This page covers the 44th and 45th Parliaments in full. The Registers of Senators’ Interests are tabled as combined Senate volumes, and we have not read them into this site yet. An empty register here is our coverage gap — not a record that this senator declared nothing.

Counts of register entries currently declared. The registers record what is held and not quantity or value, so none of these is an amount. One real-estate entry can cover more than one property, so that figure is a floor rather than a count of properties.

Funding returns lodged with the AEC
Only returns that name this parliamentarian are shown. Money declared as given to a party, a branch or an associated entity is not shown here and is not attributable to any individual.
Election returns linked to this member
Returns this member is linked to, newest first. Linking is per return and exact — an election that does not appear here has not been shown to lack one.

Annual member and senator returns are lodged by a small number of parliamentarians: the whole corpus holds 52 of them. Returns lodged by senators are linked to their profiles where the name on the lodged return matches the name we hold for them; where it does not, the return stays here unlinked rather than being attached to a guess. The Registers of Senators' Interests have not been read into this site yet, so a senator can appear here with a funding return and no declared interests beside it, which is a gap in our coverage rather than a record of what they declared. A parliamentarian with no return has not been shown to have received nothing — most never lodge one.
Amounts below the disclosure threshold in force for a given year are not published by the AEC and are absent from these figures. A low total means little was disclosed, not that little was received.
