Sydney is a settler colonial city and deeply loved urban Country. The invasion and colonisation of Dharug Ngurra (Dharug Country) in Western Sydney – characterised by the simultaneous dispossession of people, land and law – brought new peoples, species, social borders and legal orders as well as new practices of environmental management that often sat uneasily with Country. Although colonisation and urbanisation have significantly changed Dharug Ngurra, Lore/Law and Dharug custodial responsibilities of care continue, as does the need for non-Dharug and non-Indigenous people to actively recognise and respond to their own diverse responsibilities of care with, and as, Dharug Ngurra. This paper focuses on relationships with balloon vine and lantana on the banks of Dyarubbin (Hawkesbury-Nepean River) in Yarramundi, Western Sydney. Since their arrival, balloon vine and lantana have made Yarramundi home, while forming intimate relationships with humans and nonhumans. In recent years, different Dharug practices of care have incorporated lantana and balloon vine, giving the plants a new form and new life. Through sharing experiences of the Yanama Budyari Gumada Dharug-led, Indigenous/non-Indigenous research collaboration, this paper unpacks what the balloon vine and lantana at Yarramundi teach us about not just coexisting but flourishing together in more-than-human places of ontological and legal pluralism.
