No time limit will be imposed on the search for MH370 because the world deserves to know what happened, Australian premier Tony Abbott said Monday, as a ship equipped to locate the plane's "black box" prepared to set sail.

The hunt for physical evidence that the Malaysia Airlines jet crashed in the Indian Ocean more than three weeks ago has turned up nothing, despite a massive operation involving seven countries and repeated sightings of suspected debris.

Asylum-seekers arriving in Australia on unauthorised boats will no longer be granted free advice on immigration matters, the government said Monday.

Scrapping the scheme that helped asylum-seekers complete visa applications and gave them advice on complex immigration matters is expected to save Aus$100 million (U.S.$93 million) over four years.

A new search area failed to yield an immediate breakthrough in the hunt for ill-fated Flight MH370 on Sunday, as Australia appointed its former military chief to help coordinate the operation in the Indian Ocean.

Debris spotted by aircraft and then picked up by ships combing the new search zone proved not to be from the Malaysian Airlines' Boeing 777, the Australian Maritime Safety Authority (AMSA) said.

Planes and ships raced Friday to a fresh search zone after a "credible new lead" that Malaysia Airlines Flight MH370 was flying faster than first thought before it plunged into the remote Indian Ocean.

Ten aircraft from six countries -- Australia, China, Japan, New Zealand, South Korea and the United States -- altered their flight paths to an area 1,100 kilometers (685 miles) northeast of where they have been looking for a week, far off western Australia.

Even if searchers are able to miraculously pluck Malaysia Airlines flight 370's "black box" from the depths of the vast Indian Ocean, experts say it may not solve one of aviation's greatest mysteries.

Planes, ships and state-of-the-art tracking equipment are hunting for any trace of the passenger jet, which Malaysia said crashed in the forbidding waters after veering far from its intended course.

Wild weather halted the search Tuesday for wreckage from the Malaysia Airlines jet that crashed into the Indian Ocean, frustrating attempts to determine why it veered off course and bring closure to grieving relatives.

The air and sea mission for MH370 was suspended for the day due to gale force winds, driving rain and huge waves, said the Australian Maritime Safety Authority which is coordinating the multinational hunt southwest of Perth.

The sighting of a wooden pallet and other debris that may be linked to a Malaysian passenger jet raised hopes Sunday of a breakthrough in the international search for the missing plane.

The sense that the hunt was finally on the right track after more than two weeks of false leads and dead ends was reinforced by new French satellite data indicating floating objects in the southern search area.

A light aircraft used for skydiving crashed in an airfield in eastern Australia on Saturday and burst into flames, killing all five people on board, police said.

The plane veered left shortly after taking off from the Caboolture airstrip, 50 kilometers (31 miles) north of Brisbane on Australia's east coast, before plunging to the ground.

China released Saturday a new satellite image of a large floating object possibly linked to missing Malaysian Flight MH370, boosting search efforts as anger with the pace of the operation boiled over among Chinese relatives in Beijing.

The grainy photo taken on March 18 released by the State Administration of Science Technology and Industry showed an object measuring 22.5 meters by 13 meters (74 by 43 feet) in the southern Indian Ocean.

Spotter planes on Friday scoured a remote, storm-tossed stretch of the Indian Ocean for wreckage from a Malaysian jet, as Chinese relatives of the missing passengers clashed with Malaysian officials over their handling of the search operation.

The Australian and U.S. aircraft criss-crossed an isolated section of ocean 2,500 kilometers (1,500 miles) southwest of Perth, looking for two floating objects that had shown up on grainy satellite photos taken several days before.
