Where, in a proceeding under section 243B against a
person, the Court is satisfied that the narcotic goods in relation to which
the person is alleged to have engaged in a prescribed narcotics dealing or in
prescribed narcotics dealings are goods reasonably suspected of having been
imported into Australia in contravention of this Act, the Court shall, for the
purposes of the proceeding, treat the narcotic goods as narcotic goods which
have been imported into Australia in contravention of this Act unless it is
established to the satisfaction of the Court that the narcotic goods were not
imported into Australia or were not imported into Australia in contravention
of this Act.
