On 25 October 2026, Western Sydney International is scheduled to open to passengers. If you live in Campbelltown and want to catch a flight on public transport, your direct option is the new 845 bus. It runs every 30 minutes between 5am and 10pm, seven days a week, via Oran Park, with an advertised journey time of about 66 minutes to the airport. The bus is welcome, and better than nothing. But it is not what this region was promised, writes DR GEORGE GREISS in this opinion piece ahead of the official start of operations at WSI.
In December 2023, as Mayor, I told council that neither the metro from Glenfield nor the north-south line from the airport to Campbelltown-Macarthur had been committed for construction. “Without these connections,” I said, “our community cannot access the new Western Sydney International Airport via public transport.” Bus access has since been introduced, but on opening day Campbelltown will still be waiting for a commitment to build those rail connections.
In June 2024, when Transport for NSW announced this same bus, I told a parliamentary committee it was “inadequate, infrequent and too slow” for the workers who would need it.
Credit where it is due: the push for these lines has been long-running and has crossed party lines. The NSW Government committed to a business case in early 2023. The federal government has committed $1 billion towards preserving corridors for future rail extensions from Bradfield to Leppington and Macarthur. The state and federal governments are also jointly funding a $195 million business case, now under way, into future rail connections in Sydney’s west. Possible stations have been mapped at Oran Park, Narellan, Mount Annan and Macarthur.
That is progress on paper. None of it is a commitment to build.
Meanwhile, the housing is arriving first. The NSW Government has set Campbelltown a target of 10,500 new homes by 2029, about 2,100 a year. Council is doing its part. Average development application determination times fell from 85 days in 2024–25 to 58 days in 2025–26, placing Campbelltown equal second in Greater Sydney and well under the state average of 84 days. Approvals are not what is holding Campbelltown back. Infrastructure is.
I have long supported more homes near stations, but density only works when people can actually use public transport. At the 2016 Census, 66 per cent of Campbelltown residents travelled to work by car, 17 per cent by train and just 1 per cent by bus. The 2021 Census was taken during Sydney’s lockdown, so the next results will be the first real test of whether that has changed.
More homes without the train means more cars on the same roads.
So what should Macarthur ask for now?
A date. A business case is a study, not a decision. It should end in a published construction decision and a timetable.
The corridor, secured. The $1 billion should translate into corridors formally protected and acquired, before development closes off the route.
A better bus in the meantime. Until the train arrives, the 845 is how this community reaches the airport and the jobs around it. It should become the rapid bus that parliamentary committee recommended, with the bus lanes and intersection priority to match.
Macarthur has done more than its share of Sydney’s growth. The airport was meant to bring a new generation of jobs within reach. Right now, they are an hour away by bus. We should hold every level of government to the promise that they won’t stay that way.

Having been involved in the matter of rail access to WSI for over twenty years I very much doubt airport patronage alone would be adequate to justify extending to link to Campbelltown at this juncture.
My analyses show that on average globally rail accounts for only about 20% of total passengers and for WSA about 26%.
As has been shown rail doesn’t even stack up to St Mary’s.
WSI is accessible by an upgraded road system in an arc from Penrith through Parramatta, down to Liverpool and Campbelltown and supported by vast areas of car parking. High quality buses, shuttles and private cars will give better access than even to Sydney Airport.
This is not just about access to an airport, but all the new housing and industry that has been built, or will be built in the future. The developers of Oran Park have been publicising a train station in its glossy brochures for nearly a decade. Premature yes, but needed infrastructure.
Also tourists are not going to rent a car and drive all the way into the Sydney CBD and we shouldn’t expect locals to park their car at huge parking stations at $49 a day.
If we want to be a city of the future, we need to provide easy, regular, sustainable and accessible transport options for everyone. Otherwise WSI will become the Avalon of Sydney.
15 minute city anyone? Western and South Western Sydney needs more efficient public transport than a bus from Oran Park that takes about an hour. Don’t they want to cut the number of cars on the roads anymore? Frankly I’d rather take the quick and easy option of grabbing a train to Mascot.
Why built a airport and there’s no trains to get there – really good planning government.
PS They had five years to make sure that they had trains running to and fro. I lived in Macquarie Fields for fifty years and never seen a project not organise so bad.
Thank you.
This is the reason I left Liverpool, the suburb i grew up in from 5yo to 32 yo.
I moved to the south coast because south west sydney gets told they are getting things and it doesn’t happen for another twenty years.
The bus airport service is useless if travellers have no where to store
suit cases.
We are better off still travelling on the Sydney airport line and it would be a lot quicker then going by road on a bus .
What a white elephant. No support for anyone one living in greater Western Sydney!
WSI Airport 66mins in the bus. Quicker to take train to Kingsford Smith and there are more flight options. Train needed or discount parking before WSI use meets potential.
