Public interest director appointment requires prior board approval, cooling off restrictions, limited terms and sitting fee remuneration. Regulation 24 requires prior Board approval for appointment and re-appointment of non-independent and public interest directors, prescribes fixed terms with review and renewals, imposes cooling off rules for subsequent appointments across recognised entities (with special treatment for competing entities and parent subsidiary relationships), restricts simultaneous directorships and committee memberships, mandates conflict disclosure, limits remuneration for public interest directors to sitting fees, and directs applications to follow Part H of Schedule II.
