The frigate and aircraft have now returned to their homeport of Fleet Base West in Western Australia, having completed an extended deployment that included a critical search and rescue effort.

The Anzac class frigate departed Australia with HMAS Sirius in early March for a deployment throughout Southeast Asia and the Northeast Indian Ocean.

Originally due to return to Fleet Base West on May 14, the ship was called upon to conduct a search and rescue in the southern Indian Ocean.

After a RAAF P-8A Poseidon aircraft assisted in locating a commercial fishing vessel in trouble off the WA coast, Anzac sailed approximately 670 nautical miles west of Perth to provide support in the rescue of the Indonesian fishermen who became stranded on their sinking vessel.

Japanese fishing vessel Fukuseki Maru 15 had rescued the fishermen from their stricken vessel, before being transferred to Anzac and offered medical assistance and accommodation on-board Anzac.

One fisherman was transported to a Perth hospital by Anzac's MH-60R maritime combat helicopter, callsign "Berserker" from 816 Squadron at Albatross, for urgent care.

Anzac delivered the other 19 fishermen to their homeport in Bali last Friday.

Chief of Joint Operations, Lieutenant General Greg Bilton, said Anzac's quick transition to the search and rescue task was a testament to the commitment of the professionalism of the ship's company.

"I would like to personally thank the ship's company for their commitment and focus throughout this deployment, particularly after being recalled with their homeport in sight after almost three months at sea." Lieutenant General Bilton said.

"HMAS Anzac had been focussed on our long-standing program of international engagements with regional partners. This included bilateral and multilateral activities with Brunei, Canada, France, India, Indonesia, Japan, Malaysia, Singapore and the United States."

Anzac's Commanding Officer, Commander Brendan Horn, said the navy-to-navy skills development during the deployment had prepared Anzac well to aid the Indonesian fishermen.

"While deployed, we practiced and refined key mariner skills with other nations, so when we got the call to assist we were ready to respond," CMDR Horn said.

"We knew there were people in distress and everyone understood that assisting them in any way we could was the absolute priority.

"The men and women of Anzac are now grateful to be home with their loved ones again and we are very grateful for their support over the past two months - we couldn't have done this without them."

COVID-19 safe protocols were implemented in the transport of the Indonesian fishermen and Anzac has been granted approval to return to Western Australia.
