Senator PAYNE (New South Wales—Minister for Defence) (14:21): I wish it were as simple as plugging a hole in a boat, actually. Whilst that might be a convenient metaphor for others to use, it is not one I would use. What we are examining in the Williamtown area and at the base itself are the options that are available to us in terms of management of the contaminant, in terms of the run-off of water from the base itself and of course continuing— Senator Kim Carr: What about stopping it at source? Senator PAYNE: Senator Carr, you don't understand actually, and that is a technical problem. I have indicated to the shadow minister, Senator Conroy, as I am sure he will acknowledge, that the government will—and I think probably already has—provide a briefing to those responsible on the other side, which will enable them to have a far more sophisticated understanding of the problem than the simplistic one being presented now. It is not that simple, Mr President, and we are making every endeavour to support the community. (Time expired)
