PEXA has completed a major uplift of its digital property settlement and lodgement platform, achieving what it describes as world-class redundancy recovery capability as part of a long-term program to strengthen resilience across Australia’s eConveyancing infrastructure. The enhancement, delivered in partnership with Amazon Web Services, is designed to safeguard national property transactions against disruption while modernising the platform’s underlying technology.
Testing conducted in late 2025 demonstrated that, in the event of a critical disruption such as a software failure or cyber incident, PEXA can now restore data and platform operations in under four hours. The upgraded architecture leverages a multi-Region disaster recovery strategy and an always-on “pilot light” deployment, providing continuous availability and near real-time data replication across AWS’s Sydney and Melbourne Regions.
PEXA Chief Executive Officer and Group Managing Director Russell Cohen said the milestone reflects a multi-year commitment to resilience as a core pillar of the organisation’s role as custodian of national critical infrastructure. “We are laser-focused on improving stability, security and resilience across our ecosystem, and these latest results with AWS underpin this commitment. All-of-data and platform recovery within four hours is a significant achievement and ensures continuity for millions of property transactions nationwide,” he said.
Cohen added that customers would not need to revert to manual or paper-based processes even in the event of a major outage. “We believe proudly that PEXA is effectively the best defence for eConveyancing redundancy. The Exchange already has a proven track record of performance uptime and reliability, and we can now provide Australians with even greater certainty that their property exchange infrastructure remains robust, secure and future-ready.”
The program also leveraged Amazon Q Developer’s agentic AI capabilities to accelerate legacy Java environment upgrades and automate documentation across more than 60 services. PEXA’s engineering teams were able to complete significant transformation work in hours rather than days, supporting the company’s long-term strategy to enhance resilience, improve scalability and modernise its critical systems in line with national infrastructure expectations.
Jamie Simon (pictured), AWS Australia and New Zealand Director for Financial Services, said cloud and AI capabilities are increasingly central to resilience strategies across the financial sector. “The resilience of Australia’s national critical infrastructure is paramount, and we applaud PEXA’s continued commitment and investment to its high resilience standards for its property exchange platform. By leveraging a multi-Region disaster recovery strategy and Amazon Q Developer’s AI-driven code transformation capabilities, PEXA has reduced operational risk and strengthened its recovery posture.”
Simon added that financial institutions globally are prioritising legacy system modernisation to balance security, resilience and innovation. “This type of transformation is a critical prerequisite for financial stability, especially for core systems that are vital to Australia’s economy.”
Beyond redundancy improvements, PEXA’s platform uplift has strengthened its enterprise security posture. Enhancements include improved vulnerability management, tighter identity and access controls, secure-by-design delivery practices, enhanced observability and threat detection, and bolstered business continuity readiness. The company has also integrated a generative-AI-powered assistant to streamline developer workflows and accelerate the release of new platform features.
