590.This section allows the Authority to make rules requiring professionals carrying on exempt regulated activities to disclose to their clients that they are not authorised.  It also requires the professional bodies to make rules designed to ensure that those members who benefit from the exemption will not carry on regulated activities which are not complementary to the provision of particular professional services to a particular client, although this does not extend to regulated activities conducted by professional firms as exempt persons under the Act.  In order to be effective, those rules must be approved by the Authority.
