Tuvalu's first climate migrants are settling into Australian life after arriving on one of the most unique visas the Federal government has issued for foreign citizens.

The historic relocation, under a 2023 climate and security pact known as the Falepili Union, commenced this month, and is set to continue over the next decade from the tiny Pacific nation where rising seas threaten to swallow ancestral lands.

More than a third of Tuvalu's 11,000 residents applied for the sub-class visa 192.

The visa offered "mobility with dignity, by providing Tuvaluans the opportunity to live, study and work in Australia as climate impacts worsen," according to the Australian Government.

However, the intake remains capped at just 280 migrants per year.

While the small figure will have a minimal economic impact on Australia, allowing more Tuvalu residents to leave will impact the vulnerability on some of Tuvalu's most skilled workers.

Part of the deal focuses on preserving Tuvaluan culture as sea levels slowly rise around the atolls.

Among Tuvaluans moving to Australia in the initial intake is a female forklift driver, a dentist, and a trainee church pastor who is focused on preserving the spiritual life of fellow migrants.

Christian Church of Tuvalu pastor Manipua Puafolauhas relocated to Naracoote in South Australia's south-east to live with several hundred Pacific Islander migrants, which already work in the seasonal agriculture and meat processing industries.

"For the people moving to Australia, it is not only for their physical and economic wellbeing, but also for calls for spiritual guidance," Pr Puafolau said in a video released by Australia's foreign affairs department.

Dentist Masina Matolu, who has three school-aged children and a seafaring husband, decided to move to Darwin for a righteous purpose.

Dr Matolu's plans to work with Indigenous communities across parts of the Top End and return to Tuvalu to benefit her fellow citizens from the experience.

"I am really excited to go there to help out the people to serve and alleviate suffering, and I can always bring whatever I learn new from Australia back to my own home culture, just to help," Dr Matolu said in her video statement.

Forklift driver Kitai Haulapi plans to relocate to Melbourne for work opportunities.

Ms Haulapi plans to contribute to Tuvaluan society by sending money back to her family.

"I felt happy and excited when I learnt about the opportunity because it made me think about my future and the new pathway it could create for my life, living in Australia really for the betterment for my future," Ms Haulapi said.

The Australian government have established support services to assist Tuvaluan families establish themselves in Melbourne, Adelaide and throughout Queensland.

Tuvalu Prime Minister Feleti Teo recently visited a small yet thriving Tuvaluan community living in Melton on the outskirts of Melbourne to emphasise the importance of maintaining strong homeland ties as more of Tuvaluan citizens migrate.

Tuvalu, arguably the world's sovereign country at greatest risk from climate change, is a group of atolls located between Australia and Hawaii.

On Tuvalu's main atoll of Funafuti, the land is barely wider than the road.

NASA scientists have projected daily tides will submerge at least half of Funafuti — the home to more than 6000 of Tuvalu's residents — by 2050, where the majority of villagers inhabit a strip of land as narrow as 20 metres.

In a worst possible scenaroi, scientists have suggested a two-metre sea level rise would see 90 per cent of the atoll underwater within the next 25 years.
