William Cooper (c.1860 – 1941) was an Australian Aboriginal political activist and community leader.
William Cooper was born in Yorta Yorta territory around the intersection of the Murray and Goulburn Rivers in Victoria, Australia on 18 December 1860. Cooper appears to have been forced to work for a variety of pastoral employers, even as a child.
On 4 August 1874, William Cooper, along with his mother, Kitty, his brother Bobby and other relatives arrived at Maloga, an Aboriginal Mission on the Murray, run by Daniel and Janet Matthews. Three days later, Matthews was struck by William’s quick progress in literacy, and noted the following in his diary:
"6 Aug. Maloga. The boy, Billy Cooper, shows great aptitude for learning. He has acquired a knowledge of the Alphabet, capital and small letters, in three days and then taught Bobby – capitals only – in one day."
Cooper came and went from the mission freely, learning and working as it suited. In his 20s, he seems to have taken a great interest in the message of the Bible. Following a church service in January, 1884, Cooper approached Daniel Matthews and said "I must give my heart to God…." He was the last of his brothers and sisters to become a Christian.
The faith community seems to have nourished Cooper for a life of activism. "Matthews' evangelical work provided Cooper and other Yorta Yorta with powerful way of understanding and protesting against their plight, and so helped equip them to fight for equality."
From 1881, Cooper was educated by Thomas Shadrach James, a highly educated Tamil from Mauritius, who had moved to Maloga to become the resident teacher. Cooper read widely, learning of the indigenous rights movements in North America and New Zealand.
Cooper's long campaign for Aboriginal rights, especially land rights, began with the Maloga Petition in 1887. One of eleven signatories, it was addressed to the Governor of New South Wales. The petition held that Aborigines of the district, "should be granted sections of land not less than 100 acres per family in fee simple or else at a small nominal rental annually with the option of purchase at such prices as shall be deemed reasonable for them under the circumstances, always bearing in mind that the Aborigines were the former occupiers of the land. Such a provision would enable them to earn their own livelihood..."
