The Regulations Review Committee examined all three of the orders that I've just mentioned and didn't raise any concerns about them. They did express concerns about the fourth, and that is the COVID-19 Public Health Response (Self-isolation Requirements and Permitted Work) Amendment Order 2022. That's the order that authorised the Director-General of Health to exempt COVID-19 cases from self-isolation requirements whilst undertaking specific work or travelling to undertake specific work, and it authorised the imposition of any conditions on that exemption. This was basically the ability for people in a limited number of circumstances who may have COVID-19 to go back to work where the risk of them not being at work was greater than the risk posed by them going to work when they had COVID-19. It's a very limited provision, and actually I don't think it has been used—certainly it hasn't been used extensively—if, in fact, it has been used at all.
