Division   2 contains protections for individuals in relation to whom powers are exercised under this Chapter.

Any person who exercises a power, or imposes a biosecurity measure, under this Chapter must first consider the principles set out in Division   2. The principles aim to ensure that a power is exercised, or biosecurity measure imposed, only when circumstances are sufficiently serious to justify it, and only if it would be effective, it is appropriate and adapted for its purpose, and it is no more restrictive or intrusive than is required. Division   2 also ensures that the requirements of this Chapter do not interfere with an individual's urgent or life - threatening medical needs, and sets out the protections that this Chapter provides for a child or incapable person who is subject to a requirement under this Chapter.

Powers in this Chapter are exercised only in relation to human diseases that cause significant harm to human health. Those diseases must be listed in a legislative instrument that is made by the Director of Human Biosecurity under Division   3.
