Since the Auditor General's 2006 review of constituency allowances, the House of Assembly publishes each member's limit and spending. Spending past a limit is the first thing people check.
The Open Contracting Partnership's guide to red flags puts it this way: a red flag is not evidence that anything wrong happened. It points at something that may be worth a closer look.
No member spent more than a published limit in any category, in any year from 2020-21 to 2025-26. The check covered every category that has a limit in the 256 annual detail reports that load; 8 reports linked from the House of Assembly site are broken and could not be checked.
