Senator WANG (Western Australia—Palmer United Party Whip in the Senate) (14:31): Mr President, I ask a supplementary question. Could the minister explain how his advice could meet the legal requirements of the water trigger given that former Minister Burke wrote to the IESC on 12 March 2013 and withdrew any referral of the Watermark project to the IESC pending the amendment of the EPBC to include the water trigger in June that year?
