In respect of hazardous substances in the Smith review, which Mr Goldsmith inquired about, that was a review that was requested by WorkSafe as a part of their process of continuous improvement in their oversight of regulatory regimes. It made 19 recommendations, and WorkSafe is currently implementing those regulations to ensure that there is good oversight of the certifiers' regime in that particular space and we carry on our work with regulatory reform, including hazardous substances and areas like planting structures.
