Sarah Henderson’s parliamentary expenses for the latest four reported quarters (1 Oct 2025 – 30 Sep 2026): $528,717 (1 Oct 2025 – 30 Sep 2026)

What’s included in these figures

The total for Sarah Henderson is the sum of all expenses charged to Sarah Henderson’s parliamentary office and reported by the Independent Parliamentary Expenses Authority (IPEA) over the latest four reported quarters (1 Oct 2025 – 30 Sep 2026): travel, office facilities and administration, vehicles, communications and other categories. Refunds and credits are netted off, so a category can be negative. Family and nominee travel is included, as in IPEA’s own headline total for a parliamentarian: those claims are attributed to the parliamentarian who made them and shown as their own category, “Family or Nominee Travel”.

Frequently asked questions

Why four quarters instead of one?

Sarah Henderson’s four-quarter total of $528,717 (1 Oct 2025 – 30 Sep 2026) smooths out one-off quarters such as an election period or an overseas trip. The latest single quarter (Jul–Sep 2026) was $182,800, against an average of $132,179 a quarter across the window.

What is the median and how is it calculated?

Why do some parliamentarians claim much more than others?

IPEA says: “When comparing expenditure between parliamentarians, it is important to take into account the parliamentarian’s role, the size of their electorate, and their electorate’s distance from the closest capital city and Canberra.” Sarah Henderson’s largest category over the window was Office Facilities ($173,410).

Is family and nominee travel included?

Yes. Claims for travel by family members or nominees are attributed to the parliamentarian who made them and counted in their total, as in IPEA’s own totals. For Sarah Henderson this came to $481 over the window.
