A booming scaffolding firm that has secured significant contracts on the $550 million redevelopment of the nation’s war memorial, the Sydney Metro, a major hospital and a public school has been repeatedly promoted by the CFMEU, despite a catastrophic safety record and alleged links to a bikie boss and other underworld figures.

Synergy Scaffolding Services and its related entities have not only secured union backing for multiple enterprise bargaining agreements (EBAs) but, according to union and industry sources, been repeatedly informally pushed by sacked NSW CFMEU boss Darren Greenfield onto work sites around the state.
