Relations between Australia and Indonesia became strained within months of Indonesia's attainment of independence, deteriorating as conflict developed first on the question of West Irian and then as a result of Indonesia's hostility towards Malaysia. For many years, it seemed ironical that Australia should have played a major part in the emergence of a neighbour whose external policies and internal trends endangered rather than safeguarded Australian interests. But there is more involved here than historical irony in the context of Australian-Indonesian relations. Sufficient time has now elapsed for Australian policy on the Indonesian independence question to be seen in the wider context of the whole postwar phenomenon of decolonisation. For it is not merely of interest that Australia should have assisted neighbouring Asian rebels against a European colonial Power (remembering that Australia herself was, and is, a European colonial Power) and should then have been embarrassed by the activities of the rebels coming to office. It is of greater interest that, of the immense number of colonial issues anxiously engaging the attention of international society in the 1940s and 1950s, the years which saw the virtual demise of western colonialism, this was the one issue on which Australia took up the rebel cause. Throughout this period and irrespective of the complexion of the parties in power in Canberra, Australia persistently jeopardised her regional objective of friendly relations with anti-colonial Asia by opposing strongly and, at times, bitterly the anti-colonial cause in the United Nations. If nothing else, the United Nations has provided a forum in which each year Australia and other members have been forced to declare themselves on colonial questions. And, until the 1960s when Australia switched policy, Australia fought against all the anti-colonial Powers' largely successful attempts to have developed a system of international control over colonies under the authority of Chapter XI (“Declaration Regarding Non-Self-Governing Territories”) of the United Nations charter, to tighten the trusteeship system of supervision erected under Chapters XII and XIII of the charter, and to involve the United Nations in particular disputes so as to meet alleged threats to peace — all of them being attempts, however indirectly, to hasten the attainment of independence by dependent territories. Thus, Australia supported South Africa on South-West Africa, the Netherlands on West New Guinea, the British on Southern Rhodesia and Oman, the Portuguese on their African territories, the French on Morocco, Tunisia and Algeria. But Australia opposed the Netherlands on the Indonesian question.
