The interaction between the Wurundjeri people and the early settlement of Melbourne was told in the 2004 book – A bend in the Yarra : a history of the Merri Creek Protectorate Station and Merri Creek Aboriginal School 1841–1851, which Clark co-authored with Toby Heydon.
Clark has also written on the Aboriginal presence on the Ballarat goldfields in the 1850s noting that while there is no evidence for any direct involvement of Aboriginal people in the events of the Eureka Rebellion in 1854, aboriginal people may be relevant to the Eureka story through the event taking place on Wathaurong aboriginal land. The early policing of the Goldfield was done by the Native Police Corps, and oral history that Aboriginal people looked after some of the children of the Eureka miners after the military storming of the Eureka Stockade and subsequent massacre of miners.[4]
