Meet the site
Murra-El-Elevyn is widely described as a magnificent recreational cave dive – by Nullarbor standards. The CDAA describes a 300 m long main tunnel with two interconnected phreatic networks, one passage half-filled with water and another completely submerged, with a large rock formation marking the division between passages. Visiting writers note massive creamy-grey rock formations, depths around 20 m and a silt area where care is needed.
The cave was explored in 1976 during the early South Australian expeditions to the Nullarbor. Today it is dual-rated by the CDAA: the section from the entrance lake to the main chamber is Cave-rated, while the North-West passage (beyond a 60 m line) and related routes including 'Gary's Back Passage' are Advanced Cave, with interesting sidemount passages.
Because it is shorter and shallower than Cocklebiddy or Weebubbie and has a more manageable entry, Murra-El-Elevyn is often the first Nullarbor cave dived by visiting teams. It is still remote, permit-controlled and serious: divers must apply in writing to DBCA at Esperance at least four weeks in advance.
Teams usually combine Murra-El-Elevyn with Cocklebiddy and Tommy Grahams on a single trip based at Cocklebiddy Roadhouse, since all three are within a short drive. The water is brackish groundwater at about 19°C, so a drysuit or thick wetsuit is needed for long dives, and good trim is essential to avoid stirring silt in the smaller passages. Lines should be checked on each visit because shifting boulders and past expeditions have left old line in places.
Research this site before booking Stored site notes may be historical. These questions highlight gaps without turning old instructions into a current dive plan.
Murra-El-Elevyn Cave is recorded as Cave/Cavern in Nullarbor Caves. The listed access is shore. Confirm the actual meeting point, route and permission to visit; a map pin does not establish any of these.
Historical access notes exist for this record, but have not been independently verified for current use. Request current directions from the operator or site manager rather than following an old entry description.
