(1) The Commonwealth domestic commercial vessel national law, as in force from time to time, applies as a law of Victoria.
(2) The Commonwealth domestic commercial vessel national law so applies as if it extended to matters in relation to which Victoria may make laws—
(a) whether or not the Commonwealth may make laws in relation to those matters; and
(b) even though the Commonwealth domestic commercial vessel national law provides that it applies only to specified matters with respect to which the Commonwealth may make laws.
(3) Subsection (2) does not operate to exclude a law of Victoria relating to marine safety that would not otherwise be excluded by the Commonwealth domestic commercial vessel national law.
(4) The regulations made under this Act may provide that the Commonwealth domestic commercial vessel national law applies under this section as if an amendment to that law—
(a) made by a law of the Commonwealth; and
(b) specified in the regulations made under this Act—
had not taken effect.
