It is a sign of how tortuous a technology overhaul inside a major bank can be that Westpac’s big reveal today on its own program was foreshadowed more than a year ago.
In March 2025, Capital Brief unearthed the news that Westpac's then new CEO, Anthony Miller, was reassessing the future of its major sub-brands — St. George Bank, Bank of Melbourne and BankSA — as part of its Unite tech overhaul.
Now the bank has finally taken concrete steps in that direction, announcing that about 75,000 commercial customers from those sub-brands will be migrated to the mothership by 2027.
The Unite program aims to consolidate and rationalise Westpac's sprawling banking infrastructure, which comprises about 85 systems after three decades of acquisitions.
