Until as recently as 1992 with the landmark Mabo v. Queensland (No. 2) decision, Australia had operated under the terra nullius doctrine, or the idea that Australia was “uninhabited” prior to European settlement. As a result, white settlers engaged in brutal conquest, stealing indigenous land and slaughtering many of the First Peoples. However, even before the rejection of terra nullius, starting in 1979, the High Court of Australia began frequently ruling in ways that align with the interests of the First Peoples. In this project, I seek to examine the trends of the High Court’s indigenous land rights rulings from 1979-2008. In light of Australia’s history of genocidal oppression of the First Peoples, why have the majority of the High Court’s rulings in the area of indigenous land rights supported the interests of the First Peoples? I use qualitative analysis to code cases in terms of whether the decisions advance or oppose the interests of the First Peoples, and how far-reaching the results are. Additionally, I synthesize scholarship regarding the domestic indigenous rights movement, Australian political climate (defined by government policy), and international pressure to examine how these components may have interacted to yield the majority of these land rights decisions, which are, perhaps surprisingly, “pro-First Peoples”. Overall, I find that throughout the time period of study, each of these three key components waxes and wanes in significance, constantly interacting by both provoking and responding to change. Considering the continuing marginalized status of the First Peoples today, these findings offer hope that the High Court can be a powerful avenue for the expansion and protection of indigenous land, one that is responsive to multiple different levels of political organization, from grassroots movements all the way to the United Nations.
