Senator WONG (South Australia—Leader of the Opposition in the Senate) (14:53): Mr President, I ask a further supplementary question. I refer the minister to Ms Tracey Ann Cain's role as the owner of a lobbying firm that represents Cadbury, Kraft and the Australian Beverages Council, all of which have a commercial interest in food-labelling policy and which have expressed opposition to healthy star ratings. Can she outline to the Senate her chief of staff's relationship with the lobbying firm and Ms Cain? When did her chief of staff declare this relationship to the minister, her department and the Prime Minister's office?
