community a unique space to explore, learn and connect with nature
A raised walkway, the Reconciliation Walk, takes visitors through the wetland, with viewing points and interpretive features to share the story of Gumbramorra and its importance to the Gadigal and Wangal.
Before colonisation, Marrickville and Sydenham were part of the vast Gumbramorra system – a seasonal wetland that grew and shrank with tides and rainfall. It was a biodiversity hotspot, home to countless species and a vital source of food, medicine and cultural practice for local Aboriginal peoples.
Following colonisation, European settlers drained and industrialised the swamp, dismissing its ecological and cultural importance. Drainage infrastructure was built to pump water out of Gumbramorra, and the land was eventually industrialised. Despite these attempts to dry out a historic wetland, frequent flooding has remained a challenge for the local community. The loss of Gumbramorra came at immense environmental and cultural cost, and proved to be a gross mismanagement of land, causing many ongoing problems.
Re-creating a small part of Gumbramorra will help restore balance by providing a natural method of drainage, bringing back wildlife, and reconnecting the community with a unique part of the Inner West’s natural history.
