The Minister may privately declare a critical infrastructure asset to be a system of national significance.
The Minister must notify each reporting entity for an asset that is a declared system of national significance.
If a reporting entity for an asset that is a declared system of national significance ceases to be such a reporting entity, or becomes aware of another reporting entity for the asset, the entity must notify the Secretary.
Note: It is an offence to disclose that an asset has been declared a system of national significance (see section 45).
