This section applies if:
a direction is in force under section 35AQ in relation to a Ministerial authorisation; and
the direction was given to a particular entity.
The Secretary may, by written notice given to the entity, revoke the direction.
If the Secretary is satisfied that the direction is no longer required to respond to the incident to which the Ministerial authorisation relates, the Secretary must, by written notice given to the entity, revoke the direction.
If the Ministerial authorisation ceases to be in force, the direction is revoked.
This section does not, by implication, affect the application of subsection 33(3) of the Acts Interpretation Act 1901 to an instrument made under a provision of this Act (other than this Part).
