Overview

  • Foreign Minister Penny Wong and Defence Minister Richard Marles signed the agreement in Sydney alongside UK counterparts David Lammy and John Healey during annual ministerial talks.
  • The pact commits both nations to joint development of next-generation nuclear-powered submarines, including workforce training and infrastructure build-out in Australia.
  • Officials estimate the treaty will unlock over $40 billion in UK exports across 25 years and sustain tens of thousands of high-skilled jobs in both countries.
  • The agreement is strictly bilateral, leaving US involvement under a Pentagon review of AUKUS strategic and industrial commitments.
  • The signing coincided with Talisman Sabre exercises in Darwin, where the Royal Navy’s HMS Prince of Wales joined tens of thousands of allied personnel.
