Thank you for your question about the pecuniary (money related) interests of members of parliament.
In the House of Representatives, matters to do with pecuniary interests of members are governed by Standing Orders 134 and 231, and by resolutions (decisions) of the House.
House of Representatives Standing Order 134(a) states that, “A member may not vote in a division about a matter, other than public policy, in which he or she has a particular direct pecuniary interest.”
All members are required to list their pecuniary interests in a Register of Members’ Interests. The purpose of this register is to place on the public record members' interests which may conflict, or may be seen to conflict, with their public duty.
