Mr ABBOTT (Warringah—Leader of the Opposition) (14:23): Madam Deputy Speaker, I ask a supplementary question. My question is to the Acting Prime Minister. Given that it is just 40 days till the introduction of the world's biggest carbon tax, is the Acting Prime Minister confirming that there are 104 councils around our country, including Darwin City Council, that do not know whether they will be liable for this tax or how much? What a disgrace! The DEPUTY SPEAKER ( Ms AE Burke ): The Leader of the Opposition will withdraw. Mr ABBOTT: I withdraw. The DEPUTY SPEAKER: It is an abuse of question time to add that to the end of any question.
