Entrance Deep

Other | Boat access

Depth: 30 m (98 ft) to 103 m (338 ft)

Entrance Deep is the very deepest dive spot known of anywhere in Victoria, being the bottom of the ancient River Yarra just inside the Port Phillip Heads in the main shipping channel.

The actual Entrance Deep spot where 103 metres deep has been reached is just 5-metres square. It takes incredible luck to get a shot line down 103 metres into this small 5-metre by 5-metre square target.

Some divers have located this spot by entering at Trimix Corner and descending down the wall looking for the deepest spot they can find. This approach is not always successful.

At 103 metres deep this is not a dive for the faint-hearted. It's very black, barren and rocky, with incredibly treacherous currents. The ascent must be started while the tide is still coming in, slack water is very short, and the ascent must be back up the shot for as long as possible as the outgoing tide will quickly push you back over Rip Bank with a minimum depth of 20 metres. Pick up will be outside Port Phillip Heads.

Bass Strait Warning: Always keep an eye on sea conditions throughout any shore or boat dive in Bass Strait on Victoria's coastline. Please read the warnings on the web page diving-in-bass-strait before diving or snorkelling this site.

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.

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.
