Sydney Metro West is fully-funded by the NSW Government. The NSW Government is investing $12.4 billion over next four years, including $3.2 billion in 2022-23 to support major construction.
 
Premier Dominic Perrottet and Minister for Transport, Veterans and Western Sydney David Elliott today visited the Sydney Olympic Park site today, where major work is starting on the station.
 
Mr Perrottet said the new Sydney Metro West line would provide a vital transport link to a growing Western Sydney and deliver world-class metro services to more communities. 
 
“Our Government is transforming the way that people move around Sydney, investing more than $76 billion in transport infrastructure across the state, including more than $16 billion in Western Sydney alone,” Mr Perrottet said.
 
“The centerpiece of this investment is Sydney Metro, the biggest public transport project in Australia.
 
“Work is now underway to excavate 468,000 tonnes of rock and soil – the equivalent to 78 Olympic swimming pools – to make way for a state-of-the-art metro station at Sydney Olympic Park. 
 
“This new transport link will further reinforce Sydney Olympic Park’s status as a premier events, sporting, and entertainment precinct, supporting the transit of more than 10 million people who visit or stay each year.”
 
Mr Elliott also announced that two mega tunnel boring machines are now on site at The Bays, which will carve out 11-kilometres of twin metro rail tunnels on the Sydney Metro West line. 
 
“Two mega tunnel boring machines located at The Bays have the important job of carving out 11-kilometre twin tunnels from The Bays to Sydney Olympic Park, bringing Sydney’s booming west one step closer to a world-class rapid metro system in their own backyard.” Mr Elliott said. 
 
“When passenger services start in 2030, Sydney Metro will open the door for more people to explore this dynamic destination, providing a major boost for the area.
 
“Enjoying a day out at this sporting and entertainment precinct will be more accessible than ever – a metro train will take you from Parramatta to Sydney Olympic Park in just five minutes, and from the Sydney CBD it will take just 15 minutes.” 
 
Sydney Metro Chief Executive Peter Regan said once the station box is complete, it will be used as the extraction site for four of the six tunnel boring machines used to construct the twin tunnels for Sydney Metro West.
 
“When this fully accessible station is complete it will provide increased capacity for customers during major events, including two dedicated event-mode entrances,” Mr Regan said. 
 
“Sydney Olympic Park metro station will be located to the south of the existing Olympic Park Station and provide easy interchange with the planned Parramatta Light Rail, the T7 Olympic Park Line, and buses.” 
 
Excavation of the station is expected to take around 13 months to complete and will include the installation of 114 active anchors and 467 passive bolts, and 2151 rock bolts to support the station box structure, as digging progresses to a depth of around 27-metres.
 
The excavation work has started on the station boxes for Sydney Metro West stations at The Bays, Burwood North and Sydney Olympic Park. The first tunnel boring machine will arrive at Sydney Olympic Park in late 2024.
