Roughly the size of Phillip Island, the Western Treatment Plant provides a haven for tens of thousands of birds, thanks to ample water and a variety of landforms and plants.
The world-class sewage treatment facilities are only a fraction of the site, with vast lagoons home to nearly 300 bird species – some of which travel all the way from Siberia.
The Western Treatment Plant is recognised as a wetland of international importance under the Ramsar Convention, and as one of Australia’s best birdwatching sites.
Species include the Orange-bellied Parrot, Brolga, Pied Cormorant and rare shorebird species.
Fancy seeing some of these species in person?
