After an exciting trip back down from the Great Detached Reef – Silentworld II and its full time crew headed up by Captain Michael Gooding responded to a Mayday call on late Thursday evening and rescued two professional fishermen from their sinking fishing vessel north of Cooktown – the team arrived off Flora Reef, south of Cairns on Friday morning.
Flora Reef is the location of HMCS Mermaid, the former surveying vessel of Phillip Park King, which was wrecked whilst on voyage from Sydney (New South Wales) to Port Raffles (now in the Northern Territory) in 1829. After several searches the wreck site of the Mermaid was located and surveyed by the Silentworld Foundation and the Australian National Maritime Museum in 2009 in the first, of what has turned out to be many, successful underwater archaeological research projects.

Flora Reef is also close to the site of, an as yet unresolved mystery, dating back to 1943.In February 1943 the Royal Australian Air-force Catalina A24-25 from 11 Squadron RAAF – went missing off Cairns whilst returning from an anti-submarine patrol – the last garbled message from the aircraft – which was received at Townsville contained the words ‘Force land’. Because the message was received at Townsville rather than Cairns and because of eyewitness accounts from soldiers at a military installation on one of the islands south of Cairns the aircraft was presumed to have crashed near the Frankland Islands. Despite an extensive search the aircraft was not located and the crew of 11 presumed lost – missing in action.
Another perfect day on Great Detached Reef – seas almost mirror smooth – with only a slight breeze from the north – however a 20-knot change from the south-east is predicted to come in sometime in the late afternoon which will make diving on the outer edge of the reef difficult if not impossible – so it is time to get cracking.
Two dive teams away nice and early from the back of Silentworld II – Dive Team One, consisting of John, Peter and Xanthe headed south across the lagoon to exam some possible shipwreck sites that Bungee in his helicopter had seen the day before and Dive Team Two, made up of Frits, Meri, Jacqui, Rob, Kieran and Michael heading south east, also across the lagoon, to the site of the Charles Eaton.

The Charles Eaton was a 313 ton, three masted, wooden barque under the command of Captain J.G. Moore when it was wrecked on a speculative voyage to India in 1834. On board the vessel were Captain William D’Oyley of the Bengal Artillery, his young family and several other passengers. The vessel struck the eastern edge of the Great Detached Reef and some of the crew deserted in the only serviceable boat leaving the passengers and remaining crew stranded on the wreck. The survivors built a small raft on which they successfully sailed to the mainland but unfortunately they encountered a group of Aboriginal people who killed all the survivors except for a young crewman called John Ireland and two year old William D’Oyley – they were subsequently rescued two years later by Captain Lewis of the schooner Isabella – by which time young D’Oyley had become completely assimilated into an Aboriginal family and could no longer speak English.

With Bungee searching the reef from overhead we sent out Xanthe, Rob, Meri, Frits, Jacqui, Kieran and Michael to commence surveying the buoyed shipwrecks starting with the one on the northern arm of Great Detached Reef.
This site consisted of a single iron anchor out on the edge of the reef on the other side of the surf break, two large mid-19th century iron anchors – one lying flat on the seabed the other picked into the reef top some 120 metres in from the edge of the reef. Surrounding these substantial anchors (4.0m long by 2.8m wide) are several lines of stud link anchor chain running in a north-westerly direction from the edge of the reef across the reef top and towards the centre of the site. Around the anchor chains are large iron concretions (an iron / sand / corrosion product matrix), a number of copper-alloy fastenings, copper-alloy sheathing (a metal coating used to protect the lower hull of timber sailing vessels from fouling and marine borers).

Scattered forward of the two anchors are several composite piles of chain, stone ballast and iron knees and rigging components – the largest mound being some 5.0 metres long, 2.0 metres wide and 1.5m high.
After leaving Pandora Entrance the expedition vessel Silentworld II, ably skippered by Michael Gooding from the Silentworld Foundation, motored down the outside of the Great Barrier Reef before coming abreast of the Raine Island Entrance – marked by its famous 14-metre high stone navigational tower and shipwrecked sailors’ refuge built on the Island by convict stone mason in 1844. The Island marks the confluence of the Inner and Outer Routes through the Great Barrier Reef and the reefs bordering the northern and southern entrances have been the location of a number of shipwrecks – with Great Detached Reef – having at least 15 known wreck occurrences.

After passing Raine Island we motored around the northern arm of Great Detached and entered the protected anchorage on the south-western side of the Reef almost directly opposite an iron fluke that was protruding above the gentle surf breaking on the northern side of the arm.
After motoring overnight the Silentworld Foundation’s Research Vessel Silentworld II arrived offshore from Moulter Cay (Entrance Cay) some four nautical miles south of the wreck site of HMS Pandora.
In 1790 the three masted, wooden, 24 gun, Porcupine class frigate HMS Pandora sailed from England to Tahiti in the South Pacific in pursuit of HMAV Bounty and its infamous mutineers led by Fletcher Christian. After capturing some of the mutineers, the Pandora searched the Pacific, visiting the Solomon, Rotuma, Union, Samoa, Palmerston, Society and Cook Islands before returning to England, via the Torres Strait when it was wrecked in an entrance through the Great Barrier Reef that beats its name.

