I want to return to the question of “fatigue science” for just a moment. That is being withdrawn. I think it's in subclause 17(1). But authority is being put in—I think it's in subclause 34(3)—for the authorization, if you will, for the SMS regulations to tackle the issue of fatigue management with respect to employees' scheduling.
I think Ms. Kinney referred at least notionally to some of the the restrictions in the legislative definition. I'm looking at the principles that I think are included in the gazetted SMS regulations. Can you cover the four aspects that are in the SMS regulations?
