Australia has entered into a ground-breaking pact with Tuvalu, offering refuge to its citizens due to the severe impacts of climate change, particularly rising sea levels threatening the low-lying Pacific atolls of Tuvalu. The agreement, termed the Falepili Union, marks the first instance of Australia providing residency to foreign nationals in response to climate change threats. Up to 280 Tuvalu citizens annually will be granted visas permitting them to live, work, and study in Australia. Australian Prime Minister Anthony Albanese emphasized the nation's acknowledgment of its responsibility within the Pacific family, committing to both climate action and security assistance for Tuvalu. The treaty also includes Australia's defense commitment to Tuvalu against military aggression and Tuvalu's agreement not to enter defense pacts with other nations without Australia's approval. Additionally, Australia has pledged financial support, including A$16.9 million, to help Tuvalu adapt to climate change, with initiatives such as expanding the landmass of its main island by 6%. The pact is deemed the most significant agreement ever between Australia and a Pacific country.