The survivors sailed in open boats from the Barrier Reef to Java and eventually returned to England, where the surviving mutineers were brought to trial. The wreck site was re-discovered by divers – with the assistance of the Royal Australian Air Force – in 1977.
Bungee and his helicopter left early this morning after a successful day yesterday looking for aircraft wrecks along the coast, whilst we waved Bungee off, the crew prepared Silentworld II for sea – destination Eel Reef.
Vessel arrived off Eel Reef two hours later and the two dive tenders were lowered off the top deck, filled with divers and equipment, and then despatched from Silentworld II to mag and dive the reefs we did nit survey the last time we were here.

Conditions were perfect – well a little too perfect – the sea was so calm we had trouble seeing the edge of the reefs and coral bommies –which can usually be seen by the breaking of the sea over them.
After closing down the work on the Frederick wrecksite we have decided to shift our attentions further north and have another look for the Morning Star (1814) – wrecked off Eel Reef near Quoin Island.
However first things first – on the way up we have arranged to meet up with well-known Queensland diver and documentary film maker Ben Cropp. Ben has been diving and finding shipwrecks in far northern Queensland for more than forty years – he found the Fergusson shipwreck on Ferguson Reef way back in the late 1970s and was also one of the divers who found HMS Pandora.

Ben and his boat Freedom are anchored up behind the back of Night Island about 20 nautical miles to the north of us and conveniently on the way to Eel Reef. Ben has asked us to help him in his hunt for the ship Swiftsure which was wrecked in the vicinity of Night Island in 1829 just after it had rescued the crew of HMCS Mermaid which had been wrecked on Flora Reef near Cairns just a few weeks before and re-discovered by the Silentworld Foundation and the Australian National Maritime Museum in 2009.
Conditions are remaining perfect for diving with the weather forecast predicting very light easterly winds for the next five to six days – with such great conditions all dive-tenders were away early from the stern of SWII heading for Wreck Bay – a few kilometres south and east of the anchorage.
The two Silentworld Foundation dive-tenders arrived on site and whilst the smaller Carib checked out the shallows and beaches for any crocodile activity the dive teams got ready to enter the water from the larger Hydra-sport.

Peter from GBRMPA and I entered the water first – down one of the buoys marking the larger of the magnetic anomalies – and we commenced a circular sweep of the seabed using the metal detectors searching the shallow sand and weed patches, areas of broken coral and larger intact expanses of staghorn and plate coral for any signs of the Frederick.
On Monday afternoon expedition team members from the Silentworld Foundation, the Great Barrier Reef Marine Park Authority (GBRMPA) and the Museum flew into Lizard Island 80 nautical miles north of Cairns to continue their search for the wreck of the Indian-built opium trader Morning Star (1814) and the Javanese-built merchant vessel Frederick (1818).
After carrying out the usual pre-trip safety checks (diving and fitness) the team departed Lizard Island on Monday evening heading for Wreck Bay off Stanley Island in the Flinders Group.
Tuesday 19 November 2013
After motoring overnight on board the expedition vessel Silentworld 2 the team arrived off Wreck Bay to be greeted by perfect diving conditions – with no wind and almost pancake flat seas.
In no time at all – with the dive tenders fuelled, the dive, survey and safety equipment checked and loaded and the divers briefed – the team was off to search and hopefully locate the remains of the Frederick which was driven onto a coral reef at the head of Wreck Bay in 1818.
In April the Silentworld Foundation and the Australian National Maritime Museum returned from Ferguson Reef with a whole heap of information from the wreck-site of the Indian-built troopship Fergusson lost on Ferguson Reef in 1841 whilst on a passage to India from Sydney.
The team also brought back stacks of remote sensing data associated with our search for two other elusive shipwrecks associated with that early trade. The Indian built opium trader Morning Star lost south of Forbes Island in 1814 and the Javanese built trading ship Frederick wrecked of Stanley Island in 1818.

