Bank of Sydney is well into one of Australia’s most ambitious community bank digital transformations. Some of the technology being replaced was no longer fit for purpose. But after more than a year of intensive work, the institution is seeing progress.
“Some of our technologies in place were developed before the mobile phone was even invented,” explains Geoff Wenborn, Chief Information Officer at Bank of Sydney. “It’s very hard to retire all that technology when you depend on it for critical banking products.”
Those legacy systems had created significant challenges for an institution with strong community foundations. Bank of Sydney had built its reputation on personal relationships with the Greek and Lebanese communities across Australia. Average loan balances were high and customer loyalty remained strong. But the bank’s fragmented technology had been holding it back from reaching its full potential.
“We’re very strongly relationship-led in terms of the way we've operated, and while there has been investment in technology, it hasn’t been an investment in an integrated fashion so that everything connects together,” Geoff explains.
The impact of these disconnected systems was felt throughout the organisation. Staff had been spending hours on manual processes while customers experienced delays as applications moved between systems. For a bank that prided itself on personal service, these technological barriers were undermining its core strengths.
Geoff, who describes himself as a “serial CIO,” joined Bank of Sydney specifically to tackle this transformation challenge. His mandate was straightforward: modernise everything while preserving the relationship-focused culture that defines the institution.
“The challenge is there to do better for our customers, do better for our employees and support our shareholders,” he says. “We need to implement a better technology environment that is more competitive.”
The urgency of this transformation reflects the broader competitive pressures facing all banks. The transformation is gaining momentum after careful planning and partner selection, driven by the reality of Australia’s fast-moving financial services landscape.
“It is a very competitive environment, the world moves on so it doesn’t wait for us to catch up,” Geoff reveals. “We’re constrained in terms of how much we can invest and the time it takes to drive real change.”
His solution involves replacing decades of accumulated technology debt with an integrated, cloud-first platform. The approach is bold for an organisation with limited resources, but progress is already visible across multiple operational areas.
Cloud partners provide the foundation
Core banking transformations have destroyed careers and bankrupted institutions. The complexity of replacing systems that handle every deposit, loan and transaction has earned these projects the nickname “CEO or CIO killer”. Geoff understands these risks and has designed a gradual approach that avoids disrupting the bank’s critical operations while building momentum through careful partner selection.
The bank has partnered with Infosys for its new core banking platform, moving to a cloud-based software-as-a-service model that represents a fundamental shift from previous approaches. This partnership addresses the bank’s need for comprehensive coverage across all operational areas.
“It was very important to deliver a technology platform that covers all the bank’s needs in terms of meeting regulatory requirements, but all the different channels and services and products,” Geoff explains. “A much more integrated approach was required.”
Beyond integration, the cloud migration is bringing currency with market developments in technology that the bank could never achieve through internal investment alone. “We chose to transition to cloud because that gives us currency and helps as our partners have got much deeper pockets than we have, keeping us more current to market so we don't have to play catch-up ever again,” Geoff says.
This strategic approach also shifts the bank’s financial model from capital expenditure to operational expenditure. The change is providing greater flexibility while accessing capabilities that would be too expensive and take to long to build internally, allowing Bank of Sydney to compete with much larger institutions.
For lending operations, Bank of Sydney has selected Nucleus Software, complementing the core banking transformation with specialised capabilities. The global provider serves financial institutions across Asia, the Middle East and beyond, bringing proven expertise to the bank’s credit operations.
“Nucleus provides an up-to-market cloud-based software-as-a-service model that delivers a great end-to-end lending process,” Geoff reveals. “We haven’t leveraged the full capabilities of Nucleus yet, so we’re very keen to continue that journey.”
The lending platform is already addressing pain points throughout credit operations that had frustrated staff and customers alike. Previously, numerous manual steps had created delays and inefficiencies, but the integrated approach is now streamlining these processes and delivering measurable improvements.
Staff experience transformation
The technology changes are fundamentally altering how people work, with results that demonstrate the transformation's impact on day-to-day operations. The improvements are already visible across different parts of Bank of Sydney, though progress varies depending on process complexity.
“In some of our simpler customer segments, we've created much more time already, but in others where it’s more complex, we still have lots of manual steps which we need to eradicate,” Geoff explains.
This shift is allowing relationship managers to focus on what Bank of Sydney does best: building customer relationships. The change is particularly significant given how much time had previously been consumed by administrative tasks that added little value to customer interactions.
“We’re able to focus some of our bankers much more on the customer rather than doing admin and back-office activity that was built into their roles,” Geoff says. “That prevented them from getting out and speaking to our customers enough.”
These operational improvements come at a crucial time as customer demographics continue evolving. Wealth is transitioning to younger generations who expect digital-first banking experiences, while many customers maintain relationships with multiple banks, creating competitive pressure for service improvements.
