The ethics of resettlement: Australia and the Asia-Pacific Region

 

Abstract

One of the key problems at the heart of refugee protection today is that there are large numbers of refugees attempting to seek asylum and insufficient political will in many asylum-host states to receive refugees in their territories. A proportion of these attempt to come to Australia to seek refuge – either by requesting a resettlement place through the auspices of the United Nations High Commissioner for Refugees, or by arriving directly in Australian territory (by boat or plane). Asylum-seekers who arrive by boat are disadvantaged and penalised under Australian law in that they are excluded from Australian territory and processed offshore in third countries. Successive Australian governments justify these measures by emphasising that resettlement is the ‘proper’ mode for claiming asylum which ensures protection is given to those refugees who are most in need. This raises fundamental ethical questions: are those chosen by resettlement countries such as Australia necessarily the refugees who are most in need? Is resettlement as a concept ethical? And should resettlement be utilised to prevent and penalise spontaneous arrivals attempting to seek asylum in a country?

57. Migration Act 1958 (Cth), s5AA defines an ‘unauthorised maritime arrival’ as a person who enters Australia by sea at an excised offshore place, or any other place, and becomes an unlawful non-citizen as a result. Due to the controls operated in international airports in the region, those arriving by plane generally hold a valid visa and are able to claim asylum. It is those arriving by boat on unauthorised voyages (‘boat people’) who do not hold such visas and who are therefore delineated as ‘unlawful non-citizens’ under the Act.
