Google's political ad library is missing paid messaging from prominent organisations trying to influence the vote over the Indigenous voice to parliament, limiting transparency around their efforts before the referendum.

Google's political ad database includes information such as how much the advertiser paid for reach, how many times an ad was shown and details such as the age, gender and location of people whom the ad is targeting. Google does not reveal this level of detail for ads not classified as political.
