Yowie Bay Marina sits on Ewey Creek, a freshwater tributary that has fed the Yowie Bay area since Bass and Flinders made their first landing here during their exploration of Port Hacking.

The marina offers floating berths accommodating vessels up to 60 feet, with individual pedestals providing power and water, rubber fender protection, and secure key-card access.

A slipway and antifouling services are also available on site, along with off-street parking.

The marina includes a boat ramp that provides convenient access to the broader Port Hacking Estuary, making it a practical launching point for paddlers and boaters heading toward South West Arm, Bonnievale, Simpson's Bay, or the open waters around Jibbon Beach.
