Artificial underwater feature
Elsa’s Reef
Elsa’s Reef is the first of the outer artificial features recognised on Extreme Watersport’s regular Rye dives. We have repeatedly observed shopping trolleys, bicycles, pipes, a small bear ornament, table-like objects and bottles among the manufactured structures. These observations describe a changing assemblage, not a permanent inventory.
Independent photographic evidence adds another view of this habitat. In the Australian Museum’s 2021 exhibition guide, Rachel Price documented Pale Octopuses among discarded bicycles, metal grates and shopping trolleys at the named Elsa’s Reef location in Port Phillip Bay.
That photograph was taken at approximately 6 m. This is the depth of a photographic observation, not a depth profile for the whole feature. Australian Museum source.
