I must be angry, indeed, Senator. That evidence has not been collected. The interval of one year has not been used to produce the case for this legislation. The government has not even gone away to research this issue, to the best of our observation on the Senate inquiry. If we had been assured that there was some long-term research underway by the Australian Institute of Health and Welfare, or something of that kind, we would have been reassured, but it is not there.
