Over a third of Tuvalu's population is applying for a climate visa to Australia due to rising sea levels threatening their islands. The Falepili Union treaty allows Tuvaluans to live, work, and study in Australia, but the number of applicants far exceeds the available visas. Experts highlight the economic and climate pressures driving this migration, while also noting the cultural ties Tuvaluans have to their homeland. The treaty aims to provide a pathway for Tuvaluans while emphasizing the need for international climate action.
