New multi-storey car park at Mandurah Train Station to create local jobs, 600 more bays

The $32 million project is being jointly funded by the state and federal governments, with a 50-50 split to pick up the bill.

The number of parking bays is set to increase by 600, with construction planned to begin early next year and the project potentially being completed by the end of 2020.

WA Transport Minister Rita Saffioti said the car park was another facet of the state government's METRONET plan.

"The multi-storey carpark was a key commitment and we're pleased to be going to the market to get it built," she said.

"The Mandurah Line has been an incredible success since the day it was planned and built.

"This success has led to increasing patronage from residents in Mandurah and commuters as far south as Bunbury who often struggle to find parking at peak hour."

Canning MP Andrew Hastie said the Commonwealth's contribution was from the Urban Congestion Fund and it was an important project.

"The new car park will be built within the footprint of the existing northern car park and will boost overall capacity from about 1100 bays to about 1700," he said.

"Commuters will no longer have to park on adjacent streets surrounding the station, which has been a source of frustration for local residents."

"I'm pleased to see it getting underway."

Mandurah MP David Templeman said the project was needed due to an increase in commuter numbers.

"Passenger numbers on the Mandurah Line aren't slowing down, with boardings at Mandurah Station alone expected to grow by almost 50 per cent by 2031," he said.

"The thriving service also been a catalyst for huge residential development in the southern suburbs, with many families enjoying the beachside Mandurah lifestyle.

"This $32 million project will help future-proof Mandurah Station as more METRONET projects come online and our public transport network becomes an even more desirable way to travel."

Federal Minister for Population, Cities and Urban Infrastructure Alan Tudge said demand for car parks at Mandurah station will skyrocket in coming years, with daily boardings jumping from 4431 in 2018 to an estimated 6500 by 2031.

Ms Saffioti said she expected the construction of the car park facility would create hundreds of local jobs once the tender was awarded.

When quizzed on the future of a new train station in Lakelands, she said discussions between the state and federal government over the funding split for the project were "ongoing".

The Mandurah open deck car park will be designed to maximise security, natural lighting and ventilation while providing shading and weather protection where possible, with lifts, an open staircase and faade screening.

Once a contractor is selected and works begin, the northern car park will be sectioned-off so the new multi-storey facility can be built.

The Public Transport Authority is investigating options to partially offset the parking temporarily lost during construction, by using adjoining land reserves.
