WESTPAC in Bassendean will shut its doors on September 20.
Customers were sent letters about the closure on August 23.
They will be transferred to the Galleria Shopping Centre branch in Morley, which is 5.7km away, or they can use the bank outlet at the Australia Post Bassendean office, which is 260m away.
The nearest fee-free ATM is 270m away.
A Westpac spokeswoman said it was not a “light” decision.
“Over the past few years we’ve experienced a significant decline in customer transactions undertaken at our Westpac Bassendean branch as more and more local customers are choosing to undertake their banking in different ways, for example digital banking,” she said.
“We take a number of factors into consideration, including usage, location, proximity to other services and community needs.
“As a group, we currently have more than 4.6 million digitally active customers and in the past 12 months less than 2 per cent of transactions were through our branch network, while at the same time over 80 per cent of our customers are now choosing our online and mobile banking services.
“In response to changes in the way our customers are choosing to bank, we have made a decision to close the Westpac Bassendean branch.”
She said Westpac extended its partnership with Australia Post for customers who preferred over-the-counter transactions.
Bassendean MLA Dave Kelly urged Westpac management to reconsider its decision.
“I, like many others in the community, am disappointed that Westpac are walking out on the Bassendean community,” he said.
“I would urge Westpac management to reconsider.
“If they don’t, customers should also vote with their feet.”
A Town of Bassendean spokeswoman said the land was privately owned and the Town banked Commonwealth Bank.
Westpac’s Inglewood branch closed in 2017.
