Your Privacy Policy Isn’t Enough Anymore — Now You Have to Prove It

Australian Privacy Act compliance

Byline: Stu Long, CTO, Orro

Key Takeaways

• The Privacy and Other Legislation Amendment Act 2024 has moved the compliance standard from documentation to demonstration: Australian organisations must now actively prove they are managing personal information appropriately, not merely assert that a framework exists.
• Australia’s Privacy Act now requires organisations to treat data minimisation as an ongoing operating obligation, not a remediation project. The legitimate purpose for holding personal data must be defensible at any point in time, not just at the moment of collection.
• The Office of the Australian Information Commissioner has named “excessive collection and retention of personal information” as an explicit 2025–26 regulatory enforcement priority, alongside new enforcement powers introduced in December 2024.
• Organisations holding legacy customer records, expired marketing consent data, or historical transaction logs without a current legitimate purpose are carrying a concrete regulatory liability under the reformed framework.
• A structured Data Lifespan Audit — mapping every personal data category against a defined retention justification and an automated retirement process — is the most actionable starting point for organisations working to bring their data estates into alignment.

What the Privacy Act Reforms Have Actually Changed

For years, the baseline privacy compliance posture for most Australian organisations was manageable: maintain a privacy policy, operate a data register, and respond appropriately when a breach occurred. The Privacy and Other Legislation Amendment Act 2024 — which received Royal Assent on 10 December 2024 and came into force with most provisions applying immediately — has shifted that posture in ways that are more significant than many organisations currently appreciate.

The reforms address 23 proposals from the Government’s response to the Privacy Act Review Report, covering areas including enhanced regulator powers, cybersecurity uplift obligations, a new statutory tort for serious invasions of privacy, and stronger enforcement mechanisms for the OAIC. The regulator now has new civil penalty powers for interferences with privacy, including infringement notices for non-serious breaches, and expanded search and seizure powers. These are not incremental refinements. They represent a material increase in the OAIC’s capacity to act on what it finds.

The practical consequence for organisations is this: the Privacy and Other Legislation Amendment Act 2024 does not simply raise the stakes of a breach event. It raises the standard required before a breach occurs. Organisations are now expected to demonstrate that their handling of personal information is governed by current, defensible legitimate purposes — not just that policies exist on paper. That is a fundamentally different obligation, and it is one that many organisations’ current data environments are not structured to meet.

The Attorney-General’s Department has confirmed that a second tranche of reforms is being progressed, expected to include more substantive changes such as a “fair and reasonable” test for data handling and expanded individual rights. At the time of writing, that legislation has not yet been introduced to Parliament. The reforms already in force are consequential enough to require immediate attention.

Data Minimisation Is Now an Active, Ongoing Obligation

Australian Privacy Principle 11 has always required organisations to destroy or de-identify personal information that is no longer needed for any purpose for which the information may be used or disclosed. What has changed is the enforcement context in which that principle now operates.

The OAIC published its regulatory action priorities for 2025–26 in July 2025, explicitly naming “excessive collection and retention of personal information” as a priority enforcement area. The Privacy Commissioner, Carly Kind, has been direct in her public messaging: 2025 is a significant year for enforcement, and the OAIC is taking an active posture with the new powers available to it.

What this means in practice is that data minimisation is no longer a retrospective cleanup exercise — something undertaken once a year as part of a compliance review cycle, or triggered only by an impending audit. It is an ongoing operating discipline. At any point, an organisation must be able to answer three questions for every category of personal information it holds: What is the legitimate purpose for retaining this data? Is that purpose still current? And what automated process retires this data when the purpose expires?

For large enterprises operating across CRM platforms, marketing automation tools, ERP systems, and third-party data integrations, the operational challenge here is significant. Personal data accumulates across multiple environments, often without a unified view of what is held, under what justification, and when the relevant purpose will expire. The absence of that view is itself a compliance risk, regardless of whether a breach has occurred.

Orro observes that many organisations have robust privacy policies but fragmented data environments — the policy says one thing, the data estate reflects another. Bridging that gap requires visibility first: knowing what you hold, where it lives, and whether the purpose that justified its collection is still live. Without that map, any minimisation programme is working in the dark.

Accidental Data Hoarding Has Become a Regulatory Liability

The concept of “accidental data hoarding” describes something that is almost universal in organisations with significant operational history: the accumulation of personal information that was legitimately collected at one point, but which is now held without a current, defensible purpose. Legacy customer records tied to products that no longer exist. Transaction logs retained beyond any plausible audit window. Marketing consent data for customers who haven’t engaged in years. CRM entries for contacts who left an organisation a decade ago.

Under the reformed obligations, this data is not neutral. Holding personal information without a current legitimate purpose constitutes a failure to meet APP 11 obligations, and the OAIC now has the enforcement tools to pursue that failure with meaningful consequence. Civil penalties under the amended Act can reach AU$3.3 million for companies for interferences that are not classified as “serious” — and the regulator has been explicit about its intention to use those powers.

The retail and financial services sectors illustrate the scale of this risk particularly well, not because they are uniquely exposed, but because the data volumes are large and the retention patterns are deeply embedded. Loyalty programmes often retain complete purchase histories indefinitely, long after any practical use has expired. Payment processors may retain tokenised card data beyond any regulatory or operational necessity. Insurers frequently hold decades of claims records linked to defunct policy numbers. These patterns are common and, in many cases, no one within the organisation has formally reviewed whether the original collection purpose still applies.

Privacy-by-Design Is an Architectural Requirement, Not a Retrofit

Privacy-by-Design means embedding privacy considerations into the architecture of how data is collected, processed, stored, and retired — not as a layer added after systems are built, but as a design constraint from the outset. In practice, this means data classification frameworks, automated retention controls, and discovery tooling capable of identifying personal data assets.

Orro works with organisations that are making this transition — from privacy compliance as a documentation exercise to privacy compliance as an architectural outcome. Learn more about Orro’s Cyber Strategy & Risk Management practice and Compliance & Assurance services.

The Data Lifespan Audit: A Structured Starting Point

For organisations assessing their current position, a Data Lifespan Audit provides the most practically achievable entry point: map every category of personal information against three questions: What is the legitimate purpose? When does it expire? And what automated process retires it?

Demonstrating Compliance Is Now Part of the Obligation

The 2024 reforms changed what it means to be compliant. The question is no longer “do we have a privacy policy?” but “can we demonstrate that we are systematically retiring data that no longer serves a legitimate purpose?”
