The commuter chaos at Leppington Station is set to be eased with the state government committing to the creation of 1000 new car spaces.
The state government promised earlier in the year to deliver 350 new spaces, and the new announcement of 650 will build on that.
Camden MP Peter Sidgreaves said the announcement addressed ongoing community concerns about the level of parking at the station.
"We know that customers in the Camden electorate and in Sydney's south west have been calling for more commuter car parking and earlier this year the government committed to delivering an extra 350 spaces at Leppington Station," he said.
"The great news is that after further site investigations, planning and working with Camden Council, we can now commit to building even more spots for those customers who need to drive to a station before jumping on a train. Customers at Leppington Station will benefit from around 1000 extra spaces which is around 650 more than the initial commitment."
Works on the new parking spaces are expected to start in mid 2020 and finish in mid 2021. There are already about 800 parking spaces at the station.
Camden mayor Theresa Fedeli welcomed the news.
"This announcement by Peter Sidgreaves and the NSW Government is a win for our residents," she said.
"The extra 1000 parking spaces to be created will no doubt ease the pressures on local commuters.
"Since Leppington Station has been up and running, we've had local residents, schools and businesses tell us they need more parking.
"I've taken this feedback and have been advocating for these much-needed extra parking spaces for some time now, so it's great to hear there will be approximately 650 more spots than the initial commitment."
Cr Fedeli she had met with Planning Minister Rob Stokes and Transport Minister Andrew Constance throughout the year, where she spoke about several issues impacting the Camden area. One of which was the station's parking needs.
"The Camden area is the fastest growing local government area in the country, where we are welcoming more than 100 new residents every week," she said.
"The opportunity to shape the area's growth and development is here now, so it's a priority of mine, and of the council's, to actively advocate for these issues on behalf of the community."
