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