Five Eyes is the long-standing intelligence partnership joining Australia, Canada, New Zealand, the United Kingdom, and the United States. Its members share sensitive collection and assessments across national systems; it is not a single supranational agency with a unified UAP database. UAP sharing within that framework refers to briefings, reporting practices, and exchanges among those partners, whose public disclosure laws and institutional responsibilities differ considerably.

A public milestone came in May 2023, when AARO director Sean Kirkpatrick told NASA’s independent study meeting that the partners had recently held their first Five Eyes forum on UAP. He described discussion of reporting, data, and the security implications of objects that might be foreign systems. AARO’s later annual reporting also described engagement with allies and partners. This establishes an official channel for consultation; it does not disclose the forum’s classified content or prove that every member maintains a dedicated investigative office.

National records reveal an uneven picture. Canada’s Sky Canada Project examined how civilian UAP reports should be collected and made public, while Canadian defense officials engaged U.S. counterparts on the issue. New Zealand has released defense records explaining where reports are referred and noting that it does not maintain a dedicated UAP investigation capability. Australian releases similarly show internal inquiries and correspondence rather than a standing public program comparable to the All-domain Anomaly Resolution Office. The United Kingdom closed its Ministry of Defence UFO desk in 2009 but continues to handle aviation and defense concerns through ordinary channels.

The importance of Five Eyes UAP sharing is practical: common definitions and compatible reporting can help distinguish drones, balloons, sensor artifacts, and foreign surveillance from observations that remain unresolved. It also places UAP inside broader international UAP programs and national-security cooperation. Public evidence supports briefings and information exchange, not claims that the alliance has jointly confirmed recovered craft or non-human intelligence. Those stronger assertions require records or attributable first-hand testimony beyond the fact that classified partners discuss unidentified objects.
