The Western Treatment Plant (WTP) is one of the most popular sites for birdwatching in Victoria, with 284 species of bird recorded at the site. You must apply for a permit to bird watch at WTP, and must register each visit. A special permit may be needed to access some areas of the plant.
The site is vast and a car is required to access the permit areas.
Total fire ban days
You are not permitted to enter the Western Treatment Plant on total fire ban days. Before you visit, please check the Country Fire Authority (CFA) website to see if a ban is in place.
Birdwatching permit types
There are two types of permits for bird watchers at WTP:
general access permits
special access permits (requires a one hour safety induction)
Each permit type specifies the areas within the plant you can access. You will be given a key along with your permit to unlock gates within these specified areas.
To determine which permit you need learn about bird species at the plant and where to find them.
You must be 18 years or older to be eligible for a permit. Your permit is valid for two years from the date we approve it.
