Background
7 The Department of Immigration and Citizenship ("DIAC") is a Department of the Commonwealth of Australia. At all times relevant to these proceedings prior to 30 January 2007 DIAC was known as the Department of Immigration and Multicultural Affairs.
8 DIAC was and remains charged with the responsibility for managing immigration and border control through the Torres Strait. Movement Monitoring Officers ("MMOs") were recruited by DIAC to assist in patrolling the reefs and islands of the region. The MMOs used immigration response vessels ("IRVs") to conduct such patrols.
9 Towards the end of 2002 Mr Garry Chaston was appointed as DIAC's regional manager on Thursday Island. In February 2004 Mr Chaston put a business case to DIAC to replace the existing fleet of vessels with new IRVs. Expenditure for the new IRVs was approved. The procurement of the new IRVs remained the primary responsibility of Mr Chaston but he was assisted by Mr Paul Nemes, DIAC's senior contract adviser. Mr Chaston also consulted Mr Greg Hellessey who was a qualified marine engineer, the MMOs and a range of other government agencies.
10 After advertising, eight tenders were received. Criteria for assessment of the tenders were settled by Mr Chaston and Mr Nemes, and a team was established to evaluate each tender received. Subsequently, Subsee Explorer Pty Ltd ("Subsee") was contracted for the supply of the six IRVs. The contract with Subsee contained specific descriptions of the proposed vessels, the equipment to be fitted, the standards of construction, and the certificates required to accompany the vessels.
11 Significantly, the contract stipulated that the vessels be supplied to the certified requirements of the Uniform Shipping Laws Code ("USL Code"), Class 2C, and comply with the Australian Standard ("AS") 1799 and AS 1665. However as subsequently became clear, a prototype vessel constructed by Subsee did not meet these requirements and this omission was not disclosed or discovered at the time of the sea trials. Further, no reference to the omission was made in the modifications specified.
12 The contract also stipulated that Subsee was to provide six different certificates for each of the IRVs. Only one certificate was provided, a certificate of flotation. The positive flotation statement (issued by a Mr Radke, the principal of Subsee) was a document declaring that the vessel when filled with water would remain afloat in an upright position while carrying its normal operational equipment and six passengers. The other five certificates, including certificates that the vessels were to class 2C survey standard, and confirmation they complied with AS 1799 and AS 1665, were never provided to DIAC.
13 Following acceptance of the prototype trial with specified modifications, the remaining five IRVs were completed by Subsee in early August 2005. These vessels were subsequently delivered to Thursday Island on 21 and 22 August 2005.
14 The IRVs were of a centre console configuration and were constructed of aluminium plate aluminium alloy. They had a designed overall length of 6.65 metres, a designed measured length of 5.90 metres, a breadth of 2.15 metres, and a draft of 0.45 metres. The vessels were designed to carry up to six people or 510 kilograms.
15 The navigation equipment on board consisted of a magnetic compass and navigation lights. The safety equipment included a 121.5/243 MHz analogue emergency positioning indicating radio beacon ("EPIRB"), life-jackets, flares, a fire extinguisher, bailing buckets, first-aid kit, tool-kit, paddles and two hand-held torches. The communication equipment consisted of a hand-held satellite/CDMA telephone and a "hands-free" system for the telephone.
16 As "Commonwealth ships" within the meaning of the Navigation Act 1912 (Cth), the IRVs were not required to be surveyed. Instead, the operator of Commonwealth vessels under seven metres in length could request the Chief Marine Surveyor to issue a letter of survey acknowledging that the vessel met specific criteria. The letter would be subject to the provision of assurances to the Chief Marine Surveyor about the construction, equipment and area of operation of the vessel.
17 On 24 August 2005, Mr Chaston applied for a letter of survey for the IRVs by writing a letter to the Australian Maritime Safety Authority ("AMSA") declaring:
(a) he was the officer responsible for the safe operation of the six IRVs;
(b) the IRVs were built to AS 1799;
(c) the vessels were suitable for their intended operations and were in a seaworthy condition prior to each operation;
(d) a planned maintenance program was in place;
(e) a risk assessment was undertaken prior to each operation; and
(f) the vessel's area of operation was the partially smooth waters of the Torres Strait.
18 On 2 September 2005, AMSA issued a letter of survey for the six IRVs.
19 DIAC had standard operating procedures ("SOPS") for the IRVs containing instructions for the MMOs, including administrative processes and operational information. These procedures required the submission of a "tasking request form" prior to operations and a "post-patrol report" after each patrol. In relation to the operation of the IRVs, the SOPs included information relating to limits of operation in terms of area, time of day, duration, weather and crew qualifications.
