If the relevant interests of a group of persons are essentially similar, they may be referred to throughout the form as a specifically named group if the membership of each group, with the names and addresses of members is clearly set out in paragraph 7 of the form.

• (2) See the definition of "associate" in section 9 of the Corporations Act 2001.

• (3) See the definition of "relevant interest" in sections 608 and 671B(7) of the Corporations Act 2001.
