TL;DR: Australian financial services now has 532 OAIC breach notifications in the first half of 2025, with 14% attributed to financial services, AvePoint reports. Data governance has to stay aligned to ownership, lineage, and enforcement if resilience and trust are to hold up under operational pressure.
Editorial analysis by NHI Mgmt Group, based on content published by AvePoint: “CPG 235 in Action: Practical Ways for Australian Financial Organisations to Treat Data Strategically”.
By the numbers:
- In the first half of 2025, the OAIC recorded 532 data breach notifications.
- The financial services industry accounted for 14% of incidents recorded by the OAIC in the first half of 2025.
Key questions
Q: What are the signs that data governance is failing in a financial services environment?
A: Common signs include duplicate and derivative data spreading across systems, inconsistent classification, incomplete inventories, overexposed records, and data moving without clear controls.
Q: What are the signs that data governance is not keeping pace with APRA expectations?
A: Common signs include unclear ownership, manual exception handling, inconsistent retention rules, weak lineage visibility, and access approvals that are not tied to the data lifecycle.
Q: How should organisations govern data across its lifecycle?
A: Organisations should treat governance as a chain of controls across acquisition, storage, transfer, retention, and disposal.
Practitioner guidance
- Define lifecycle ownership for critical data Assign named owners, custodians, and stewards to capture, processing, retention, publication, and disposal decisions so governance has accountable control points.
- Map lineage for regulated data sets Build traceability for where critical data originates, how it changes, and which systems consume it so assurance can follow the data path.
- Automate classification and retention enforcement Apply policy controls automatically across hybrid repositories so sensitive data is tagged, retained, and disposed of consistently.
Bottom line: Data governance in financial services now carries resilience and trust implications, not just compliance obligations.

Data governance is now a control plane, not a records function. CPG 235 shows that financial organisations cannot treat governance as documentation layered on top of operations. The real issue is whether data decisions are enforced at the point of use across capture, processing, retention, publication, and disposal. That makes governance a live control surface rather than a back-office policy exercise. Practitioners should manage it as part of the security architecture.
A question worth separating out:
A: Prioritise the strictest data handling requirement and make the agent inherit that constraint through policy, not through manual exception handling. Where access, sensitivity, and regulatory context do not align, the safe default is to restrict retrieval and disclosure until the combined risk is resolved. That approach is closer to enforceable governance than post-hoc review.
