Arrangements for transferring survivors will be made by PNG authorities.

1640 - "Our hearts go out to those affected by the sinking of the MV Rabaul Queen," Australian Foreign Minister Kevin Rudd says. “I spoke to my counterpart, PNG Foreign Minister Ano Pala, to inform him that Australia stands ready to offer all necessary assistance."

1615 – The ABC reports that 193 survivors have now been rescued by 8 vessels on the scene supported by 3 helicopters.  More people are visible in life rafts. The passengers were mainly students and teachers returning for the start of the new school year.  Search and rescue planes are now in operation over the site. Weather conditions are described as reasonable.

1610 - Australian prime minister Julia Gillard says there is likely to be a very high death toll from the sinking of the Rabaul Queen. "There has been a boat go down in PNG with, as we understand it, 350 people on board," Ms Gillard told reporters in Melbourne. "This is obviously a major tragedy. We have been asked to provide assistance to PNG and we are providing assistance to PNG."

1600 - [Maritime Matters] The 1983-built passenger/cargo ship MV Rabaul Queen, with a gross tonnage 259 flagged in Papua New Guinea is believed to have sunk in bad weather with as many as 350 people on board. The operators Star Ships said it lost contact with the vessel at about 6AM on Thursday while enroute between Kimbe and Lae. A distress signal was sent by the ship.

PNG’s National Maritime Safety Authority said the ship had capsized but it was awaiting more details from officials on the site. “We don’t have any accurate information as yet, a search and rescue team went out early this morning but they haven’t got back to us yet,” a spokeswoman said.

Star Ships added that some survivors have been found, one report said that at least 28 passengers has been rescued [now confirmed as 50], while many more were in the water in life jackets at this time.

1545 - It is reported that 28 people have been rescued from the water.  These people are now aboard one vessel. Authorities are not able to confirm how many people were on the Rabaul Queen other than to say the complement was "probably around 300".

1430 - The Australian Maritime Safety Authority (AMSA) is currently providing assistance to the Papua New Guinea Maritime Rescue Coordination Centre which is coordinating a rescue involving a passenger vessel, the MV Rabaul Queen.

The vessel is reported to have sunk approximately 16 km off Finschhafen while on a voyage from Kimbe to Lae. There are believed to be 350 people on board.

At 07:25am AEDT today, AMSA’s Rescue Coordination Centre received an initial satellite detection of a distress beacon belonging to the passenger vessel MV Rabaul Queen. This information was immediately communicated to the PNG Maritime Rescue Coordination Centre.

AMSA consequently broadcast a message to shipping in the area and requested shipping to advise of their ability to respond and estimated time of arrival. A number of vessels responded and six merchant vessels are currently on scene, four of which are recovering survivors.

In addition, three local helicopters are on scene searching for survivors and relaying location details to the vessels.

The master of one of the vessels, the Mol Summer, has been appointed on scene coordinator and has reported that approximately 50 people have been rescued so far.

AMSA’s dedicated search and rescue Dornier aircraft based in Cairns has now arrived on scene. The Dornier has multiple life rafts on board and the capability to drop them to survivors in the water.

Further fixed wing aviation search assets have also been tasked by AMSA, including an Australian Defence Force PC3 Orion aircraft (due on scene at approximately 4pm AEDT) and AMSA’s Darwin-based Dornier (due on scene later this afternoon). Both of these assets are capable of aerial stores delivery including life rafts.

AMSA is further assisting the PNG Maritime Rescue Coordination Centre by providing search area planning and drift modelling.

AMSA and the Australian Government Crisis Coordination Centre are working closely with the Department of Foreign Affairs and Trade and the Australian High Commission in Port Moresby.
