Merlan Inner Reef

Reef Dive | Boat access

Depth: 2 m (6.56 ft) to 7 m (23 ft)

Level: Open Water and beyond.

Merlan Inner Reef is so named after a yacht that struck on Point Lonsdale Reef in the past and drifted ashore just to the North West of this reef. The site lies near Merian Reef in the Port Phillip Heads Marine National Park. This is a boat dive that can be dived on each side of the slack water. When a moderate swell is running keep clear of this site as the waves can break quite easily here, so only attempt when the swell is low.

It is a series of small detached reefs that lie in 7 metres of water and come within 2 to 3 metres of the surface. Each reef is separate from the next and you can swim between the reefs quite easily, but just be aware of your location, because if you are swept away, it could be a long swim. The reefs have many caves, ledges and crevices to explore, so take your time to explore and investigate. Often you will see some big Blue Groper or a large Crayfish, as well as many plate size Green-lip Abalone.

This is a dive for the open-water diver to explore a shallow reef system in relative safety. Just remember to plan the dive around slack-water when the currents are diminished.

See WillyWeather (Port Phillip Heads) as a guide for the tide times and the height of the tide.

The Rip & Tides Warning: Always keep an eye on sea conditions throughout any shore or boat dive within "The Rip" (aka "The Heads"). This is a dangerous stretch of water, where Bass Straight meets Port Phillip, which has claimed many ships and lives. Please read the warnings on the web page diving-the-rip before diving or snorkelling this site.

Port Phillip Heads Marine National Park

This site lies in the Port Phillip Heads Marine National Park. The park is made up of six separate marine areas around the southern end of Port Phillip: Swan Bay, Mud Islands, Point Lonsdale, Point Nepean, Popes Eye, and Portsea Hole.

Thirty-one of the 120 shipwrecks known to have occurred within a 10 nautical mile radius of Port Phillip Heads are thought to be within the Port Phillip Heads Marine National Park in Point Lonsdale and Point Nepean.

Aboriginal tradition indicates that the Bellarine Peninsula side of the Port Phillip Heads Marine National Park is part of Country of the Wathaurung people, and the Mornington Peninsula side, including Mud Islands, is part of Country of the Boon Wurrung people.

DISCLAIMER: No claim is made by The Scuba Doctor as to the accuracy of the dive site coordinates listed here. Should anyone decide to use these GPS marks to locate and dive on a site, they do so entirely at their own risk. Always verify against other sources.

The marks come from numerous sources including commercial operators, independent dive clubs, reference works, and active divers. Some are known to be accurate, while others may not be. Some GPS marks may even have come from maps using the AGD66 datum, and thus may need be converted to the WGS84 datum. To distinguish between the possible accuracy of the dive site marks, we've tried to give each mark a source of GPS, Google Earth, or unknown.
