The remains of the third and final United States marine, who was killed when a military aircraft crashed off the central Queensland coast, have been recovered.
The tilt-rotor MV-22 Osprey with 26 people on board, plunged into the sea at Shoalwater Bay, near Rockhampton, during a scheduled military exercise on August 5.
Three marines, Captain Benjamin Cross, Corporal Nathaniel Ordway and Lance Corporal Ruben Velasco, were killed in the crash.
Australia's HMAS Melville located the wreckage two days later and a Royal Australian Navy dive clearance team worked with US forces to finalise recovery plans.
Cpl Ordway and Lance Cpl Velasco's remains were recovered, transferred to Hickham Air Force Base in Hawaii and are being sent on to their families.
Cpt Cross' remains have now been recovered and will also be sent to Hawaii.
"From Hickam, fallen service members are prepared for transport to their final destination as determined by the families," 31st Marine Expeditionary Unit First Lieutenant Joseph Butterfield said in a statement on Friday.
"A solemn, dignified transfer of remains continues to be the priority as our fallen Marines are returned to their families."
The US Marines again thanked the HMAS Melville and Australian dive crews for their help in the recovery operation.
The US lead salvage of the Osprey wreckage is ongoing.
