Senator LUDWIG (Queensland—Minister for Agriculture, Fisheries and Forestry and Minister Assisting on Queensland Floods Recovery) (14:58): I thank the senator for his question. As I was saying, if he does have evidence of the serious allegations that he raises he should provide them to the relevant authority. I am confident that Fair Work Australia, according to its charter, will investigate all those matters, if they have substance and are brought to their attention. I will ask Minister Shorten if there are further matters that he wishes to respond to on the second supplementary question.
