The Zealandia was a Huddart Parker passenger liner that carried Australian troops in both world wars, and she was at anchor in Darwin Harbour when Japanese aircraft attacked on 19 February 1942. Bombed and set on fire, she sank on her side at the entrance to East Arm. A Japanese salvage company cut much of her up for scrap in 1959 and 1960, so what lies in about 22 metres today is a long line of wreckage rather than a ship.
John Brown and Company built the Zealandia at Clydebank, Scotland, for Huddart Parker of Melbourne, completing her in May 1910. She was a twin-screw steel steamer of 6,660 tons and 125 metres. For her first three years she was chartered to the Union Steam Ship Company of New Zealand, mostly on the trans-Tasman run but with voyages as far as Fremantle and Vancouver, and Huddart Parker then used her between Melbourne and Fremantle.
In 1918 she became an Allied troopship, carrying American troops to France, and after the armistice she brought Australian soldiers home. Between the wars she worked the Australian coastal passenger trade. In the Second World War she carried units of the 8th Division to Darwin, Rabaul, Singapore and Timor, and on 20 December 1941 she sailed from Darwin with 207 women and 357 children, the first of the ships that evacuated civilians from the town. A month earlier HMAS Sydney had escorted her to the Sunda Strait, and her crew were the last Allied people known to have seen the cruiser before it was lost with all hands.
The Zealandia reached Darwin from Sydney on 6 February with an anti-tank company and its guns and ammunition, and some of her cargo was still aboard when the raiders came. She could not raise enough steam to work her anchor winch, so she stayed at anchor. One bomb went into No. 3 hold beside the engine room, rupturing the bulkhead and setting the cargo and engine room alight. A second hit the starboard quarter and set the aft accommodation on fire, fire also broke out in the forward hold where ammunition was stowed, and low-flying aircraft strafed her with machine guns.
The crew abandoned ship. She turned as she sank and came to rest on her side, leaving only her masts above the water. Two crewmen, able seaman James Masson and fireman Patrick O'Connell, later died of their wounds aboard the hospital ship Manunda. The raid was the largest attack by a foreign power on modern Australia, and it sank at least seven large ships in the harbour.
The Navy removed her anchors, chain and other small fittings soon after she sank. In 1959 and 1960 the Fujita Salvage Company of Japan cut away much of her hull structure and her engines for scrap. Its divers broke the harbour's wrecks apart with dynamite and underwater gas torches, and a floating crane lifted the pieces out. Fujita had 77 bronze crosses made from Zealandia scrap for the new Darwin Memorial Uniting Church on Smith Street, which opened in July 1960.
The Australasian Underwater Cultural Heritage Database (AUCHD) puts the wreck in 22 metres of water at the entrance to East Arm; Wikipedia gives 19 metres. Remote sensing shows the classic cigar shape of a shipwreck, but AUCHD says site inspections found little semblance of hull integrity. What remains is a significant length of ship structure, examples of the ship's systems and some cargo, including asbestos sheeting. Leave all of it, the asbestos especially, exactly as it is.
Nobody has published an account of the marine life on the Zealandia. Dive Darwin lists turtles, sharks, dolphins and manta rays among the animals seen on its harbour wreck tours in general.
Yes, but plan it properly. The Zealandia is protected under the NT Heritage Act and the Commonwealth Underwater Cultural Heritage Act 2018. Under the Commonwealth Act you must not disturb, damage or remove anything, and any new find must be reported within 21 days. AUCHD records a 100-metre radius zone around the wreck, but it is not among the protected zones declared under the Commonwealth Act, and it is not one of the two Darwin Harbour sites under a harbourmaster's closed-waters order (those are the Booya and Catalina 6). The NT Government's advice is to contact the Heritage Branch to find out whether you may dive a wreck and whether you need a permit. Dive Darwin's guided tours include the permits.
The wreck also lies in a working port. AUCHD's GPS position for it falls on the southern edge of the East Arm shipping channel as Darwin Port defines it in Port Notice PN011, and the same notice bars masters from anchoring in a shipping channel except in an emergency. Wikipedia describes the Zealandia as a recreational dive site, and 50 Great Dives lists it among the other great dives around Darwin.
Port Darwin's tides have a maximum range of 7.8 metres, a mean spring range of 5.5 metres and a mean neap range of 1.9 metres, and the currents they drive are complex and strong. The NT Heritage Branch's brochure for the USS Peary, another 1942 wreck, talks in terms of diving on a well-planned neap tide.
Visibility is the other limit. No figures are published for this wreck. For the Mauna Loa, elsewhere in the harbour, the NT Heritage Branch says the seabed is silty and easily stirred up by divers and tides, and that visibility rarely exceeds two to three metres even on a well-planned day. 50 Great Dives gives 5 to 15 metres and a water temperature of 27 to 30°C for the same wreck and rates the dry season best. The dry season runs from about April to September.
Box jellyfish are most likely in NT waters from 1 October to 1 June, but stings have been recorded in every month, and their venom can kill in under five minutes. NT first aid for a sting is vinegar, never fresh water. Saltwater crocodiles are abundant in the Territory again, and the Parks and Wildlife Commission runs a crocodile survey and trapping program in Darwin Harbour itself.
The Zealandia is a boat dive. Dive Darwin runs five-hour guided harbour wreck tours from Dock 2, Stokes Hill Wharf (Sea Darwin Cruises), from 7am to 12 noon. Each tour visits two of the harbour's roughly 90 wreck sites, which also include Cyclone Tracy wrecks and sunken illegal Indonesian fishing vessels. Scuba gear, a guide, permits and lunch are included, groups are capped at nine, and in October 2026 the tour was listed from AUD $440. Dive Darwin requires PADI Advanced Diver certification and a minimum age of 15. The booking page does not name the two wrecks, so ask whether the Zealandia is on the plan.
For any dive outside an operator's permitted tour, contact the NT Heritage Branch first (08 8999 5039, heritage.branch@nt.gov.au).
The Larrakia people, who call themselves the Saltwater People, are the Aboriginal people of Darwin and its harbour. The USAT Meigs and SS Mauna Loa guides cover two more of the 1942 wrecks, the British Motorist lies about 1.3 kilometres to the west, and the Darwin Harbour Wrecks site page covers the harbour as a whole.

Visibility at SS Zealandia typically ranges from 2 to 15 metres, though it shifts with swell, wind and recent rainfall. June-September (dry season, outside the 1 October to 1 June stinger season) generally offers the best conditions for diving here.