The Morning Star was a two masted, teak hulled, possible copper sheathed and fastened brig of 135 tons built by J. Scott and Company of Fort Gloster, India in 1813 for Lackersteen and Co and registered in Calcutta, India. (Parsons, 2003) Additional information, supplied from the Report of ships and vessels cleared outwards from Port Jackson in His Majesty’s Colony of New Wales 1/07/1814 – 30/09/1814 indicates the small vessel carried at least 8 cannon and a relatively large crew of 36 – hall marks of either a privateer or a vessel involved in the shipment of a valuable cargo – such as tea or opium.
April Fool’s Day – The wind has been steadily increasing overnight and some of the team – including Frits and Lee – have abandoned Hellraiser 2 to seek more comfortable berths on board the much larger SWII which does not bounce around so much in the increasing swell.
Plans for the day are much the same as yesterday, with the exception that the team will be joined by Steve and Sparra in Hellraiser 2 which – because we are operating more than eight miles away from the main vessel SWII – will act as a temporary rest stop for the teams working out of the smaller dive tenders.
Four teams on and in the water today – Frits and John ‘magging’ in Maggie; Gil, Greg, Lee and Freddy diving anomalies in Caribe; Xanthe, Jacqui, Andrew, Rick, Glen and I ‘magging’ and diving in the Hydro-sport; and Sparra, Steve and Grant on Hellraiser 2.
Woke up this morning to a very empty anchorage at the back of Ferguson Reef – with Silentworld II (SWII) and the Hydro-sport dive tender having left for Portland Roads at 0330 this morning – leaving a much reduced crew (Xanthe, Andrew, Grant, Freddy and I) on board Hellraiser 2 to check out the last remaining anomalies and take the last measurements before cleaning up the site and sailing westward to meet the larger team at Eel Reef, and hopefully the wreck of the Indian-built opium clipper Morning Star wrecked three miles south west of Quoin Island in 1814.
With a much smaller team to get ready we got to the outer edge of Ferguson Reef and the wrecksite of the Ferguson in plenty of time for the high water slack.
Xanthe, Grant and Andrew from the Silentworld Foundation and I jumped in just to the seaward of the ‘picked in’ anchor and allowed the last few minutes of the floodtide to carry us in over the reef top and along the stud link anchor chain which runs back over the top of the reef for some 200 metres before ending amongst flat plate and staghorn coral.
After a somewhat late night for the expedition team members and crew who had been waiting for the arrival of Hellraiser 2, the team members got together early the next morning to discuss the practicalities of working the ‘end of flood tide’ on the wrecksite so Xanthe could get a complete photomosaic of the site.
We decided to send a small team of divers, including Xanthe, Greg, Gil and Andrew, over to the site just before the ‘end of flood’ at 0700 so that Xanthe would have enough water depth to complete the photomosaic. Just in case, Freddy and Kieran would act as stand-by divers so that the in-water divers could be pulled out of the water if the ebb-tide came in earlier than expected.
Luckily conditions on site were perfect with the strong south-easterly (wind) holding up the ebbing tide long enough for the photomosaic to be completed without incident.
In the afternoon we planned for Frits and John to mag the northern part of the lagoon, have Andrew and Grant record the features of the carronades (cannon) on site, have Gil and Greg record the dimensions of all the various bits on the anchor chain, and Jacqui and I would record the knee and bilge pump dimensions. Unfortunately and unexpectedly the tides refused to cooperate – although for the last couple of days, the tides were behaving relatively normally with gaps of approximately 6 hours between High and Low tide – today the ebb tide was more prolonged, possible due to the effect of the New Moon. This meant the dive tender and Maggie (the shallow drafted magnetometer boat) were unable to get over the western edge of the reef and onto the wreck site.
After waiting for three hours – and noticing no discernible difference in the level of the water over the reef – the team called the dive and returned to Silentworld II.
This morning the weather conditions appeared to be improving on yesterday’s so we sent off four teams to work on the Ferguson site.
Team One consisting of Frits and John dove on a series of magnetic anomalies off the south western side of Ferguson Reef, Gil and Greg in Team Two measured up an anchor at the northern part of the site, Peter and Jacqui in Team Three measured a ‘flat’ anchor and Grant and Andrew in Team Four measured an anchor in the surf zone. Whilst all this was going on Xanthe took photographs of the work in progress and I monitored the work from the surface whilst taking part in an open classroom discussion via telephone through the DART virtual excursion program of the NSW Department of Education.
As the teams returned from the wrecksite the whole area was struck by a series of rain squalls drenching everyone – well at least it saved us the job of washing the dive gear.
After lunch, sea conditions appeared to have quietened down once again and in almost perfect conditions we set off to dive on the site. Gil, Greg and I went to measure the length of a stud link anchor chain that was attached to a ‘picked in’ anchor. Peter and Jacqui jumped in to measure up the various iron knees, assisted by Andrew, John and Frits armed with metal detectors they commenced a non-disturbance metal detector survey of the site to find out ‘what lies beneath’.

Over the last few days the weather conditions on site have started to deteriorate as as the effects of a new monsoonal trough comes into play.

With a substantial surf breaking over the southern and eastern edges of Ferguson Reef and with limited space in the boats we decided to send only single teams of snorkelers onto the reef-top searching for the magnetometer hits that John and Frits had detected on the previous day. Continue reading →
