The US and Royal Australian Navies are set to begin Exercise Talisman Sabre 2015, in a bid to test and improve interoperability between both the countries.
The exercise, which is conducted every two years, is designed to incorporate activities at sea, on land, and in the air.
This year, the training activities will be conducted across both North East Queensland and the Northern Territory.
Royal Australian Navy ships have begun to arrive in Darwin to take part in the exercise, including the Anzac class frigate, HMAS Perth.
HMAS Perth commanding officer captain Ivan Ingham said: "This is a terrific exercise in terms of its complexity and size."
"We really value the opportunity to work with the United States and the US Marines in an amphibious construct, both to test our interoperability and also our high end warfighting skills."
The exercise will see the participation of approximately 30,000 sailors and soldiers, as well as airmen and women.
In addition, different types of marine ships will be part of the event across the exercise region.
The Australian Navy's new MH-60R Romeo Seahawk Helicopter abroad HMAS Perth will also be part of the exercise.
Recently, the US Navy and Marine Corps personnel, along with Armed Forces of the Philippines (AFP), completed the 21st annual cooperation afloat readiness and training (CARAT) Philippines exercise series.
The US Navy's USS Fort Worth littoral combat ship (LCS 3) participated in training events, including tactical combat casualty care (TCCC), visit, board, search and seizure (VBSS), gunnery exercises, manoeuvring in formation, air defence exercises, and a search and rescue drill.
