More than a third of the population of Tuvalu has applied to move to Australia, under a landmark visa scheme designed to help people escape rising sea levels.

The island nation – roughly halfway between Hawaii and Australia – is home to about 10,000 people, according to the latest government statistics, living across a clutch of tiny islets and atolls in the South Pacific.

With no part of its territory above six meters, it is one of the most at-risk places in the world to rising seas caused by climate change.

On June 16, Australia opened a roughly one-month application window for what it says is a one-of-a-kind visa offering necessitated by climate change. Under the new scheme, Australia will accept 280 visa winners from a random ballot between July and January 2026. The Tuvaluans will get permanent residency on arrival in Australia, with the right to work and access public healthcare and education.

More than 4,000 people have applied under the scheme, according to official figures seen by CNN.
