Senator WATERS (Queensland) (14:25): Mr President, I ask a supplementary question. If the proposed dumping fee had been imposed on the 22 million cubic metres of dredge spoil already approved to be dumped in the reef World Heritage area, it would have raised more than GBRMPA's current annual budget. Can the minister advise how this dirty money for dirty deeds is anything other than an incentive for GBRMPA to approve more dumping? Opposition senators interjecting— Senator Bob Brown: On a point of order, Mr President: the senator from South Australia to my right is making very clear allegations about a matter before the Privileges Committee. I ask you to have him withdraw. Senator Ian Macdonald: On the point of order, Mr President: you did not hear that and I assure the Senate and everybody else that Senator Bernardi did not say what Senator Brown alleges—and this is another occasion where Senator Brown simply verbals anyone he does not agree with. Honourable senators interjecting— The PRESIDENT: Order! I did not hear anything at all, Senator Brown; I can assure you of that. If there was a comment, it was certainly not heard up here. I am attempting to get silence so Senator Waters can have her question heard properly. Senator Waters, please repeat the last part of your question—which I did not hear because of the disorderly exchanges across the chamber. Senator WATERS: Can the minister advise how this dirty money for dirty deeds is anything other than an incentive for GBRMPA to approve more dumping? Are there any safeguards proposed to ensure that this does not just incentivise the regulator to approve more dumping?
