Westpac Consolidates St George, BankSA, and Bank of Melbourne Under Single Brand
Westpac is set to embark on a significant strategic move, consolidating the commercial banking operations of its subsidiary brands – St George Bank, BankSA, and Bank of Melbourne – under the unified Westpac banner. This ambitious plan is slated for completion by December 2027, marking a pivotal moment in the bank’s ongoing technological transformation.
The consolidation is a key component of Westpac’s broader technological upgrade program, codenamed “Unite.” According to Westpac Chief Executive Anthony Miller, the “one commercial bank” project aims to streamline the bank’s complex technological infrastructure, including the decommissioning of its legacy Hogan system and other outdated platforms.
“As part of this migration, commercial business banking customers and employees from St George, BankSA, and Bank of Melbourne will transition to a consistent banking experience and single brand under Westpac,” Miller explained. This strategic shift promises to equip these businesses with enhanced digital capabilities and a wider array of products and services. Customers can anticipate access to real-time payments, more flexible merchant solutions, and Westpac’s award-winning banking app.
The “one commercial bank” initiative is a substantial undertaking, involving the migration of over 75,000 commercial customer accounts to the Westpac platform. The projected cost for this endeavour is approximately $230 million, with the bank anticipating annual benefits of around $40 million commencing in the 2028 financial year (FY28).
Unite Program: A Deep Dive into Westpac’s Tech Overhaul
The Unite program, Westpac’s comprehensive technological modernisation effort, is progressing steadily. In the first quarter, the bank reported an investment of $195 million in Unite, placing it firmly on track to achieve its projected spend guidance of between $850 million and $950 million.
“We expect Unite to represent approximately 40% of annual investment spend in FY27-FY28 before stepping down at FY29,” Miller noted, highlighting the program’s significant, albeit temporary, impact on the bank’s investment allocation.
The Unite program encompasses a vast array of 57 distinct initiatives, with eight of these having already reached successful completion. To manage the progress of these initiatives, Westpac has implemented a traffic light system. Currently, 38 initiatives are classified as ‘green’ (on track), seven are ‘amber’ (requiring attention), and one is ‘red’.
The single ‘red’ initiative pertains to the bank’s debit card simplification project. While acknowledging unforeseen challenges, Westpac has stated that “clear actions” are in place to steer this project back onto its intended course.
Key Milestones and Future Outlook
In a significant achievement for the Unite program, Westpac successfully migrated its wealth customers to BT Panorama this month. This migration has resulted in the platform now housing over 300,000 accounts and managing more than $150 billion in funds under administration.
Looking ahead, Westpac has outlined several key milestones for the second half of the 2026 financial year (2H26):
- Mortgage Simplification: This includes the crucial transfer of Westpac mortgage property security data to the target state master and the enablement of an SMSF product on the Westpac mortgage ledger.
- Digital Banker Platform Updates: Enhancements to the bank’s digital tools for its banking professionals.
- Personal Loans and Regional Brand Credit Card Migration: Moving these products to the AssistNow platform.
- Debit Card Simplification Initiatives: Progress on the project previously flagged as ‘red’.
- One Commercial Bank: The foundational work for the consolidation of commercial banking operations.
Furthermore, Westpac anticipates the completion of its “one business deposit ledger” migration, another significant component of the Unite program, by the first half of the 2028 financial year (1H28).
The strategic moves and technological advancements underscore Westpac’s commitment to modernising its operations, enhancing customer experience, and driving future growth. As of 11:27 pm AEDT, Westpac shares showed positive momentum, trading 0.89% higher at $40.74.
