Accelerating climate change and widening inequalities demand new conceptual tools for understanding how social work can contribute to reparative climate justice. Written from the Australian context where social work remains systematically undervalued, particularly within the disaster sector, this article brings feminist care ethics into dialogue with critical economic and climate justice scholarship to articulate a renewed conceptual framework for the profession. Drawing on Tronto’s ethics of care, Holten’s critique of the devaluation of caring labour, and Raworth’s Doughnut Economics, this article examines the institutional logics that externalize the costs of care and obscure interdependence, thereby reproducing structural inequities. By integrating these bodies of work, I propose a relational rights-based model that positions care as both diagnostic and transformative: a lens to understand the systemic drivers of injustice, and as a guide for shaping reparative climate responses. This model foregrounds responsibility, relationality, reparations, and planetary limits as core to social work’s ethical and political project. I argue that social work in Australia is uniquely placed to influence disaster governance, climate justice policy, and supported community outcomes, and that this influence can be increased if its knowledge, labour, and ethical commitments are recognized as central, rather than peripheral, to just climate futures.
