Meet the site
The Song Saigon is the largest of Darwin's Vietnamese refugee boats and the centrepiece of the harbour's artificial-reef complex. Unlike the wooden fishing boats in which most refugees arrived, she was a steel vessel of about 40 m (130 ft) and 200 gross tons, described variously as a small tanker or coastal trader. DSAC records that she was hijacked and sailed to Australia by refugees; she brought 34 people to Darwin in 1979. Between 1976 and 1981 more than 50 boats carrying Vietnamese refugees reached Australia's northern coast, most of them arriving in Darwin Harbour. Several of the steel boats were later cleaned and scuttled west of Cullen Bay together with a redundant construction barge to create a fishing and diving reef, and the site was extended in later years with a confiscated illegal fishing boat. The group sits in 20-25 m within a few hundred metres, and some operators have linked the wrecks with rope so that more than one can be visited on a dive. The Song Saigon was scuttled in 1982 by the Dinah Beach Cruising Yacht Association, the Darwin Amateur Fishing Association and the NT Fisheries Division.
She sits upright and relatively intact on the bottom in 21-25 m. Several of her holds and the deckhouse are open and can be looked into with a torch, and after four decades the hull carries good coral and sponge growth. Fish life is very good: golden snapper, cod, jewfish, batfish and trevally swarm the structure, and stonefish sit camouflaged on the deck and superstructure. Being the most ship-like of the complex, it is usually the first wreck divers visit here, and with the John Holland Barge and the Ham Luong so close it is one of the few places in Darwin where you can see several wrecks in a single neap-tide window. Local divers suggest taking several slow dives rather than trying to rush all three.
Research this site before booking Stored site notes may be historical. These questions highlight gaps without turning old instructions into a current dive plan.
Song Saigon 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.
- Lines and obstructions
- Discuss any known entanglement concerns and the suitability of the planned area.
- 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 Song Saigon 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 Song Saigon 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.
