They were seen with a naked eye, among them a wooden pallet, within a radius of five kilometres in the southern Indian Ocean, the agency said.

The aircraft dropped a marker buoy to track the movement of the material and a merchant ship has been tasked to locate and identify it. The Royal Australian Air Force, the Royal New Zealand Air Force and two chartered civil aircraft supported Saturday’s search for wreckage.

Since ASMA assumed co-ordination of the search on Monday more than 150 hours of air time has been committed by the air crews to the task.

The search has been split into two areas within the same proximity, covering 59,000 square kilometres. The Royal Australian Navy's HMAS Success and two merchant ships are also in the search area.

Mr Abbott said four more aircraft - two Chinese and two Japanese planes - would join the Indian Ocean search on Sunday.

The new Chinese satellite imagery suggests at least one large object, Mr Abbott said on Sunday. "Yesterday one of our civilian search aircraft got visuals of a number of objects in a fairly small area in the overall Australian search zone," he told reporters.

A wooden pallet was among the items, he said. "Obviously before we can be too specific about what it might be, we need to recover this material. It's still too early to be definite," he said. Mr Abbott says there is increasing hope that authorities are on the road to discovering what happened to the ill-fated jet. The floating object captured in the Chinese satellite image falls into Australia’s search area. ASMA said this information, which was provided to Australia on Saturday, would be taken into account during Sunday's search.

James Cook University marine scientist Rob Beaman said it was "unusual" for there to be marine debris in the southern Indian Ocean as large as the object captured in Chinese satellite imagery. "The scale is important and until we see it up close we can’t discount that it might be from the crash site," Dr Beaman said. "Even big freight containers, the biggest ones, are not as long as the object in the images. The scale is pretty significant." Another ocean expert, Charitha Pattiaratchi from the University of Western Australia, said the search area was outside normal shipping lanes and distant from circular currents in which waste often accumulates. He said if the objects sighted were recovered experts could determine how the currents had moved them and where the plane may have crashed into the ocean.

The debris could also have been moved into the search area from currents off South Africa or South America, he said. NASA to help NASA will check satellite data and point space-based imaging equipment at the search area to assist with the search for the missingplane, CNN reports. The Earth-Observing-1 (EO-1) satellite and the ISERV camera on the International Space Station would be able to provide images with a resolution that could be used to identify objects of about 30 metres or larger.
