The Australian government is pushing through the most significant overhaul of the Privacy Act in decades, with the first tranche of reforms already in force and the most impactful changes expected in 2026. If you run a small or medium-sized business in Australia, chances are data privacy isn’t something you think about every day—until something goes wrong. Australia’s Privacy Act reforms for 2025–26 are among the most significant changes to data protection laws the country has seen in decades. While the large enterprises may have teams dedicated to compliance, SMEs may experience the impact most sharply. So, what’s changing, what’s at stake, and can you prepare your SME for 2026 Privacy Reforms without panic?

2025–26 Privacy Act reforms: Why These Matter to SMEs

The proposed reforms stem from growing public concern about data misuse, cybercrime, and high-profile breaches across Australia. The 2025–26 Privacy Act reforms in Australia are coming in tranches. The enforced and forthcoming changes in the Privacy Act redefine liability for SMEs-  

• More accountability for customer data
• Less tolerance for “informal” security practices
• Stronger enforcement with financial consequences
• Individuals no longer need the OAIC to investigate on their behalf. They can take you straight to court for damages, including for emotional distress. – (Ref: The Statutory Tort for Serious Invasions of Privacy; In Force: June 2025)
• If your SME uses Artificial Intelligence (AI) or automated processes affecting an individual’s rights or interests, you will have new legal obligations.
• Size doesn’t matter. All the SMEs that collect personal information will be required to comply with the full Australian Privacy Principles. – (Ref: Australian Privacy Act Reforms to Include Small Businesses)

 Significantly Higher Penalties: You Should Be Aware Of 

The proposed penalties for serious or repeated privacy breaches are expected to rise dramatically, potentially into the millions of dollars, even for smaller organisations. For SMEs, this means:

• A single major breach could threaten business survival

• Directors and decision-makers may face greater scrutiny

• Insurance alone may not be enough to cover liability

The proposed changes apply to all businesses covered by the Privacy Act, but set the tone for the severity of future enforcement. The maximum civil penalty for a corporation found guilty of a “serious or repeated” interference with privacy is now the greater of these three figures: 

• A$50 million
• Three times the value of any benefit obtained from the misuse of the information.
• 30% of the company’s adjusted annual turnover during the relevant period

Mandatory Breach Reporting Changes: SMEs Need Speed to Comply With 

Australia’s Notifiable Data Breach (NDB) scheme already requires companies to notify the OAIC and affected individuals of an eligible data breach that is likely to result in “serious harm.” The coming changes will raise the bar even higher-

Tighter Timeframes for Reporting: Have you updated your data security measures because you won’t have weeks to figure out the scope of an incident? The 2025–26 Privacy Act reforms make it mandatory to have a rapid incident response plan. 

Mandatory Ransomware Payment Reporting: This clause adds another urgent reporting obligation requiring coordination between IT, finance, and legal teams.

What SMEs Must Prepare for to Avoid Penalties: Stay Ahead of the Reforms 

If you succeed in hiring a premier cybersecurity agency with proven expertise in providing compliance solutions to SMEs, you wouldn’t need enterprise-level budgets to be compliant. Here, I list your must-do preparations to avoid penalties proposed by 2025–26 Privacy Act reforms, including- 

• Understanding what data you actually hold
• Reviewing privacy policies
• Strengthening cybersecurity controls
• Preparing a breach response plan
• Training your team to avoid human error
• Developing and rephrasing a rapid incident response plan

Steps To Stay Compliant With 2025–26 Privacy Act Reforms 

For an SME, the best investment right now is a Cybersecurity Maturity Assessment and a Data Governance Review. What should SMEs do to stay compliant with the imposed and proposed 2025–26 Privacy Act reforms? 

Conduct a Data Inventory: Map all personal information you hold. You should implement a data minimisation policy by securely deleting all data you no longer legally require.

Revamp your Privacy Policy: Your policies and consent should be clear, transparent, and compliant with new rules on Automated Decision-Making (ADM) expected to be effective Dec 2026. – (Ref: Automated Decision Making – Navigating automated decisions, ….)

Enforce Multi-Factor Authentication (MFA): The threat of massive A$50M penalties makes robust security mandatory.

Implement a 72-Hour Response Plan: Implement a written Incident Response Plan that clearly assigns roles to assess and notify the OAIC and affected individuals of a serious breach within the tight 72-hour window.
