Madam Chair, if I may, I think the design of the regime for railway safety has been reviewed, as have the two particular examples of 2013 and 2015 when Railway Safety Act amendments were proposed and made.
The regime was not addressed in terms of the breakdown of how rules operate in conjunction with regulations and standards, except in a few areas of how enforcement and compliance could be improved. At this point we are operating under the legislation that exists now, and I wouldn't be able to speculate any further than that.
