The deepfake, which is marked as "AI-generated content", depicts Premier Miles dancing, to make fun of Miles for posting a video of himself making a sandwich.
Effective truth in political advertising laws already exist; they have operated in South Australia since the 1980s, were legislated in the ACT in 2020, and been proposed in other jurisdictions – including by Queensland Labor rank-and-file.
"Even when political ads are marked as AI-generated, political parties and candidates should be wary about running them. No one benefits from a race to the bottom where fake content is used to ridicule political rivals," said Bill Browne, Director of the Australia Institute's Democracy & Accountability Program.
"Queensland saw the use of one of the first political deepfakes in Australia, at the 2020 state election. It looks like the trend is continuing.
"While this deepfake was marked as AI-generated, it shows how easy it has become to create fake content - and there is no guarantee that other fake content in the Queensland election will be clearly identified. In Queensland, it is perfectly legal to lie in a political ad, and it shouldn't be.
"Elections elsewhere around the world have seen deepfake images and videos used with the deliberate intent to deceive.
"Truth in political advertising laws in Queensland, along the lines of those already in place in South Australia and the ACT, would help ensure that voters are not misled."
