The long-term future of the navy's fleet of MRH-90's based at HMAS Albatross is up in the air, with Defence remaining tight-lipped about the future of the helicopters.
Defence said no decision had been made on the future of the MRH-90 or about which logistics helicopters it would acquire.
A Defence spokesperson said in a statement that with the increase in amphibious and maritime support ships there will be a commensurate growth in the number of aircraft used by navy for maritime support.
"Under the new logistics helicopter project, Defence will rationalise the type of helicopters to be utilised in the maritime support and logistics role to better meet navy's requirements," a spokesperson said.
"This rationalisation will provide opportunities for increased organisational efficiencies and improved logistics support to the growing amphibious and support ship fleet.
"No decision has yet been made on the aircraft type. This decision will inform future plans for operation of MR-H90 in navy."
During the 2019-2020 summer bushfires the MRH-90 played an important role delivering supplies, medical assistance, evacuations and providing support services to fire-affected communities
The MRH-90 helicopter was first introduced to HMAS Alabtross in 2013 with two being placed into 808 squadron.
Since the navy replaced its Sea King fleet and the Army's Black Hawks with the MRH-90 there has been issues with the helicopter.
The MRH-90 helicopters were grounded in July 2019 for over a month after a tail rotor vibration was detected during a flight.
It was later revealed Defence had known about issues with a small component on the tail rotor since October 2018.
Obtained by the ABC under Freedom of Information, the quarterly performance report from the Department of Defence's Capability and Sustainment Group, listed two major projects, the ADF's MRH-90 helicopters and the Deployable Defence Air Traffic Management and Control System as areas of concern.
Although much of the detail has been redacted on "national security", the report said Australia was spending $3.5 billion on 47 new MRH-90s.
Defence said there were concerns over the delivery and service release of the enhance cargo hook system on the MRH-90s but rebuked claims in the ABC report that the aircraft had issues with the auxiliary power unit on board, which limits the fleets' capability because it cannot shut down its main engines due to problems with the power unit.
