Senator WONG (South Australia—Leader of the Opposition in the Senate) (14:00): Mr President, welcome back to 2016. The PRESIDENT: Thank you, Senator Wong. Senator WONG: My question is to the Minister representing the Prime Minister, Senator Brandis. I refer to Mr Turnbull's statement on action to address climate change, and I quote: My view is the market-based mechanism, the emissions trading scheme, is the most cost-effective. Is Mr Turnbull's position the position of the Turnbull government?
