Six train stations would be built in south-west Sydney under a long-term plan to upgrade public transport in the region and to a Badgerys Creek airport.
Transport Minister Gladys Berejiklian will release on Monday a consultation package for an extension of the south-west rail link through the Badgerys Creek airport site, but also further south to Oran Park and Narellan and north to St Marys.
The government is not proposing to build the new lines soon but says it wants to preserve the corridors so they can be more easily built in the future.
The federal government, which has promised to build an airport at Badgerys Creek, says it should be operational by the middle of the next decade.
There will be no train line to the airport when it opens but federal Transport Minister Warren Truss has said the airport should be designed to accommodate a train line in the future.
Ms Berejiklian said buses would be able to satisfy the demand for public transport when the airport opens. The government's projections show the airport would initially carry about 3 million passengers a year, about the same as Canberra and Hobart.
“Longer term, we are putting plans in place to make sure Sydney’s rail network will connect Badgerys Creek airport with the rapidly growing communities that will rely on it,” Ms Berejiklian said.
The south-west rail link, which runs from Glenfield to Leppington, is due to open next year. In the past five years, the suburb of Oran Park has developed faster than the area immediately adjacent to the new line, and Narellan is also set for a major expansion.
But under the government's corridor plans, new stations could be built at these suburbs for a train line that could also extend north to connect to the main western line at St Marys.
Other stations the government is proposing are at Rossmore, Bringelly and North Bringelly.
“We’ve seen previous growth centres of Sydney let down by insufficient transport planning by previous governments and we’re not making that mistake in greater south-west Sydney," Ms Berejiklian said.
Consultation over the proposed corridor and stations will run for the next six weeks. The government will also hold community information sessions on the proposed corridor.
The federal government has said it will not fund train lines to a Badgerys Creek airport but will fund up to 80 per cent of major road upgrades near the airport.
