WELLINGTON, New Zealand (AP) — Australia on Friday offered the island nation of Tuvalu a lifeline to help residents escape the rising seas and increased storms brought by climate change.

At a meeting of Pacific leaders in the Cook Islands, Australian Prime Minister Anthony Albanese announced a plan that will initially allow up to 280 Tuvaluans to come to Australia each year. Tuvalu has a population of 11,000, and its low-lying atolls make it particularly vulnerable to global warming.

“We believe the people of Tuvalu deserve the choice to live, study and work elsewhere, as climate change impacts worsen,” Albanese said. “Australia has committed to provide a special pathway for citizens of Tuvalu to come to Australia, with access to Australian services that will enable human mobility with dignity.”

Albanese described the new agreement as groundbreaking, and said the day would be remembered as significant, marking an acknowledgment that Australia was part of the Pacific family.

He said the bilateral partnership between the two countries came at the request of Tuvalu. It is called the Falepili Union, he said, and is based on the Tuvaluan word for the traditional values of good neighborliness, care and mutual respect.

Details including the time frame were not yet available. The agreement would take effect after it moves through the countries’ respective domestic processes.

Tuvalu Prime Minister Kausea Natano said the new arrangement respected both nations’ sovereignty and committed each country to supporting the other through such challenges as climate change.

“I wish to express my heartfelt appreciation for the unwavering commitment that our friends from Australia have demonstrated,” Natano said. “This partnership stands as a beacon of hope, signifying not just a milestone but a giant leap forward in our joint mission to ensure regional stability, sustainability and prosperity.”

NASA’s Sea Level Change Team this year assessed that much of Tuvalu’s land and critical infrastructure would sit below the level of the current high tide by 2050. The team found that by the end of the century, Tuvalu would be experiencing more than 100 days of flooding each year.

“Sea level impacts beyond flooding — like saltwater intrusion — will become more frequent and continue to worsen in severity in the coming decades,” the team’s report found.

If all Tuvaluans decided to take up Australia on its offer — and if Australia kept its cap at 280 migrants per year — it would take about 40 years for Tuvalu’s entire population to relocate to Australia.

Albanese said Australia would also add more funding to Tuvalu’s Coastal Adaptation Project, which aims to expand land around the main island of Funafuti by about 6% to help try and keep Tuvaluans on their homeland.

Asked by reporters if Australia would consider similar treaties with other Pacific nations, Albanese said the Tuvalu announcement was big enough for one day, and emphasized again it came at Tuvalu’s request.

“This reflects Tuvalu’s special circumstances as a low-lying nation that’s particularly impacted, its very existence, by the threat of climate change,” Albanese said.

Albanese’s announcement came after Pacific leaders met for a retreat on the beautiful island of Aitutaki, which marked the culmination of meetings at the Pacific Islands Forum.
