The ecological instabilities of our time, climate disruption, soil exhaustion, water scarcity, and biodiversity collapse, are not a set of discrete environmental problems. They are the visible expression of a deeper rupture: the severing, over the last three centuries, of the relationship between people and land. Grounded in an Indigenous Australian standpoint, this keynote reframes land as an organising authority, a system of relationships that sets the conditions of continuity for human life, and argues that its modern reduction to a resource lies at the root of the present crisis. It calls for an epistemic expansion: not the inclusion of Indigenous knowledge as supplement, but a rebalancing of authority around questions of whose knowledge counts and on whose terms. Drawing on the cultural interface, where Indigenous and scientific knowledge meet, it grounds this argument in living biocultural practice: in fire and cool burning, in aquaculture and the care of water and sea Country, and in the astronomical and seasonal calendars by which Country is read. It frames the renewal of these regenerative systems not as a return to the past but as resumption, undertaken under Indigenous authority. The address invites a shift from ownership to responsibility and from control to care, as a necessary widening of rigour in an age of limits.
