Canberra, Australia — Marking a powerful milestone in two centuries of friendship, His Majesty King Tupou VI and Queen Nanasipau’u of Tonga have arrived in Australia for a historic state visit from 18 to 24 September, celebrating 200 years of diplomatic and cultural ties between the two nations.

The visit underscores a shared commitment to shaping a peaceful, stable, and prosperous Pacific region.
Today, in a landmark moment, His Majesty joined Australia’s Governor-General, Her Excellency Sam Mostyn AC, Tongan Deputy Prime Minister Dr Taniela Fusimālohi, and Australia’s Attorney-General the Hon Michelle Rowland MP to witness the signing of a Statement of Intent—a pledge to elevate bilateral relations through a comprehensive agreement named Kaume’a Ofi, meaning “close friends.”
The Kaume’a Ofi agreement reflects the warmth, trust, and shared values that have defined the Tonga–Australia relationship for two centuries.
It promises deeper cooperation across diplomacy, development, and regional security.
In addition, both countries will sign a Memorandum of Understanding on Cyber Cooperation, aimed at strengthening national security, managing cyber threats, and harnessing emerging technologies for mutual benefit.
Their Majesties’ visit also highlights the rich cultural and personal connections between the two nations.
A special church service in Sydney, led by Reverend Charissa Suli—the first Tongan Australian to become President of the Uniting Church in Australia—will bring together members of the Tongan diaspora from across the country.
In recognition of Tongan Australians who contributed to disaster relief efforts following the 2022 Hunga-Tonga-Hunga Ha’apai volcanic eruption, His Majesty will confer Royal Order of the Crown of Tonga and Coronation Medals.
Her Majesty Queen Nanasipau’u will lend her support to Australian researchers working to combat cervical cancer, reinforcing the shared commitment to health innovation and scientific collaboration.
This royal visit not only celebrates a historic milestone but also sets the stage for a future of deeper partnership and mutual respect between Tonga and Australia.