20 An annual training workshop for the MMOs was arranged to be held on Saibai Island from 8 to 13 October 2005. Three of the IRVs, including the Malu Sara, were to travel to the island for the workshop. The Malu Sara left Badu Island for Saibai Island on 8 October 2005, a journey of 58 nautical miles. On Wednesday 12 October 2005, the Malu Sara was used in two training patrols. In the first, the outboard motor stopped without apparent reason but was restarted and no further problems were reported. In the second, a significant quantity of water entered the cockpit through the scuppers in the cockpit transom while the vessel was anchored with five persons on board.
21 After the patrol was completed, the crew reported to Mr Chaston that the vessel appeared to be sitting low at the stern. Mr Chaston inspected the vessel while it remained in the water and told the crew to inspect the boat overnight to ensure the problem did not reoccur. No further action was taken.
22 On 14 October 2005, the Malu Sara left Saibai Island shortly before 12.30 pm carrying two employees of the respondent and three members of the public. Mr Baira was the skipper. He called DIAC's Thursday Island office (then staffed by Mr Jerry Stephen) at 12.22 pm to advise of the departure and arranged a subsequent call when he reached Turnagain Island. At 2.08 pm he made the scheduled call reporting that he was near Turnagain Island, and arranged to call again when near Mabuiag Island.
23 Between 3.54 pm and 3.57 pm Mr Baira rang the office on four occasions telling Mr Stephen he was "a bit lost in a fog" but that all onboard were well and he had plenty of fuel. Mr Stephen advised Mr Baira to steer at 160 degrees or 170 degrees to get into the lee of the reefs and towards Mabuiag Island.
24 Failed attempts by Mr Baira to call Mr Stephen were made at 4.25 pm, 5.50 pm and 6.05 pm. At 6.22 pm Mr Baira rang Mr Stephen reporting that he had sighted an island but was still lost. Mr Stephen told Mr Baira that he should activate his EPIRB to fix his position if he could not locate the island. There was further contact at 7.34 pm when Mr Stephen and Mr Baira had further discussions about activating the EPIRB.
25 At about 7.15 pm the Queensland Police Service at Thursday Island was notified by Mr Chaston that the Malu Sara was overdue and seemingly lost. At 7.40 pm Sergeant Warren Flegg, an officer from the Queensland Water Police on Thursday Island, began co-ordinating the search. The Australian Search and Rescue organisation ("AusSAR") in Canberra was contacted at 8.11 pm.
26 Some telephone contact was maintained with Mr Baira between about 7.45 pm and 9.30 pm. About 10 of 20 attempted calls were successful and the EPIRB was transmitting. Based on the satellite information, AusSAR established an approximate position of the vessel at approximately 10.00 pm and relayed this to Mr Stephen asking that he advise Mr Baira to head due east towards Mabuiag Island. Thereafter, telephone contact with the vessel was difficult to establish.
27 At about 1.37 am on 15 October 2005 Mr Baira informed Sergeant Flegg that the vessel was at anchor but was out of oil. At 2.15 am Mr Baira told Mr Stephen the vessel was taking on water and was sinking. No further contact with the vessel could be established.
28 At approximately 2.30 am, Sergeant Flegg contacted the Thursday Island Volunteer Marine Rescue ("VMR") requesting a search vessel be sent out. At about 4.15 am, the "Pedro Stephen" left Thursday Island with three crew onboard. Shortly before 6.00 am the IRV from Mabuiag Island also joined the search.
29 Intensive air and sea searches ensued in the following days. At approximately 10.30 am on 15 October 2005 the vessel's EPIRB was found with a 1.5m length of its lanyard attached. No other debris has been recovered.
30 At about 2.30 pm on 16 October 2005 a fixed wing aircraft sighted a person in the water but despite attempts, the person was unable to be recovered. On 26 October 2005, a body subsequently identified as being that of Ms Flora Enosa was found by Indonesian fisherman about 50 miles west of the vessel's last known position. No other bodies have been recovered.
31 It is not in dispute that the telephone on the vessel would not have functioned in the water. As the telephone on the vessel was still accessing the network until 3.57 am it is estimated the vessel finally sank at some time around or after 4.00 am on 15 October 2005.
32 Upon the search being scaled back, an investigation into the incident was instigated by DIAC. The Entry Policy and Procedures Branch issued a report dated 3 November 2005 which found a combination of factors had contributed to the incident. The use of the remaining IRVs was suspended on 15 or 16 October 2005.
