Mount Martha South Beach is a stunning north-west facing stretch of coastline located on the Mornington Peninsula in Victoria, Australia. The beach spans approximately two kilometers and is naturally divided into northern and southern sections by the mouth of Balcombe Creek. Characterized by its steep beach slope and usually deep water close to the shore, Mount Martha South offers a dynamic coastal environment including broad, shallow outer bars and deeper channels, creating an engaging setting for beachgoers and water enthusiasts alike.
The beach is backed by a vegetated bluff with quaint small boat sheds nestled between the bluff and the wide 50-meter sandy shore. The area is popular for its picturesque bathing boxes, a distinctive feature of the Mornington Peninsula, adding historic charm and photographic appeal. Mount Martha South has a relaxed village vibe contrasting with busier nearby beach areas, with the beach accessible from the adjacent Mount Martha Village which offers laid-back shopping and alfresco dining options.
The beach is well-loved by locals and visitors for its natural beauty, tranquil atmosphere, and opportunities for a range of water-based activities, while the presence of the nearby Mount Martha Life Saving Club ensures a safe environment for swimmers and families. Seasonal erosion occurs but is actively managed through government restoration projects, preserving the unique character and accessibility of this popular coastal gem.
