Wyndham Harbour Marina is a purpose-built, world-class marina situated on the northwestern shores of Port Phillip Bay, near the mouth of the Werribee River at Werribee South — approximately 30 minutes from Melbourne's CBD.

Completed in 2015, it provides boaters with direct access to Port Phillip Bay and serves as a gateway for fishing, sailing, and coastal cruising, including routes toward the Point Cook Marine Sanctuary.

The marina accommodates yachts, powerboats, and personal watercraft across a range of wet berths, and offers marine services including a fuel dock, private boat ramp, waste pump-out station, and maintenance facilities.

Beyond its boating infrastructure, Wyndham Harbour functions as a broader waterfront precinct with dining and recreational amenities, making it a well-equipped base for both resident berth holders and visiting mariners.
