Australia's foreign minister urged Pacific island countries on Thursday to stay united in the face of great power competition as she visited New Caledonia, where the president raised concerns about Australia's AUKUS nuclear submarine programme.

Foreign Minister Penny Wong's visit to the French territory coincides with a push by a China-backed group for several Pacific island nations, including New Caledonia, to sign a splinter security pact.

The region's main diplomatic bloc, the 18-member Pacific Islands Forum, which includes Australia, last year rejected a push by China for 10 nations to sign a security and trade deal amid concerns by the United States and its allies over Beijing's military ambitions.

Solomon Islands, the only Pacific island country with a security pact with China, is pushing for the Melanesian Spearhead Group of Vanuatu, Fiji, Papua New Guinea, Solomon Islands and New Caledonia's leading pro-independence party, to create a sub-regional security framework which would also involve Beijing, statements show.

In a speech to New Caledonia's Congress, Wong said the Pacific faced challenges from climate change, economic recovery after the COVID-19 pandemic and strategic competition, and "we believe a united Pacific Islands Forum is central to protecting our shared interests".

"We are stronger together," she said.

While New Caledonia is a French overseas territory, its president Louis Mapou, a pro-independence indigenous leader, is from the Kanak Socialist Liberation Front (FLNKS), a political alliance strongly tied to the Melanesian Spearhead Group, which was formed four decades ago to push for independence for indigenous Melanesian groups.

A spokesman for Mapou told Reuters that New Caledonia is negotiating to become an associate member of the MSG, and confirmed the security framework was being discussed among members.

"In terms of China's presence, the president has always said New Caledonia is open to discussions with any countries - China, Japan, United States," he said.

Mapou's spokesman said he had raised New Caledonia's concerns about whether AUKUS, a defence technology partnership with the United States and Britain to sell Australia nuclear-propelled submarines, complied with the Pacific's nuclear-free treaty in discussions with Wong. Wong responded saying Australia was transparent and the AUKUS submarines would carry only conventional weapons, he said.

Wong told reporters afterwards AUKUS would contribute to regional stability, and Australia complied with the nuclear non-proliferation treaty.

Solomon Islands and Papua New Guinea officials will discuss a MSG security framework on Thursday in Honiara, a Solomon Islands government statement said.

The top official for the group, whose headquarters in Vanuatu was funded by Beijing, has previously said Chinese security assistance would also be considered and China would become a development partner.

Britain's Foreign Secretary James Cleverly, who arrived in Solomon Islands on Wednesday after visiting Papua New Guinea, wrote in a tweet: "The security of the Pacific region affects us all".
