Testing the $15 Billion Claim
Geoffrey Watson SC's report concluded CFMEU corruption added approximately 15% to Big Build project costs. We test that claim against official Victorian Budget data.
Geoffrey Watson SC's report "Rotting from the Top — The CFMEU in Victoria During the Setka Era" (commissioned by CFMEU administrator Mark Irving KC) concluded that CFMEU-related conduct added approximately 15% to Big Build project costs. His methodology: interviews with civil contractors who reported 10–30% cost increases after the CFMEU displaced the AWU on civil construction. Watson used 15% as a conservative mid-point.
Fair Work Commission general manager Murray Furlong confirmed the estimate was "broadly consistent with information relayed by Victorian officials."
| Metric | Figure | Source |

| Big Build total program | $127,264m | BP4 / project data |
| Watson SC estimated corruption cost (15%) | $19,090m | Watson SC report (2026) |
| Contractor interview range | 10–30% cost increase | Watson SC report |
| Victorian net debt (mid-2025) | $150.9 billion | DTF |
| Annual interest on state debt | $6.8 billion | DTF |
| Fair Work Commission assessment | "broadly consistent" | Murray Furlong testimony |
Watson's report estimates CFMEU corruption added 15% to Big Build costs. Our budget data shows these 12 projects have an actual cost overrun of 66.7% ($50,925m).
If Watson's 15% estimate is applied to the current Big Build program value of $127,264m, the estimated corruption cost is $19,090m ($19.1b). CFMEU corruption is not the only cause of overruns — but the data is consistent with Watson's claim that it is a significant contributing factor.
If CFMEU corruption primarily affects construction-heavy transport projects, we'd expect the transport sector to have a disproportionately higher cost overrun rate compared to other sectors.
