A diver has died while traversing one of Australia’s most extensive cave systems.

Emergency services were called to Tank Cave at Tantanoola, near Mount Gambier, to reports of a drowning about 10.30am on Sunday.

Police raced to the scene, where they found a 65-year-old Victorian man had died.

An operation with officers from the Water Operations Unit was launched to retrieve the man’s body.

“There are no reports of any other injuries and there are no safety concerns regarding the incident,” South Australia Police said.

Tank Cave’s “extensive maze-like system” boasts more than seven kilometres of diveable passage, according to the Cave Divers Association of Australia.

“This makes it one of the longest underwater caves in Australia,” the Association said.

The dive spot in the state’s southeast is reportedly called Tank Cave because a water tank used to rest over the top of the entrance, where a short ladder first leads divers to a small surface lake.

The cave system previously claimed the life of world-renowned cave diver Agnes Milowka in 2011.

Milowka, 2019, separated from her group to explore a section of the cave when she ran out of air and drowned.

Some of her close friends were part of the team who worked for about a month to retrieve her body — including Richard Harris, who helped save 12 Thai boys and their soccer coach from a flooded cave in 2018.

It also comes just a day after a 60-year-old woman was saved from a West Australian cave system.

The woman was freed about 5.30am on Saturday, after spending 12 hours trapped in the cave system in an area called Empress Spring, in the remote Goldfields.

Emergency services were only able to get her out of the cave with the use of a winch.

She was rushed to hospital with non-life threatening injuries.
