Five Power Defence Arrangements

The Five Power Defence Arrangements (FPDA) are a series of bilateral defence relationships established by a series of multi-lateral agreements between Commonwealth countries Australia, Malaysia, New Zealand, Singapore, and the United Kingdom.

Signed in 1971, the FPDA consists of the five powers consulting each other "immediately" in the event of threat or an armed attack on any of the FPDA members for the purpose of deciding what measures should be taken, jointly or separately in response.

There is no specific commitment to intervene militarily, and the agreement is merely consultative. The Five Powers Defence Arrangements do not refer to exclusive economic zones (EEZ), and the enforcement of a state's EEZ rights is a matter for that state, which may request the assistance of other states in so doing.

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 Malaysia and Singapore. Second, the FPDA should develop and evolve to ensure its Relevance as a regional security arrangement at a pace comfortable to all. Third, the FPDA should maintain its purpose and portrayal as a defensive arrangement to provide Reassurance to the region.

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 armed forces east of Suez on 1 November 1971. Under the Five Powers Defence Arrangements, the five member-nations of (Australia, Malaysia, New Zealand, Singapore and the United Kingdom) 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.
