Executive Summary

The Privacy Act 1988 has been substantially amended with key provisions taking full effect in December 2026. These changes significantly impact how Australian businesses must handle personal information—especially when using artificial intelligence (AI) tools like ChatGPT, Claude, Gemini, and Copilot.

Key Changes Affecting AI Usage:

Mandatory breach notification with stricter timelines (72 hours)
Automated decision-making transparency requirements (APP 1.7)
Cross-border disclosure controls when AI tools store data offshore
"Reasonable steps" documentation required to demonstrate compliance
Increased penalties up to $50 million for serious or repeated breaches

1. Understanding the Privacy Act 1988 (Amended 2026)

What Is the Privacy Act?

The Privacy Act 1988 is Australia's primary privacy law. It regulates how organizations collect, use, store, and disclose personal information.

Who Must Comply?

The Privacy Act applies to:

Australian Government agencies
Businesses with annual turnover over $3 million
Health service providers (regardless of turnover)
Some small businesses handling sensitive information
Credit reporting bodies
Tax file number recipients

2. The Australian Privacy Principles (APPs)

The Privacy Act contains 13 Australian Privacy Principles (APPs) that govern how personal information must be handled.

APP 1: Open and Transparent Management

AI Implications: You must disclose if you use AI tools to process personal information and explain how that affects privacy.

APP 6: Use or Disclosure of Personal Information

AI Implications: Using client data to "test" AI tools or allowing AI providers to train models on your data is likely a breach of APP 6.

3. How AI Tools Trigger Privacy Obligations

Common AI Usage Scenarios in Small Business:

Scenario 1: Administrative AI Use (Low Risk)

Example: Using AI to draft a generic welcome email template. Privacy Risk: Low.

Scenario 2: Client Communication (Medium Risk)

Example: Using AI to help respond to a client inquiry email. Privacy Risk: Medium.

Scenario 3: Sensitive Information Processing (High Risk)

Example: Using AI to summarize patient medical records. Privacy Risk: High.

Scenario 4: Shadow AI (Highest Risk)

Example: Staff using unapproved AI tools without business knowledge. Privacy Risk: Highest.

4. The "Reasonable Steps" Standard

The Privacy Act requires businesses to take "reasonable steps" to comply. This includes knowing what AI tools are in use, having an AI Acceptable Use Policy, training staff on AI privacy risks, disclosing AI use in your privacy policy, and using appropriate AI tools.

5. Automated Decision-Making Transparency (APP 1.7)

New Requirement Effective December 2026: Businesses must notify individuals when automated systems (including AI) are used to make decisions that significantly affect them.

6. Cross-Border Data Disclosure (APP 8)

Most AI tools store data on overseas servers. When you paste client information into these tools, you're making a cross-border disclosure. You must notify the individual, identify the country, ensure the recipient provides APP-equivalent protections, and remain accountable.

7. Breach Notification Requirements

A breach is "notifiable" if unauthorized access occurs that is likely to result in serious harm. You must notify the Privacy Commissioner (OAIC) and affected individuals within 72 hours.
