The design tells the story of the 1939 Cummeragunja mission walk-off, a protest by the Aboriginal and Torres Strait Islander community over the conditions on the mission and their treatment from the government. Sir Doug and members of his family were among those who left Cummeragunja to settle in areas such as Shepparton, Echuca, Mooroopna, Daish’s Paddock and The Flats. The long-necked turtle is the totem of the Yorta Yorta people. The design on the shell of the top-left turtle represents the sixteen family groups of their nation. The diamonds symbolize the strength and resilience of ancestors and Elders who let the walk-off, with the white diamonds representing non-Aboriginal and Torres Strait Islander people who supported the Yorta Yorta community. The hands reflect both the youth of the community and Collingwood’s support for Aboriginal and Torres Strait Islanders. The meeting places where members of the community sat and talked before the walk-off are depicted on the right-hand side of the guernsey.
