Overview

• CGU, comprising CPB Contractors, Ghella, and UGL, notified Transport for NSW of its decision to terminate the M6 Stage 1 contract, citing unanticipated geological challenges.
• The project has been plagued by delays since March 2024, when two sinkholes emerged in Rockdale due to complex fault zones, halting work for over a year.
• NSW Premier Chris Minns criticized the contractor's withdrawal, urging a return to engineering solutions while warning that alternative contractors may be engaged.
• The motorway’s completion has been pushed to 2028, three years later than planned, with taxpayers already burdened by over $5.5 million in legal fees.
• Transport for NSW maintains that CGU remains responsible for the project’s design and delivery, as officials assess options to restart the stalled construction.
