The Claim

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."

Data vs Claim

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.

Big Build — Original vs Current TEI ($m)
Sector Comparison — Is Transport Disproportionate?

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.
