A biosecurity official who is making a decision to exercise a power under certain provisions of this Act must first consider the principles set out in this Part.

The principles aim to ensure that the power is exercised only if exercising the power is likely to be effective in, or to contribute to, achieving the purpose for which the power is to be exercised, is appropriate and adapted for its purpose, and is no more restrictive or intrusive than is required.

If the power is to be exercised in relation to a conveyance, the biosecurity official must consider the impact of the exercise of the power on the health and safety of any persons on board the conveyance.
