What's on City of Melbourne

Trin Warren Tam-boore

Trin Warren Tam-boore (Bellbird waterhole) was previously five hectares of little-used land in the north-western area of Royal Park adjacent to a busy freeway. Launched officially in 2006, this area has been transformed into an urban wetland designed to treat stormwater run-off from the roads, rooftops and gutters of surrounding suburbs, provide a habitat area for wildlife and deliver recycled water for use in Royal Park.

Wetland structure

The wetland consists of two linked ponds. The ‘treatment wetland’ acts as a natural filter, with banks densely covered by native Australian plants that treat and clean stormwater through natural biological processes. The processed clean water then goes to the ‘storage wetland’, which is used to irrigate areas of Royal Park in summer, while the remainder flows through to Port Phillip Bay.


Collect a self-guided walk brochure from the Town Hall or the Visitor Centre at Federation Square and learn more about the features of this urban wetland at your own pace. You can also download a copy below. Look out for the information signs at each point which describe the history, functions and the plants and wildlife of the wetland. It takes one hour and 30 minutes return if you follow the suggested trail, but you are welcome to vary your walk as you please.
