(1) At any time, by notice in writing to the licensee, the Secretary may vary a licence by:
(a) amending or revoking a licence condition; or
(b) imposing an additional licence condition.
(2) However, the Secretary must not vary a licence unless:
(a) the licensee has contravened the Act, these Regulations or a licence condition; or
(b) there is reason to believe that the variation is necessary, having regard to a matter mentioned in regulation 4AM.
(3) Before making a decision to vary a licence, the Secretary must give to the licensee:
(a) notice in writing of the proposed variation and the reason for the variation; and
(b) a reasonable opportunity to make representations about the proposed variation.
Note: An application may be made to the Administrative Review Tribunal for a review of a decision by the Secretary under this regulation--see regulation 4CN.
