Ground was broken this week to mark the start of construction on the new $32 million Mandurah Station multi-storey car park.

The expanded car park will have three levels with an open-air top deck, and will be built within the existing northern car park’s footprint.

It will add about 700 new bays and increase the station’s overall parking capacity to 1800 bays.

SmartParker machines, and a range of security and safety measures including lighting, CCTV and duress alarms at the lifts will be included.

The project is being undertaken by WA company PS Structures Pty Ltd and is estimated to support up to 120 jobs.          

The new car park is expected to be open in the second half of 2021 and has received 50/50 funding from by the Australian and Western Australian Governments.

More than 70 per cent of Mandurah Station passengers currently travel to the station by car, with the existing car park reaching 90 per cent capacity by 9am on weekdays.

A free, temporary car park has been established off Morfitt Street, but passengers are encouraged to find alternative means to and from the station as overall parking will be reduced during construction.

Federal Member for Canning Andrew Hastie said the lack of sufficient car parking bays at Mandurah Station had been a persistent local problem.

“Funding for this expansion was part of our commitment to the Mandurah community at the last election. I’m very pleased to see that promise becoming a reality."

“Expanding the station car park will make daily life much easier for local commuters and, together with the upcoming Lakelands Station, is a big step towards catering for the public transport needs of our fast-growing community.”

Federal Minister for Population, Cities and Urban Infrastructure Alan Tudge said it would strip hundreds of cars off the road, busting congestion on the corridor to and from Perth.

"Together with a new station at Lakelands, this project will future-proof access to public transport for communities locally and across the Peel region," Mr Tudge said.

"We also know the delivery of crucial infrastructure projects like the Mandurah is essential to supporting jobs and economic growth at this time."
