The Australian referendum on an Indigenous Voice to Parliament is part of a long history of Aboriginal people fighting for their voice to be heard.

The referendum was called after Aboriginal and Torres Strait Islander leaders issued the Uluru Statement from the Heart, a petition calling for a First Nations Voice to be enshrined in the Australian constitution.
