Before the Second World War, the relationship between Australia, the Netherlands and the Netherlands East Indies (NEI) was marked by cordial distance rather than active diplomacy. There were no resident embassies , no treaties of alliance, and few direct communications between the two governments. Australia’s foreign affairs were largely managed through Britain, and the Dutch Empire’s attention remained fixed on Europe and internal colonial administration. The war changed all of that.

The Japanese threat to Southeast Asia and the fall of Singapore in 1942 revealed the weaknesses of Australia’s reliance on British strategic leadership. Prime Minister John Curtin’s landmark declaration that Australia now looked to the United States rather than Britain marked the start of a new foreign policy era. In this new context, Australia began to engage directly with its regional neighbours—including the exiled NEI authorities.

For the Dutch, the collapse of the NEI in early 1942 meant their administrative and military presence had to be re-established elsewhere. Lieutenant Governor-General Hubertus van Mook fled Java in early March with a small group of senior officials and, on arrival in Australia, immediately created a provisional NEI administration to preserve Dutch authority in exile. For security reasons, this was not made public at first. About two weeks later, the Australian government officially recognised the Dutch administration, and Prime Minister John Curtin offered a warm welcome, promising political and material support.

Initially based in Sydney, the administration soon relocated to Melbourne, where Dutch naval and merchant operations were concentrated and where coordination with Australian and American military authorities was easier. Cabinet discussions in Canberra formalised the arrangement: Australia treated the NEI administration as a sovereign Allied government-in-exile. This gave the Dutch legal authority over their forces, shipping, and civilians on Australian soil, even as their military assets were increasingly integrated into Allied operations under the South West Pacific Area command.

As a result, Dutch–Australian contact became daily and operational—transforming a previously distant relationship into a functional partnership.

However, this transformation was not smooth. As Jack Ford notes in Allies in a Bind, there was no existing diplomatic structure between the two governments. Everything had to be improvised. Requests for cooperation were often routed through British intermediaries. When Australia began asserting its own foreign policy, Dutch officials were not always sure whether they were speaking to a fully empowered government or a subordinate dominion. On the Australian side, there was uncertainty about who spoke for the Netherlands: Batavia or London.

R. W. A. van den Berg in Unchained Interests shows how the Allied war effort gradually forced more streamlined coordination. The creation of ABDACOM in 1942, despite its short lifespan, required formal Dutch–Australian collaboration. Following the collapse of ABDACOM and the occupation of the NEI, Dutch diplomatic, naval, purchasing and civilian organisations in Australia assumed increasingly important responsibilities. Their activities required sustained coordination with Australian authorities and, subsequently, the Allied South West Pacific Area command.

Despite these developments, both Dutch and Australian officials found themselves sidelined within the newly formed South West Pacific Area (SWPA) command. Led by U.S. General Douglas MacArthur, SWPA prioritised American strategic goals, often leaving other Allied partners with little influence in decision-making. Dutch military units and assets were incorporated into SWPA operations, but Dutch commanders had minimal input at the strategic level. Australian officials similarly resented the lack of consultation, especially as their territory and forces were central to the Pacific campaign. This unequal power dynamic created diplomatic tension and reinforced the need for more independent foreign policy structures in both nations.

MacArthur’s leadership further complicated relations within the Allied command structure. His operational priorities were determined principally by the wider American-led Pacific strategy, leaving Dutch representatives with limited influence over decisions concerning the eventual liberation of the Netherlands East Indies. Australian political and military leaders also experienced disagreements with MacArthur over strategic priorities and consultation. These tensions illustrated the difficulties faced by smaller Allied partners in influencing a command structure dominated by the United States.

An important development was the establishment of the Netherlands East Indies Commission for Australia and New Zealand in April 1942. Based initially in Melbourne, the Commission coordinated commercial, administrative and other Netherlands East Indies interests in Australia, working alongside the Netherlands diplomatic representatives and military organisations. Its responsibilities evolved as the war continued. In 1944, a more formal Netherlands East Indies Government-in-Exile was established under Lieutenant Governor-General Hubertus van Mook, with its headquarters subsequently located at Camp Columbia in Brisbane. This development reflected the growing importance of Australia as the principal base for the displaced NEI administration.

Australia’s wartime experiences accelerated the development of a more independent foreign policy. Although the Commonwealth already had a Department of External Affairs and had begun establishing overseas diplomatic representation before the Pacific War, the conflict greatly expanded Australia’s direct involvement in international diplomacy and regional security. Canberra increasingly developed its own positions on questions affecting the Asia-Pacific region, including the future of Indonesia.

For the Dutch, the collapse of the Netherlands East Indies in March 1942 required the urgent reconstruction of administrative and military arrangements outside the occupied territory. Lieutenant Governor-General Hubertus van Mook escaped from Java and arrived in Australia with senior officials who began organising the continuation of Netherlands East Indies affairs in exile. Australian authorities welcomed their presence and provided political and practical assistance, although the precise division of responsibilities between the Dutch representatives in Australia and the Netherlands Government-in-Exile in London remained a sensitive issue.

Dutch civilian, naval, military and purchasing organisations developed activities in several Australian cities, including Sydney, Melbourne and Brisbane. These arrangements enabled Dutch personnel, shipping and military assets to contribute to the Allied war effort. However, the Netherlands East Indies was not an independent sovereign state, and its representatives in Australia did not constitute a separate sovereign government. Their authority ultimately derived from the Kingdom of the Netherlands, whose government was based in London.
