 It formed the traditional tribal boundaries for the nomadic Bungandidj people (western bank) and Gunditjmara people (eastern bank) people from two distinct language groups.Little archeological evidence has been found of Bunganditj in-habitation along the river itself, including in the regions many caves, there is strong evidence of their presence in nearby coastal areas.While strong evidence of Gunditjmara activity has been found along the river's eastern hinterland and shell middens discovered may indicate multiple nomadic tribes camping along the river that may have used message sticks to communicate.
