The Australian government says the welfare of Pacific workers and students still in Australia is a priority for it.
Changes in visa arrangements will allow Pacific workers who are unable to return home to stay and work in for up to another 12 months.
Students who have completed their studies, but are unable to return home, are also able to extend their visas.
Australia is also working to maintain an essential services and humanitarian corridor to enable the movement of essential personnel and supplies, including medical equipment and food.
Meanwhile, Canberra has given Nauru $US2.9 million dollars to help it cope with Covid-19
