This article interrogates the convergence of algorithmic colonialism and Indigenous futurism through a close reading of Claire G. Coleman’s Terra Nullius and The Old Lie. Situating these novels within both Australasian and global frameworks, the study illuminates how speculative fiction critiques the entrenchment of colonial logics in artificial intelligence, data extraction, and biometric governance. Drawing on theories of data sovereignty, the CARE/FAIR principles, and comparative analyses from African and Māori contexts, the article demonstrates how Coleman’s narratives unsettle Western technocratic paradigms, foregrounding Indigenous agency, refusal, and relationality. By mobilising genre innovation and narrative disruption, Coleman not only exposes the recursive violence of both historical and digital colonisation, but also proposes decolonial and abolitionist alternatives for ethical AI futures. This interdisciplinary analysis highlights the transformative potential of literary critique in advancing digital justice and reimagining the global governance of technology.
