Abstract: This paper uses autoethnography and a narrative approach to examine trust-building that occurred between Indigenous people (Larrakia and Kunwinjku) in the Top End of Australia and the author. Trust was first established when an elder adopted the author to protect her from prosecution after she caught a snake. That trust was extended to visiting birdwatchers that Larrakia and their Kunwinjku relatives met at the author's home. Consequently Kunwinjku elders asked the author, a birdwatching guide, to help them establish a tourism project on their country. This paper investigates our use of tourism as a vehicle for further trust-building that resulted in the exchange of knowledge beneficial to both Bininj and the wider society, and aided Bininj growth of self-confidence. However it also exposes the limitations of the tourism industry and government institutions in building trusting relationships and explores the possibility of a business model built on the sharing economy.
