Search teams still hunting for MH370’s final resting place will go back and examine 30 sites which were previously ruled out.
The Australian Transport Safety Bureau (ATSB) said investigators will use ‘higher frequency sonar’ at the sites.
"The search for MH370 is being conducted thoroughly and to a very high standard and it is important that contacts are comprehensively investigated and considered," the ATSB told the Daily Mail.
The Southern Indian Ocean has been scoured by search teams for clues but the only physical proof so far has come from the discovery of a ‘flaperon’ wing piece which washed ashore in Reunion Island.
In the two months since then, no other debris linked to MH370 has been found.
ATSB chief Martin Dolan still remains confident they are searching in the right area and the jet will be found.
"There’s still a lot of territory to cover and still a very high prospect that we will find the aircraft there," he recently said.
