In this chapter we offer a narrative of ‘care-full collectives’ in education. The narrative is assembled by weaving together the ‘data stories’ of a doctoral inquiry with the re-collections of the authors over time. These data stories are interpretations of encounters had by three teenaged boys caring-with their more-than-human, creek-side community in Narrm Melbourne. The young people were students in a public high school when they participated in the doctoral inquiry conducted by the first author (Alicia), whose project was supervised by the other two authors (John and Jeana). Collectivised care through the boundary-hopping ethics of riparian relations, is offered as an educative-relational response to this place-time of entangled crises in this ancient land with ongoing Indigenous practices of caring for Country. The praxis of ‘sympoethical withnessing’ is proposed; ethics based on the critical posthuman ontology of ‘sympoiesis’ through the care-full—tact-full, thought-full, response-full—expressions of more-than-human relations.
