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?

Book a Guided Birdwatching Tour

There are two licensed birdwatching tour operators for the Western Treatment Plant – Melbourne Birding Tours (Peregrine Tours) and Firetail Birdwatching Tours including options tailored to your interest and experience.

Self-guided Access (Birdwatching Access Permit)

To birdwatch at the plant outside of a guided tour you’ll need to apply for birdwatching access permit. You will also need to have access to a car to reach these vast sites.
