NAIDOC is a celebration of Aboriginal and Torres Strait Islander cultures and an opportunity to recognise the contributions of Indigenous Australians in various fields. Its origins can be traced to the emergence of Aboriginal groups in the 1920s which sought to increase awareness in the wider community of the status and treatment of Indigenous Australians. NAIDOC stands for National Aborigines and Islanders Day Observance Committee. Activities take place across the nation during NAIDOC Week in the first full week of July. All Australians are encouraged to participate.
