Our paper explores the complex place-based relations of cross-sector partnerships between Indigenous and non-Indigenous partners. We draw on a longitudinal in-depth case study of the Bundian Way, an Indigenous-led cross-sector partnership of over 40 organisations. Through practices of listening to history and walking ‘on Country’, the non-Indigenous partners and our team came to appreciate the indivisibility of place and time and bear witness to the intergenerational trauma of colonially imposed divisions. By combining a 45-day place-based ethnography with a 36-month participant (...) observation and repeated interviews with the Advisory Committee members, we explain how non-Indigenous members of the cross-sector partnership came to realise, and reverse, these place-time divisions. We contribute to an ethics of custodianship by first contrasting, and then combining, Indigenous and Western ways of knowing place through time. (shrink)
