In 1999, Australian Foreign Minister Alexander Downer welcomed Tonga's admission to the United Nations. The Minister said that the Australian Government had helped fund the Commonwealth Small Island States Office in New York so Pacific states can afford to be represented here.
Following the outbreak of violence in Tonga in 2006, the Tongan Government asked the Australian Government for assistance from Australian forces. Following this request, eighty-five Australian soldiers and police were sent to Tonga with support from New Zealand.
Australia is the largest donor of aid to Tonga through its Ausaid program. In 2008/09, Australian aid amounted to AUD13.2M Australian Foreign Minister Stephen Smith said in 2009 that Tonga was an important partner of Australia in the Pacific. He further added "We have extensive development assistance programs with both countries [Samoa and Tonga] and we have very strong people-to-people links.
