Macquarie Bank's transition to being a digital-only financial institution ramps up a notch today as customers won't be able to complete over-the-counter services from its offices anymore. The fast-growing bank kicked off its transition earlier this year and will complete it in November.

From today, customers can't withdraw and deposit cash from the bank's three branches and will have to switch to digital-only payments, which Macquarie said is the preferred method for 99 per cent of its users. The move prompted outrage from some Aussies, with one telling Yahoo Finance banks shouldn't be forcing customers "into electronic, let alone electronic-only, banking or transaction services".

Additionally, depositing or collecting cheques and ordering new chequebooks won't be available from today.

Unlike the Big Four banks, Macquarie doesn't have a huge network of branches dotted around the country.

If customers wanted to put in or pull out cash up until yesterday, they had to visit one of three offices in Sydney, Brisbane or Melbourne.

Under the changes starting today, customers will still be able to withdraw cash from ATMs with their Macquarie card in Australia and overseas and the bank said it will cover ATM cash withdrawal fees.

But they will now have to learn how to do all those other in-person, over-the-counter services online.

Macquarie said customers can find out how to do that here.

"As a digital bank, we're committed to transitioning to completely digital payments by November 2024 as a safer, faster and convenient way to bank," a Macquarie Bank spokesperson said.
