HMAS Warramunga and KD Lekir have wrapped the Malaysia-Australia Training Exercise (MASTEX) off Australia’s west coast, marking another iteration of the long-running bilateral activity.

MASTEX is a biennial exercise that brings together the Royal Australian Navy and the Royal Malaysian Navy to strengthen operational integration and cooperation.

Australia and Malaysia share a deep and enduring defence relationship built on decades of cooperation, mutual respect and aligned regional interests. 

This partnership is underpinned by the Malaysia-Australia Joint Defence Program (MAJDP), established in 1992, which continues to support people-to-people ties, training, exercise integration and operational collaboration.

Over more than two decades, MASTEX has evolved alongside the changing maritime environment. 

Commanding Officer Lekir Commander Megat Mohamed Sofwan Firdaus bin Megat Mohamad said this evolution ensured the activity remained relevant and operationally meaningful.

“Since its establishment in 2002, MASTEX has grown into a key bilateral engagement between our two navies, consistently enhancing interoperability, operational exchange and mutual trust,” Commander Megat said.

“It ensures that Malaysia and Australia can operate together smoothly, safely and effectively during maritime operations.”

The Five Power Defence Arrangements (FPDA), established in 1971, remains Australia’s only multilateral defence arrangement in South-East Asia and is central to enabling cooperative operations with Malaysia. 

'The defence of our countries is closely tied to the peace and stability of the Indian Ocean, North-East Asia and the Pacific.'

FPDA provides the framework for access, combined readiness and operational understanding, supporting exercises such as Bersama Shield, Bersama Lima and MASTEX.

Activity Commander Captain Benjamin Dalton said MASTEX was integral to maintaining a regional rules-based order.

“The defence of our countries is closely tied to the peace and stability of the Indian Ocean, North-East Asia and the Pacific,” Captain Dalton said.

“A stable and prosperous region won’t be possible unless all countries pursue their military, economic and political objectives in a way that respects international law and a country’s sovereign rights.

“Important exercises such as MASTEX are an example of collective deterrence.

“As regional middle powers, Malaysia and Australia are making a clear demonstration to countries which may want to bring harm to us that the cost of doing so outweighs the benefits.”

Through the 2021 Comprehensive Strategic Partnership, both nations have opened new avenues for training, education and operational collaboration. 

The relationship continues to expand through cooperation in maritime security, hydrography, submarine operations, peacekeeping and exchange postings. 

Commanding Officer Warramunga Commander Ken Brown said it was at the tactical level that the strategic partnership becomes tangible.

“On the bridge, in the operations room and on the upper decks. It is in the clarity of a well-executed signal, the trust required to conduct close manoeuvres and the confidence to operate seamlessly as a combined force,” Commander Brown said.

“These are not abstract concepts. They are built through exercises like this – through repetition, professionalism and shared experience.

“Each time we have come away more capable, more cohesive and better prepared to respond to real-world contingencies.”
