The No campaign in Australia refers to the opposition to the proposed Indigenous Voice to Parliament referendum, which would give greater political rights to Indigenous people in the country. The No campaign is led by Australians for Unity, which is a merger of two previous No campaigns, Fair Australia and Recognise a Better Way. The campaign is supported by groups and individuals from across the political spectrum, including conservative lobby group Advance Australia and some populist political parties.

Arguments for the No vote include that the Voice won’t deliver meaningful change for Aboriginal and Torres Strait Islander people, or that Sovereignty and Treaty should be prioritized ahead of a Voice to Parliament. The No campaign has been accused of spreading misinformation, including claims that the referendum will divide Australia by race and that Indigenous people dont need a Voice in the country.

There are two sides to the No campaign: the conservative No campaign and the Blak Sovereign No campaign. The conservative No campaign comes from the right of politics, including prominent members of the Coalition, and has been accused of spreading misinformation. The Blak Sovereign No campaign is led by Indigenous politician Senator Lidia Thorpe and opposes the referendum on the grounds that it does not go far enough in recognizing Indigenous sovereignty.
