The latest search operational report says over 24,000 square kilometres (40 per cent) of the priority search area of 60,000 square kilometres have now been searched.
Four vessels are currently involved in the underwater search. These vessels employ a range of equipment including side scan sonar, multi-beam echo sounders and video cameras to locate and identify aircraft debris.
Assuming no other significant delays with vessels, equipment or from the weather, the current underwater search is expected to be completed by around May 2015.
In addition to locating the aircraft, the underwater search aims to map the MH370 debris field in order to identify and prioritise the recovery of specific aircraft components, including flight recorders.
The MH370 disappeared on 8 March 2014, while flying from Kuala Lumpur to Beijing with 239 passengers and crew on board.
