Foundations & principles

The FPDA’s founding principles continue to form the bedrock of activities and exercises. First, as a defensive arrangement, the FPDA should maintain a non-threatening posture to avoid rousing sensitivities in the region. Second, as a multilateral security arrangement, the FPDA should proceed at a pace comfortable to all, cognisant of multilateral, bilateral and national sensitivities. Third, given the constantly changing strategic environment, the FPDA should continually develop and evolve to remain relevant as a security arrangement. At the 10th FPDA Defence Ministers’ Meeting in 2017, the founding principles were contemporised to the ‘3Rs’. The 3Rs complement the founding principles and together they continue to guide the FPDA decision making and activity. First, the FPDA should not deviate from its Remit in contributing to the external defence of

History

The FPDA was set up following the termination of the United Kingdom's defence guarantees of Malaya under the Anglo-Malayan Defence Agreement, as a result of the UK's decision in 1967 to withdraw its

) agreed to consult one another in the event of armed aggression against Malaysia and Singapore. The 1971 Joint Communiqué states: “In the event of any form of armed attack externally organised or supported or the threat of such attack against Malaysia and Singapore, their governments would immediately consult together for the purpose of deciding what measures should be taken jointly or separately in relation to such attack or threat”. In line with the FPDA Joint Communiqué of 16 April 1971, two councils, the Joint Consultative Council and the Air Defence Council, were established. The Joint Consultative Council provided a forum for regular consultations at the senior official-level on matters relating to the defence arrangements. The Air Defence Council was responsible for the functioning of the Headquarters Integrated Air Defence System (HQIADS). With the expansion and complexity of FPDA exercises and the move towards joint and combined exercises over the years, the two councils were amalgamated in terms of their functions and tasks as well as memberships to improve the management and coordination of FPDA activities. The merged Council was named the FPDA Consultative Council (FCC).


Air defence

During the early years of FPDA, the arrangements were focused on the air defence of Malaysia and Singapore. Commander IADS held the responsibility and authority for operational air defence. By 1990, Malaysia and Singapore’s military capacity progressed, and the FPDA’s focus shifted towards training and support. The FPDA based at RMAF Butterworth under the command of an Australian

Area defence system

In 1981, the five powers organised the first annual land and naval exercises. Since 1997, the naval and air exercises have been combined. In the 1990s, land exercises were added to the exercise programme and by 2000 the FPDA was actively pursuing the development of a capability for joint and combined operations in which air defence would contribute only as part of broader air, land, and maritime operations. In 2001, HQ IADS was redesignated Headquarters Integrated "Area" Defence System. It now has personnel from all three branches of the armed services, and co-ordinates the annual five-power naval and air exercises, while moving towards the fuller integration of land elements. An annual FPDA Defence Chiefs' Conference (FDCC) is hosted by either Malaysia or Singapore, and is the highest military professional forum of the FPDA and serves as an important platform for dialogue and exchange of views among the Defence Chiefs. There is also a Five Powers Defence Arrangements Ministerial Meeting (FDMM). John Moore, then Minister of Defence of Australia said, "As an established multilateral security framework, the FPDA has a unique role in Asia. It is of strategic benefit to all member nations and, in Australia's view, to the wider Asia-Pacific region." Malaysia's CDF, former General (GEN) Tan Sri Dato' Sri Zulkifeli Bin Mohd Zin concurred: "We can help each other... and cooperate with one another." In the latest New Zealand defence White Paper released in June 2016, it was outlined that given New Zealand was a longstanding member of the Five Power Defence Arrangements, it would, "meet its commitments should Malaysia or Singapore be subject to a military attack."

On 18 October 2021, FPDA celebrated its 50th anniversary with joint air and naval displays involving the ships and aircraft of the member countries. These were observed by Singaporean Defence Minister Ng Eng Hen and the High Commissioners of Australia, Malaysia, New Zealand and the United Kingdom.

50 years and beyond

The five member-nations continue to contribute to combined and joint exercises, and training opportunities that focus on high-end conventional warfighting, while also being flexible in responding to the changing security landscape. This includes expanding maritime security, counter-terrorism, HADR, and non-combatant evacuation operations. Additionally, new and emerging capabilities will become more prevalent over the next decade, such as cybersecurity and unmanned aircraft systems. Progress on developing capacity in these areas will continue to be made at a pace comfortable to all member-nations.
