I doubt they would need to enact truth in political advertising laws for that. Dutton and his colleagues have shown a willingness to flex defamation laws when people say things that make them feel sad. They are also privileged enough to be among the few who have the financial means to pursue those kinds of actions.

My guess is you’d end up with a bunch of strategically expensive defamation actions that are intended to tie up those sort of advertisements until after the election.

Now, if it was something that would stop the Greens or teals from building more support? Watch that fly through Parliament with bipartisan approval.