The bank's response balances innovation with its traditional strengths. "Our goal is not to be bleeding edge, but to try to make sure that we can be relationship-led, really focus on our key strengths around deposits, business banking, and customer relationships, but uplift the experience with greater efficiency," Geoff explains.
Creating seamless integration
The transformation’s success depends heavily on how well different systems work together, making integration a critical component of the overall strategy. A key element involves implementing Salesforce as the primary customer relationship management platform, which will support the bank’s relationship-focused approach whilst enabling more sophisticated customer analytics.
The technical backbone of this integration relies on MuleSoft, which enables different applications to communicate seamlessly and is creating the automation that eliminates traditional silos. This capability addresses one of the bank’s fundamental challenges: ensuring information flows smoothly between systems.
“We’re leveraging integration through MuleSoft to provide fantastic integration capability,” Geoff explains, “making sure that we can integrate all our business processes end-to-end in a very seamless manner.”
The unified approach represents a dramatic departure from previous operations, where different systems had served specific functions but created barriers when processes spanned multiple platforms. Now, the integrated architecture ensures consistent customer experiences regardless of interaction channel.
Complementing these operational systems, the bank is also implementing Snowflake as its data warehouse platform. This upgrade represents a significant shift in analytics capabilities that will support better decision-making across the organisation.
“We’re uplifting our data warehouse environment with Snowflake, and that’s proving to be a significant shift in terms of how we’re able to analyse and consume information creating a platform for AI and real time reporting,” Geoff reveals.
Strategic partnerships drive progress
Bank of Sydney’s scale means it cannot build large internal IT teams, making strategic partnerships essential to transformation success. The bank is relying heavily on relationships with providers who understand mid-market requirements and can deliver enterprise-grade capabilities at appropriate scale.
Hexaware Technologies is serving as the primary IT services partner through a relationship that has evolved over four years, with scope continuing to expand as the digital transformation progresses into new areas. This partnership exemplifies the bank’s approach to leveraging external expertise.
“Hexaware has been partnering with the bank for almost four years now, but certainly we're looking for more from their services,” Geoff says. “We don’t have the scale to have a big internal IT team.”
The partnership model reflects Bank of Sydney’s pragmatic approach to resource allocation. Rather than attempting to build capabilities internally, the bank is focusing on banking expertise while leveraging partners for technology services that require specialised skills and significant investment.
“We are not necessarily an organisation that can afford the top-end service partners, so Hexaware is really a nice mid-market partner for us,” Geoff explains.
This relationship extends beyond traditional IT support to encompass strategic guidance across the technology landscape. The partnership is helping navigate complex technical decisions while ensuring the bank maintains focus on core banking activities that drive customer value.
Implementation builds momentum
The transformation is following a carefully planned timeline with multiple streams progressing in parallel, designed to minimise disruption while delivering incremental benefits. Core banking implementation should be completed early next year, providing the foundation for subsequent enhancements.
Building on this foundation, the bank also plans to move to the next version of the Nucleus FinnOne Neo lending platform soon after that timeframe. This upgrade will unlock additional capabilities while building on the integration work already completed.
“We’ve got to bet a lot of that down in the first half of next year and then hopefully we'll have it all singing, all dancing by about the end of that period,” Geoff continues.
The phased approach reflects lessons learned from other transformation projects, where attempting too much change simultaneously can overwhelm organisations. Each implementation milestone builds upon previous achievements, creating momentum while managing risk through careful sequencing.
The transformation strategy follows what Geoff describes as a “catch up, keep up, get ahead” philosophy: a move which acknowledges the bank’s current position while establishing foundations for future competitiveness in an increasingly demanding market.
Continuous improvement ahead
Bank of Sydney expects to transition from project-based transformation to continuous improvement once foundational systems are operational, marking a shift from catch-up mode to sustainable innovation. The cloud-based platform will enable regular updates from partners without requiring major internal projects or disruptive implementations.
“Once we’re on that transformed technology capability being cloud-based, our partners will keep delivering us updates to our functionality and technology,” Geoff explains. “In the future, we can just consume that capability uplift without having such a significant investment programme underway.”
This approach ensures the bank can benefit from ongoing partner investments in emerging technologies. Partner investments in AI will become available through the integrated platform, ensuring Bank of Sydney can access advanced technologies without having to resort to direct investment in capabilities beyond its core expertise.
The platform’s benefits extend beyond future innovation to immediate operational improvements.
The modernised infrastructure is improving regulatory compliance through automated reporting and enhanced data management, reducing operational overhead whilst ensuring adherence to evolving requirements.
This improvement frees up resources for customer-focused activities rather than administrative compliance tasks.
Perhaps most significantly, the flexible platform architecture is creating new product development opportunities that were previously impossible.
The bank can now rapidly deploy new capabilities as market conditions evolve, supporting innovation while maintaining operational stability.
“From there, we can move to a continuous improvement model which gives us the best chance of growth,” Geoff concludes.
