(1) An explanatory section is:
(a) any section that is the first section in a Division and that has as its heading "What this Division is about"; or
(b) any section in Divisions 2, 3 and 4.
(2) Explanatory sections form part of this Act, but they are not operative provisions. In interpreting an operative provision, an explanatory section may only be considered:
(a) in determining the purpose or object underlying the provision; or
(b) to confirm that the provision's meaning is the ordinary meaning conveyed by its text, taking into account its context in this Act and the purpose or object underlying the provision; or
(c) in determining the provision's meaning if the provision is ambiguous or obscure; or
(d) in determining the provision's meaning if the ordinary meaning conveyed by its text, taking into account its context in this Act and the purpose or object underlying the provision, leads to a result that is manifestly absurd or is unreasonable.
