ABC managing director Hugh Marks told Senate estimates on Tuesday that he became aware of One Nation's potential breach of intellectual property last week and sought legal advice. "We will be taking further action, I can assure you," he said.
The ABC has described the cartoon as "shocking and disrespectful". It says the depiction of Bluey, a globally beloved Australian children's character, repeatedly ramming politicians breaches the broadcaster's intellectual property rights.
The planned cease and desist letter signals the ABC intends to enforce its rights over the use of Bluey in political material, with Marks indicating further steps are to come.
