Where Public Money Concentrates
Procurement Concentration and Limited-Tender Leakage Across Australian Government
All figures read from the live Commonwealth contract register on 10 June 2026. Last ingestion 7 June 2026. | 3,933 contracts · $13.19B analysed
This report reads the public record of Commonwealth procurement and surfaces structural patterns in how money is awarded. It is not a report about individual transactions or named parties. It is a government-wide picture of market concentration, competitive bypass, post-award value growth, spending threshold behaviour, and cross-agency supplier positions — drawn entirely from the publicly available contract register.
Every figure is read directly from the register. Nothing is estimated or modelled.
Five Patterns in Commonwealth Procurement
Top 20 suppliers hold 77.97% of total value
Top 20 suppliers hold $10.29B of $13.19B total. The top 3 alone account for 44.4% of spend. The single largest supplier holds 32.74% of all analysed value via one contract — a level of concentration that would trigger competition review in most regulated markets.
- Supplier 1: 32.74% of total spend ($4.32B) — single contract, limited tender, price suppressed
- Top 3 suppliers combined: 44.4% ($5.86B)
- Top 10 suppliers: 65.2% ($8.60B)
- Remaining 3,913 suppliers share 22.0% ($2.90B)
$3.30B (25.0%) awarded without open competition
One in four dollars of Commonwealth procurement analysed bypassed the open market. Defence accounts for 48.6% of its own spend via limited tender ($2.46B). Home Affairs: 11.6% ($575M). Where limited tender is used repeatedly with the same supplier, it functions as a de facto standing arrangement — without the transparency of one.
- Department of Defence: $2.46B by limited tender (48.6% of Defence spend)
- Department of Home Affairs: $575M by limited tender (11.6%)
- Aurecon Group / Defence: 44 limited-tender contracts
- Thales Australia / Defence: 30 limited-tender contracts
- 1,811 limited-tender contracts total across government
$12.71B in post-award amendments across 587 contracts
Contracts regularly grow after award — the amendment reason recorded is "Variation to contract value." This means the price tested at procurement is not the price ultimately paid. Average amended contract value: $9.39M uplift. The largest single post-award uplift cases are in fuel supply and health procurement.
- Viva Energy / Defence: $470M amendment — largest single fuel supply uplift
- GlaxoSmithKline / Health: $431M amendment on vaccine contract
- Norsta North / Defence: $305M amendment on infrastructure contract
- 587 contracts with recorded value amendments
- Average uplift per amended contract: $9.39M
Spending clusters at $74K–$79,999 and $449K–$499,999
Contract values cluster immediately below reporting and approvals thresholds. 57 contracts sit in the $74K–$79,999 band versus 42 in the $80K–$86K band above. 61 contracts sit in the $449K–$499,999 band versus 16 at or above $500K. These distributions are inconsistent with random contract sizing — they are consistent with deliberate threshold management.
- 57 contracts in $74K–$79,999 band vs 42 in $80K–$86K band above the threshold
- 61 contracts in $449K–$499,999 vs 16 at or above $500K
- Defence: 20 contracts in the $449K–$499,999 band, 10 by limited tender
- Confidence rating 0.80 — pattern is consistent but threshold management cannot be confirmed from contract data alone
Same suppliers win repeatedly across multiple agencies
Five suppliers hold concentrated positions across three or more agencies simultaneously — consistent with incumbency advantage and panel lock-in rather than repeated competitive wins. Deloitte entities appear across nine agencies. This is a structural feature of the market, not a finding of individual contract impropriety.
- Datacom Systems: 4 agencies, $163M total
- Accenture: 3 agencies, $92.6M total
- Jones Lang LaSalle: 3 agencies, $72.4M total
- HP PPS Australia: 3 agencies, $47.8M total
- Deloitte (multiple entities): 9 agencies, $39.5M total
