The Manuellas are one of the first families to arrive in Australia under a new treaty with Tuvalu, as rising sea levels threaten their homeland.
The visa was partially designed to assist those on the front-line of climate change and rising sea levels.
Professor Jane McAdam, director of the University of New South Wales' Evacuations Research Hub, explains the visa doesn't require applicants to have work or study plans already arranged.
"It provides opportunities for what we call livelihood diversification, it enables kids to go to school in Australia, for people to acquire further skills and training which they might want to use here, but equally might want to take back to Tuvalu," McAdam told SBS News.
