Prominent Aboriginal leaders, William Cooper, William Ferguson and John Patten decided to bring Aboriginal people together in a Day of Mourning and Protest
They had previously petitioned about recognising Aboriginal rights to the governments of Australia and Great Britain who refused to pass them on to King George V
Prime Minister Joe Lyons did agree to meet with the Day of Mourning leaders the day before the protest (some media reports attributed this more to Lyons' desire to meet Pastor Doug Nicholls, an AFL player for Fitzroy at the time, than to any desire to constructively negotiate)
