Madam Chair, we could look at whether we have something we could bring forward to show specifically where challenges have occurred in the act in terms of defining which waterways are in or out.
I would also perhaps highlight that some of the difficulties we've heard about and we've had conversations about over the time since the amendments came into force have focused on which waters are in or out of the schedule but also on the treatment and protection required in relation to obstructions that are not in scheduled waters, because the minister's authority to deal with and quickly address obstructions applies only to the scheduled waters. So in such a case, we could ask what the instructions for protections should be outside of those scheduled waters. That again requires a decision regarding where it is critical that obstructions be dealt with. Is it only in busy waterways or could witnesses bring forward other criteria that would help inform that question as well?
