Primer — source audit (numbers)
Companion to A Primer on Australian Politics. Use this file when reviewing whether cited figures are confirmed, rounded, outdated, heuristic, or inconsistent with other primer text.
How to use this audit
| Column | Meaning |
|---|---|
| Fact | What the primer claims |
| Figure (primer) | Number as printed in primer.md |
| Source (checked) | Primary or best available reference used in this pass |
| Official / alternate figure | What the source actually says (if different) |
| Judgement | See scale below |
Judgement scale
| Judgement | Meaning |
|---|---|
| Confirmed | Matches an authoritative source within normal rounding |
| Confirmed (structural) | Fixed by law or constitution — not a statistical estimate |
| Confirmed (rounded) | Source supports the order of magnitude; primer rounds or uses “~” |
| Outdated | Primer note is plausible but a newer official figure differs materially |
| Heuristic | Rule-of-thumb or analyst estimate — not a single official statistic |
| Unverified | Not checked against a primary source in this pass |
| Internal calc | Derived only from other primer figures (no external source) |
| Inconsistent | Conflicts with another table or paragraph in the same primer |
Maintenance workflow
- When changing a number in
primer.md, update the matching row here in the same PR. - Prefer primary sources: AEC, Budget Paper No. 1, state budget papers, ABS, parliament websites, ALGA.
- Record audit date and URL in Source (checked).
- For full-document coverage, extend sections below (Part 2, 3, …) using the same table format.

| Federal elected representatives | 227 | Constitution s24 (HoR); s7 (Senate); current seat count | 151 HoR + 76 Senate = 227 | Confirmed (structural) |
| State and territory elected representatives | ~620 | Sum of seats in primer Part 3 parliament column (see below) | Part 3 sums to 620 MPs (all chambers) | Confirmed — internal sum; corrected 2026-05-30 |

Part 1 narrative paragraph (line below table)
| Fact | Figure (primer) | Source (checked) | Official / alternate figure | Judgement |
|---|---|---|---|---|
| Federal + state/territory elected individuals | ~847 | See rows above | 227 + 620 = 847 | Confirmed — internal calc |
| Annual public expenditure (federal + state) | ~$1.2 trillion | See federal + state budget rows | $767b + $403b ≈ $1.17t | Confirmed (rounded) — corrected 2026-05-30 |
Cross-check: Part 3 parliament seats (explains 530 vs 620)
Primer Part 3 lists elected members per jurisdiction. Summing the Parliament column:

|---|---|---|
| NSW | 135 | |
| Victoria | 128 | |
| Queensland | 93 | |
| Western Australia | 95 | |
| South Australia | 69 | |
| Tasmania | 50 | |
| ACT | 25 | |
| Northern Territory | 25 | |
| Total | 620 |
Primer now uses ~620 in Part 1 and Part 3 prose, matching the seat table sum. Federal + state total ~847 (227 + 620).
