I think that's one of the main purposes of the Act, to protect the environment and the health and safety of people and communities from the adverse effects of hazardous substances, but the problem we've got at the moment is that reassessments and assessments of hazardous substances can take a long time, take quite an in-depth process, and so what happens is it may mean the delayed entry of new chemicals coming in which could actually replace more unsafe chemicals. That happens. Then, basically, the other issue is that some chemicals may continue to be used, or the controls continue to be used, when they really shouldn't, and so it's really important that we do get more efficient in terms of the assessment process.
