You have the option to not provide consent to a control order. However, where a person refuses to provide consent, the Commonwealth Chief Medical Officer may mandate compliance. In relation to measure regarding self-isolation or isolation at a medical facility, or a traveller movement measure, a person who does not consent must comply for the first 72 hours while the Commonwealth Chief Medical Officer considers the matter.
However, the Minister may not impose certain biosecurity obligations on an individual, such as requiring them to undergo a medical examination, requiring body samples for diagnosis, or requiring them to receive specified treatment or medication. Such measures can only be authorised under a human biosecurity control order, made by the Commonwealth Chief Medical Officer or a biosecurity officer in relation to a person who may have a listed human disease (including COVID-19).
