William Bay Infrastructure Renewal Project – William Bay National Park Trail Closures


Park infrastructure work is being carried out in William Bay National Park.

Bibbulmun Track

Walkers should be aware of heavy vehicles when crossing William Bay Road.

There will be no access to Greens Pool along William Bay Road from 3 February 2020 and throughout the construction works. The park will be fully closed to visitors during this time period, however the Bibbulmun Track and campsite will remain open to walkers.

Walkers MUST remain on the Bibbulmun Track during this time and not use Madfish Bay Road, the Munda Biddi Trail or enter the construction site.

Munda Biddi Trail

The Munda Biddi Trail is closed for 13.2km due to William Bay Park Infrastructure Renewal. A 10.6km diversion is in place along The Heritage Rail Trail. This is a dual use trail. Riders should be aware of horses using this trail. The original route will remain closed until declared safe.

For your safety stay on the marked diversion, adhere to and follow all signage and instructions from Parks and Wildlife and other emergency staff. Riders should be aware of heavy machinery and other traffic in the area.


Construction works are expected to be completed by the end of June 2020.
