This article documents Australia's use of border security support and humanitarian aid as border externalisations immobilising asylum seekers as far from Australia as possible. The Australian Government frames border securitisation through regionalism, as an effort to achieve a regional solution to asylum seeking irregular migration. Correspondingly, scholars have documented Australia's externalisations in Southeast Asia and the Pacific. However, Australia's efforts are not regionally circumscribed and this article analyses the spatial and temporal flexibility of Australia's border externalisations; Australia's strategy of targeting borderscapes of asylum seeking as they emerge and change. In doing so, the article examines how the Australian Government has assembled externalisations in South Asia, the Middle East, and North Africa. Australia's use of humanitarian aid to make places housing asylum seekers more hospitable, yet confining, to the displaced is detailed. Also analysed is Australia's border security support to source countries and countries of first asylum to immobilise asylum seekers. The article demonstrates that Australia has sought to manifest not only a territorial buffer zone in Southeast Asia, but use border externalisations in the Middle East, South Asia, and North Africa to secure places and displaced populations. This is argued to be a preventative strategy of risk management designed to preempt future asylum geographies and forge extraterritorial migration control.
