“Section 6DD of the Act provides that, where a witness is compelled by a summons to give evidence to the Royal Commission, that evidence isn’t admissible against a natural person in any civil or criminal proceedings in any court of the Commonwealth, or of a state or territory. It is, however, admissible against a corporation. ”

However, evidential immunity under s 6DD doesn’t protect clients (who have been compelled to give evidence to the Royal Commission) from a regulator, such as ASIC, using their evidence as a springboard to gather secondary or derivative evidence, and using that derivative evidence against them.
