Overview
- Transport for NSW and NSW Motorways ordered the CPB‑Ghella‑UGL joint venture to resume tunnelling by May 1 or face potential legal action.
- Agencies say a technical solution exists to complete the final 10% of the tunnels and warn they may appoint another contractor if work does not restart.
- Tunnelling has been stalled since March 2024 after a 10‑metre‑wide sinkhole at Rockdale left about 244 metres of the twin tunnels unfinished.
- Premier Chris Minns and Roads Minister Jenny Aitchison said taxpayers should not fund the fix and that the builder must make good on the project.
- The opening target now stands at end‑2028, budget papers put costs near $3.193 billion, and estimates hearings revealed $5 million spent on external legal advice.
