Tunnel boring machines (TBMs) Daphne and Beatrice have completed their 18-month journey, carving out twin 11-kilometre tunnels, with plans also now approved and progressing on a new metro-oriented town centre above the future Sydney Olympic Park station, as part of the Sydney Metro project.
The 11-kilometre journey, from The Bays to Sydney Olympic Park, has seen more than two million tonnes of material excavated, with 72,456 tunnelling segments also now installed.
Sydney Olympic Park metro station will feature an underground island platform for everyday use, plus two additional side platforms to provide increased capacity during events.
The new metro station will be close to new light rail, pedestrian and cycling routes to help keep people moving around the wider precinct.
Work inside the 200-metre-long, 37-metre-wide, and 27-metre-deep station box at Sydney Olympic Park will now shift to dismantling the TBMs and getting the box ready for station construction.
Meanwhile, work in the tunnels will focus on the completion of cross passages. These passages are a crucial safety feature that allows the movement of passengers between the two tunnels in case of an emergency.

The breakthrough coincides with another major milestone for Sydney Metro West as the Department for Planning, Housing and Infrastructure has approved plans for a new town centre that will create more than 300 new residential dwellings in Sydney Olympic Park.

The station precinct will integrate with the existing public spaces and enhance the destination’s reputation as a premier location for cultural, entertainment, recreational and sporting events, aligning with the broader strategic vision for the area.
Following the approval of these buildings, Sydney Metro will also now seek to change the development plans to provide 190 more residential dwellings in line with the NSW Government’s priority to increase housing supply.
The Sydney Metro West project will double rail capacity between Greater Parramatta and the Sydney CBD. It will make it easier and faster to travel around western Sydney.
