(1) If the Treasurer reviews an action, as allowed by section 79A, the Treasurer must:
(a) give written notice to the person who proposes to take, or took, the action of the review; and
(b) either:
(i) if the Treasurer decides that a national security risk does not exist in relation to the action--include a statement to that effect in the notice; or
(ii) if the Treasurer decides that a national security risk exists in relation to the action--include the Treasurer's reasons for deciding that the risk exists in the notice.
(2) The Treasurer may redact from the written notice to the person who proposes to take, or took, the action:
(a) any reasons that would disclose the national security risk or result in prejudice to Australia's national security interests; or
(b) any information relied on in carrying out the review of the action on grounds of national security.
(3) To avoid doubt, a written notice to the person who proposes to take, or took, the action may be validly given under subsection (1) even if all the contents of the notice are redacted.
