Ms JULIE BISHOP (Curtin—Deputy Leader of the Opposition) (14:09): My question is to the Minister for Foreign Affairs. Will the Minister for Foreign Affairs advise the House of one single country—just one will do—with an economy-wide carbon tax greater than the Australian carbon tax, set at $23 per tonne and going up to $131 per tonne? Opposition members interjecting— The SPEAKER: Order! The honourable the Minister for Foreign Affairs will commence his answer once the House is silent. The minister has the call.
