Bank of Sydney goes live on Infosys Finacle on AWS

Bank of Sydney has gone live on the Infosys Finacle Digital Banking Suite on AWS, marking a core technology overhaul at the Australian lender.

The rollout includes Finacle Core Banking Solution, Finacle Digital Engagement Hub, Finacle Online Banking and Finacle Mobile Banking in a software-as-a-service model hosted on Amazon Web Services.

The platform forms part of a broader effort to modernise the bank's technology base as Australian lenders update ageing systems to meet changing customer expectations, regulatory demands and competition from digital-first rivals.

The new setup provides a single digital banking platform and reduces the complexity of the IT estate. It is also preconfigured for Australian banking products and processes and connects with other platforms via open application programming interfaces.

This is intended to streamline operations and increase automation across key processes. Bank of Sydney also expects a more efficient operating model for staff and a reshaped customer experience across its digital channels.

Customer services

Customers now have access to real-time processing, faster payments, broader self-service options and integrated online and mobile banking services. The new environment is also designed to support faster product launches while meeting governance, risk and regulatory requirements.

For midsized and challenger banks, replacing core banking systems is often one of the hardest parts of a digital transformation programme because these platforms sit at the centre of customer accounts, payments and compliance processes. Moving them to cloud-based delivery models has become more common as lenders seek to reduce operational complexity and shorten implementation cycles.

Australia's banking market has seen rising investment in platform renewal as institutions pursue more flexible technology stacks. Core modernisation projects are often tied to efforts to improve customer retention, reduce manual work and respond more quickly to changes in product design and policy settings.

Cloud shift

The use of software-as-a-service for core and digital banking reflects a broader shift across the financial sector towards externally managed platforms. Supporters say this model can help banks standardise upgrades and reduce the burden of maintaining legacy infrastructure, though it also increases dependence on technology vendors and cloud providers.

Infosys Finacle said the deployment reinforces its role in banking transformation projects for financial institutions, updating their technology foundations. It has been expanding its work with banks seeking to combine core processing and customer-facing digital services on a single platform.

At Bank of Sydney, the move is positioned as a long-term technology foundation for growth. By consolidating multiple banking functions into a single cloud-based environment, the lender aims to simplify internal systems while providing customers with a more consistent experience across channels.

The implementation also points to the growing role of open interfaces in banking technology strategy. Application programming interfaces are now standard in many modernisation programmes because they allow lenders to connect core systems with payment services, customer tools, and third-party applications without rebuilding the entire stack.

For customers, the most visible impact is likely to be faster transactions, easier digital access and stronger self-service functions. For the bank, the bigger change is behind the scenes: a less fragmented systems environment and a platform that can adapt as products, regulation and customer behaviour change.

The project adds to a broader pattern in Australian banking, where institutions are reassessing the resilience and flexibility of their technology foundations as digital service standards rise. In that context, Bank of Sydney's migration to the Infosys Finacle suite on AWS shows how core banking renewal is moving from long-term ambition to completed delivery.
