Decolonisation in Oceania describes the historical transition of Pacific nations from European colonial rule to full sovereignty. Sovereignty is the power of a state to govern itself without outside interference. This process largely accelerated after World War II. During the colonial era, various European powers controlled the region. The British, French, and Dutch held significant authority over many islands. Today, Oceania consists of fourteen sovereign states. Most of these nations operate under parliamentary systems of government.

The mechanism of decolonisation varied greatly depending on the territory. Some nations achieved independence through formal legal changes. Others used peaceful political campaigns to demand self-rule. In some cases, territories moved through several administrative stages. They might start as a colony, then become a mandate or a trust territory. A trust territory is a land managed by a larger power under United Nations supervision. This oversight was meant to help the territory prepare for independence.

Different types of political relationships exist in Oceania today. Some nations are fully independent sovereign states. Others exist in a state of free association. The Cook Islands and Niue are examples of free association with New Zealand. These nations manage their own foreign affairs and defence. However, they maintain a residual constitutional link to New Zealand regarding citizenship. The United Nations recognized the Cook Islands as a state in 1992. They recognized Niue as a state in 1994.

History shows that some nations experienced a very gradual transition. Australia and New Zealand did not have a single independence day. Most British colonies in Australia gained responsible government in the 1850s. New Zealand gained similar government powers in 1856. Both became Dominions in the early 1900s. A Dominion is a self-governing nation within the British Empire. Although they acted as sovereign states by the 1920s, they delayed formal recognition. Australia finally accepted full sovereignty in 1942. New Zealand followed in 1947.

Other nations followed more distinct timelines with specific leaders. Samoa was the first small island nation in the Pacific to gain independence. It became independent from New Zealand in 1962. Nauru gained independence in 1968 after a peaceful campaign. Hammer DeRoburt served as Nauru's first head of state. Fiji transitioned from a British colony to a Dominion in 1970. Fiji later became a republic in 1987. This change followed two military coups in the country.

Some territories faced complex shifts in colonial administration. The islands of Papua New Guinea have a layered history. The Territory of Papua was a British colony. It was transferred to Australian administration in 1902. Later, the Territory of New Guinea became a UN Trust Territory. This area was under Australian administration after World War I. Papua New Guinea eventually became formally independent from Australia in 1975. Michael Somare served as the first Prime Minister.

Despite these changes, some areas remain under colonial control. The United Nations lists six non-self-governing territories in Oceania. These include French Polynesia and New Caledonia, which are French dependencies. American Samoa and Guam are territories of the United States. The Pitcairn Islands are a British dependency. Tokelau is a territory of New Zealand. This shows that decolonisation is an ongoing process in the Pacific. The map of Oceania continues to reflect these diverse political ties.
