Stony Creek Backwash (Williamstown Workshop, Piers & Stony Creek Backwash)


Stony Creek Backwash (Williamstown Workshop, Piers & Stony Creek Backwash)

The Stony Creek Backwash marks the end of a journey for Stony Creek; here it flows into the Yarra River under the soaring arches of the Westgate Bridge. The intertidal mud flats of Stony Creek Backwash are fringed by mangroves and saltmarsh which are a haven for waterbirds.

The timber boardwalk section of the Stony Creek backwash is now closed to pedestrian access, as the structure has reached the end of its design life. However, viewing platforms remain at each end of the old structure, where you can see the mangrove and saltmarsh habitat which extends around the backwash.

From here, you can also see the decommissioned portion of the old Stony Creek timber boardwalk, which previously extended across the breakwater. This area has become an excellent place for local birdlife to roost, making the viewing platforms a great place to visit for birdwatching activities.

You may also spot the footings of temporary piers used in the construction of the West Gate Bridge, and the bund in the Yarra River protecting pier 12, and the wreck of an unknown vessel and the remains of the former railway line that once travelled from Spotswood.

The fluctuating tide at Stony Creek Backwash makes it a popular area for fishing.

Cycling is a great way to explore the Stony Creek Backwash. The Hobsons Bay Coastal Trail passes by Stony Creek; the trail forms part of the Bay Trail and runs from Cheetham Wetlands near the mouth of Skeleton Creek to Stony Creek.

Adjoining the Backwash, Westgate Memorial Park is a memorial to the 35 men who lost their lives on October 15, 1970 in the West Gate Bridge Collapse.
