Wills's involvement with the Aboriginal team was, on the face of it, extraordinary. In October 1861, only five years earlier, his father Horatio Wills and 18 station personnel had been killed by Aboriginal raiders at Cullin-la-ringo in central Queensland, in the largest single massacre of European colonists in Australian history. Yet Wills had grown up among the Djab Wurrung people in Victoria's Western District, spoke their language, and in May 1866 the Melbourne Cricket Club commissioned him to coach an Aboriginal team for a public match. Wills travelled inland in November 1866 to gather players from station work at Edenhope and Harrow, including Mullagh, Cuzens, Bullocky, Dick-a-Dick and Tarpot, all of whom would later tour England. Coaching took place over several weeks, with Wills speaking to the players in Djab Wurrung. The Boxing Day fixture at the MCG drew a crowd estimated at 10,000-11,000 — extraordinary for a Victorian club match. The MCC won, but the Aboriginal team performed creditably and the public reception was strong enough that a follow-up summer tour of New South Wales and Victoria was organised. Wills withdrew from the project after early 1867 amid disputes over money and over the players' welfare, and Charles Lawrence took over the coaching and captaincy. Wills's mental health, never robust after Cullin-la-ringo, declined through the 1870s; he died by suicide in 1880.
