About these numbers

Based on 766 tracked bills from the 47th and 48th Parliaments, current to 6 July 2026. This is a sample of parliamentary activity, not the complete record.

Career markers come from dated public records. Voting figures use division lists only. For party members, the left-to-right marker begins at the party position. It moves only when the member votes against that party and on the same side as a neighbouring party; other cross-party combinations do not affect it. Independents and minor-party members are placed by their votes in divisions where the Greens and the Coalition took opposite sides. If this position differs from a member’s broader public politics, a note appears below the strip.
