Australia will provide a "life-saving" package of $5 million and humanitarian supplies to help cyclone-ravaged Vanuatu.
Foreign Minister Julie Bishop says the commitment follows a request from the Vanuatu government.
"This package will include $5 million that will be provided to Australian NGOs, particularly the Red Cross and to other United Nations partners," she told reporters in Perth.
"We will also be deploying humanitarian supplies to provide support for up to 5000 people in the form of water, sanitation and shelter."
A team of medical experts and urban search and rescue personnel will also be deployed.
Dozens of people are feared dead after Super Cyclone Pam slammed into the tiny Pacific Island nation late on Friday with gusts up to 320km/h.
Australia is also sending a team of consular and humanitarian and disaster relief experts to Vanuatu, and is assisting the travel to Port Vila of a United Nations disaster assessment team.
Two military aircraft have taken off from the Amberley and Richmond bases and a surveillance plane is already in Vanuatu, carrying out reconnaissance and imagery surveillance.
Eight people are confirmed dead in and around Port Vila but that toll is expected to rise as contact is made with outlying islands.
"We have no reports of any Australian casualties," Ms Bishop told reporters.
"Over 1100 Australians are now registered in Vanuatu but we expect that there are more and so we will continue to contact hotels, accommodation throughout Vanuatu to see if there are any Australians who we have not yet made contact with."
