Meet the site
The Mandorah Queen was a 22 m steel-and-aluminium ferry on the harbour crossing to Mandorah. Cyclone Tracy crossed Darwin in the early hours of 25 December 1974 with gusts estimated at over 200 km/h, destroying most of the city and killing 66 people, many of them at sea. More than 20 vessels sank or were driven ashore in and around the harbour, and several of those wrecks now form a second, much more intact wreck trail beside the 1942 sites. During the storm she dragged her anchors and sank with three crew aboard, one of the harbour's saddest losses that night.
The wreck lies in 18-21 m and is almost buried in soft, shifting sand. It appears to be sitting upright, but so little is exposed that it is difficult to tell, and DSAC notes that each visit shows less of her as the sand builds up. It is also hard to locate and to anchor on. The reason to persist is the fish: large jewfish, greasy cod (groper), flathead, batfish, angelfish, butterflyfish, rock cod, coral trout and dense schools of baitfish gather around what structure remains. This is a site for experienced local divers and club outings rather than visitors, and a reminder of the people lost on the water during Tracy. Because the exposed structure changes from year to year, it is worth asking DSAC about recent visits before committing a neap window to it; on a good day it can be combined with the nearby NR Diemen as a shallower second dive on the Mandorah side of the harbour. Divers should treat it as a grave site and leave everything as found.
Research this site before booking Stored site notes may be historical. These questions highlight gaps without turning old instructions into a current dive plan.
Mandorah Queen is recorded as Wreck in Darwin Harbour. The listed access is boat (day trip). Confirm the actual meeting point, route and permission to visit; a map pin does not establish any of these.
Topics flagged by the stored research
These are questions prompted by the existing notes, not a verified or complete hazard assessment.
- Current and timing
- Ask how the operator assesses the current window for the actual route. Historical tide notes are not a departure instruction.
- Water movement
- Ask how swell and local exposure affect the proposed entry, exit and route.
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.
Questions, answered
Is Mandorah Queen suitable for my certification?
The record lists Advanced Open Water. That does not establish suitability for every route or day. Share your training, recent experience and equipment needs with the operator and ask about the specific proposed dive.
Can I book Mandorah Queen through YouDive?
YouDive is an independent research directory. Contact an operator directly to confirm whether it currently runs the trip, the inclusions and the booking terms.
