Defence sources said the purchase of lifeboats was designed to thwart the tactic of using rickety fishing vessels and sabotaging them at sea, leaving Australian border protection authorities no choice but to rescue them. Illustration: Matt Golding When a boat is intercepted, the asylum-seekers could be transferred on to the lifeboats close to Indonesian waters with enough fuel and supplies to reach land. The high-visibility, engine-powered lifeboats, which have roofs, can carry dozens of passengers, and food and water for at least a week. In a stand-off at sea in November, Indonesia refused to take back an asylum-seeker vessel on the grounds that it was unseaworthy.

Immigration Minister Scott Morrison refused to confirm or deny the purchase of the lifeboats, citing the need to "protect the security of our operations".

''I can't make anything of the [lifeboats] idea because Australians are being left to guess at what the Australian government's doing in our name,'' he told ABC Radio on Wednesday. ''That is not acceptable.''Greens senator Sarah Hanson-Young said the lifeboat reports showed the government's asylum-seeker policy had failed.

''I think this just shows what tatters Scott Morrison and Tony Abbott's policy is in,'' Senator Hanson-Young told ABC Radio. ''First we heard they were going to stop the boats, then they said we'll buy back the boats, now they're going to start giving away boats.'' The Abbott government also maintained its silence over claims that Australia had turned back at least one asylum-seeker boat to Indonesia in recent weeks, in a move that could increase tensions. A Defence source confirmed to Fairfax Media reports in the Indonesian press that a boat had been turned back. The source said the frigate HMAS Stuart carried out the turn-back in the past week. The asylum seekers aboard the boat were given life jackets and communications equipment.

Indonesian Foreign Minister Marty Natalegawa, while refusing to comment on any turn-backs, repeated Jakarta’s general condemnation of the policy on Tuesday. "The policy itself, the so-called tow-back (policy) – let me put it once more on the record: our rejection of such policy is because it’s not a conducive and comprehensive solution to the issue," he said. Indonesian water police told Fairfax Media that two boats had been turned back, one on Monday and one on December 19. The sources said a boat turned back on Monday carried 45 passengers, 36 male and nine female, mostly from Africa though with several from the Middle East. Another boat turned back just before Christmas carried 48 asylum seekers from Somalia, Sudan, Eritrea and Iran. Both were found at Rote Island, Indonesia’s southernmost point. Rote police chief Hidayat told Fairfax Media: "The asylum seekers’ boat was stranded near a small village called Lengu Tepu, around 4am yesterday ... They were rescued by the locals, because the boat engines were dead. The boat now is a wreckage, near some reefs."

Loading Dr Natalegawa said he believed relations between Australia and Indonesia would return to normal following stoushes over asylum seekers and revelations that Australian spies targeted the phones of senior Indonesian leaders. With Karuni Rompies, Amilia Rosa, Judith Ireland, AAP
