Most of Tuvalu applied for a new Australian visa; why?

Last month, around 80% of Tuvalu's population balloted for a new Australian visa. The 'Falepili Mobility Pathway' is a response to the erosion of Tuvalu's territory caused by rising sea levels; each year, 280 Tuvaluans will be chosen to apply for the visa, which allows unrestricted movement and the right to work in Australia.
