Work will soon be under way on a temporary car park at Leppington Station.
The temporary car park will provide approximately 250 spaces for commuters while the station's new multi-storey car park is being built.
The car park, which will be delivered by Camden Council on behalf of Transport for NSW, will be located opposite the station on Rickard Road.
"The temporary car park is another step forward in the process to deliver up to 1000 additional permanent parking spaces for customers at Leppington Station as part of the NSW Government's Commuter Car Park Program," Mr Sidgreaves said.
"It will offset the car parking spaces that will be unavailable during construction of the new multi-storey car park."
The temporary car park is scheduled to open around September and parking will be free for public transport customers.
The majority of the existing commuter car park to the south of the station will remain open to customers during construction.
"Delivering infrastructure like the Leppington commuter car park is complex," Mr Sidgreaves said.
"It requires the state government, local councils, land owners and our local community to work together to achieve the best outcomes for the community."
However community campaigner Michael Andjelkovic says the temporary relief for Leppington commuters is not being felt by those at Edmondson Park.
"Six months ago the government said it would provide temporary parking spaces during the construction of the new 2000-space multi-level car park at Edmondson Park Station but there have been no updates," he said.
Work on the new multi-storey car park at Leppington Station is due to commence in the coming weeks and is expected to be completed around the middle of next year.
It will feature 1000 additional parking spaces, free parking for up to 18 hours, additional accessible parking spaces in the station, precinct lift access, road pavement and pedestrian pathway upgrades CCTV, lighting and wayfinding for improved safety and security.
The provision for electric vehicle charging spaces and motorbike parking is also being assessed.
