WA Labor will cap the price of train and bus tickets to a standard two-zone fare if it wins the March state election.
This fare relief, to begin in January 2022, will significantly benefit people who live in the Peel region but travel into the CBD every day.
Dawesville residents would save $8.20 on a cash fare per trip to the city, or $6.56 for a Smartrider fare under the new policy, with Mandurah residents saving up to $6.40, or $5.12 for a Smartrider fare.
Cash concession fares to the city will also be capped at $2.10.
Mandurah MP David Templeman said it would save Mandurah families a significant amount of money.
"This policy represents a significant saving to a family that regularly takes public transport into the city and it is something that I am very happy to promote," he said.
"This is a significant saving and will go a long way towards alleviating cost of living pressures for people living south of the cut," Dawesville Labor candidate Lisa Munday added.
Murray-Wellington MP Robyn Clarke said she was delighted to hear this announcement.
"Many people travel to Mandurah to catch the train to the CBD every day," she said.
"I am absolutely delighted to hear about this policy, which will save local families a lot of money."
The reduced fare structure is expected to increase patronage on buses and trains, potentially taking 5300 cars off the roads every day.
The upgraded Smartrider ticketing system will also give passengers the choice of tagging on, using credit and debit cards or smartphones.
