A new five-million-dollar seawall has been opened on the Torres Strait Island of Poruma.

It’s hoped the one-kilometre-long seawall will help the community become more resilient to erosion, high tides and severe weather.

The maintenance of the seawall will go to a regional workforce.

Poruma is one of five island communities to get a seawall.

Torres Strait Islander leaders and communities have lobbied governments and the United Nations about the threat the region faces from rising sea levels due to climate change.

Last year the Federal Court visited the Torres Strait to hear evidence on a climate change class action being brought against the Australian government by Traditional Owners.
