If:
(a) a committee of persons is authorised by a law of a State or Territory to engage in a quality assurance activity; and
(b) a law of that State or Territory ( the relevant State or Territory law ) that has the same general purpose as this Part would, if this Part had not been enacted, apply to the persons who are members of that committee in respect of that activity;
it is the intention of the Parliament that this Part is not to exclude or affect the operation of the relevant State or Territory law and this Part applies to those persons in respect of that activity only to the extent to which the relevant State or Territory law would not otherwise apply.
