Mate it's not even illegal according to the AEC to mimic AEC livery and 'how to vote' forms and placards to trick Chinese immigrants into voting for the LNP.

Nor is it illegal to hand out "How to vote for Greens / LNP / Labour" cards at polling stations as a member of an opposition party, and deceptively place all preferences for the opposite intentions.

Nor is it illegal to mimic the AEC and puport to simply be a government representative enabling your application to a postal vote, while actually being from Liberal or Labor party and taking any submitted information as your own, to do whatever you like with.

So there's zero chance they'll care about a party misrepresenting their political goals.

Australians have very little freedom of speech enshrined in law, but what little there is aims to protect politicians only.
