ICAN Australia welcomes Tonga’s historic step toward a nuclear-free world & calls on Albanese to align with Pacific and also sign the Treaty on the Prohibition of Nuclear Weapons
MELBOURNE, AUSTRALIA – The International Campaign to Abolish Nuclear Weapons (ICAN) Australia warmly welcomes the Kingdom of Tonga’s decision to join the Treaty on the Prohibition of Nuclear Weapons (TPNW) and the Comprehensive Nuclear-Test-Ban Treaty (CTBT).
By taking this decisive step, Tonga has reaffirmed the Pacific region’s historic, unwavering leadership in global nuclear disarmament. Tonga joins the overwhelming majority of its Pacific neighbours, including Fiji, Vanuatu, Kiribati, Tuvalu, Samoa, and New Zealand, in creating a region that is ensuring nuclear weapons and testing are comprehensively rejected.
“The Pacific understands the catastrophic consequences of nuclear weapons, having borne the brunt of hundreds of nuclear explosions. By embracing the TPNW, Tonga’s actions send a clear message that real security is achieved through total prohibition and disarmament. We congratulate the government and people of Tonga for joining the TPNW, and call on the Albanese Government to now join the global majority of nations and join the TPNW without any further delay” said Janet Craven, ICAN Australia Director.
Tonga’s accession to the TPNW places Australia’s ongoing delay in signing the UN nuclear weapon ban treaty under a sharp spotlight. Despite the Albanese Government’s stated commitment to the Pacific, and Labor’s longstanding promise to join the TPNW, Australia remains a glaring gap in a region united against nuclear arms under the TPNW.
In light of Australia’s recently inked regional security treaties and defense pacts including the Vuvale Union with Fiji earlier this week, the federal government’s continued reliance on nuclear deterrence is at direct odds with the strategic priorities of Pacific allies. If Australia truly wishes to act as vuvale or family with our Pacific neighbours, it must align its security strategy with the region’s long-standing commitment to remaining nuclear free.
“In a region increasingly militarised through AUKUS and great-power competition, Tonga’s accession is a powerful assertion of Pacific sovereignty. True security in the Pacific is built on a foundation of climate justice and total denuclearisation, not the false promise of extended nuclear deterrence,” stated Reverend James Bhagwan, General Secretary of the Pacific Conference of Churches.
“While our Pacific nations unite to construct a genuine Ocean of Peace, Australia’s continued reliance on nuclear deterrence remains a profound contradiction to its claims of regional family and solidarity.”
The TPNW is the first legally binding international agreement to comprehensively prohibit nuclear weapons, with provisions requiring states to assist victims and remediate environments contaminated by nuclear testing. ICAN urges the Australian government to look beyond traditional defense pacts and support the tangible humanitarian frameworks already championed by Pacific states.
“The Pacific deserves complete freedom from nuclear weapons and their threat—not simply their management, but their total elimination. For decades, our communities and veterans have carried the severe intergenerational scars of colonial nuclear testing,” added Merewalesi Tuilau, Director of the Fiji Nuclear Veterans and Families Association.
“Australia cannot claim to stand with us in bilateral security pacts while refusing to sign the TPNW. It is time for the Albanese government to listen to the demands of Pacific states and match words with action.”
