As soon as practicable after a security patient who is subject to a Secure Treatment Order has been received at a designated mental health service, the authorised psychiatrist must notify the Tribunal of the security patient's receipt and ensure that reasonable steps are taken to inform the following persons in relation to the security patient of the security patient's receipt—
(a) the nominated person;
(b) a guardian;
(c) a carer, if the authorised psychiatrist is satisfied that the receipt of the security patient will directly affect the carer and the care relationship;
(d) a parent, if the security patient is under the age of 16 years;
(e) the Secretary to the Department of Human Services, if the security patient is the subject of a custody to Secretary order or a guardianship to Secretary order.
