Legal Obligations

Privacy Act Obligations
for Australian Businesses

The Privacy Act 1988 (Cth) imposes ongoing legal obligations on most Australian organisations. Understanding these obligations — and maintaining evidence that you meet them — is essential to avoiding OAIC enforcement action.

This page focuses on the legal duties themselves. If you want a broader overview, start with the Privacy Act compliance guide. If you want to test your current controls against these duties, run a privacy compliance check.

Key definitions

Obligation

A legal or practical duty your organisation must satisfy under the Privacy Act, the APPs, or the NDB scheme.

Evidence

The policies, notices, records, and decision logs that show how you meet those duties in practice.

Compliance check

A practical review that tests your current controls against the obligations listed on this page.

Who has Privacy Act obligations?

The Privacy Act applies broadly. The following categories of organisations have Privacy Act obligations. For a full breakdown of what these obligations require in practice, see our Privacy Act compliance guide.

  • Businesses with annual turnover over $3 million
  • Health service providers (regardless of turnover)
  • Credit providers and credit reporting bodies
  • Businesses that trade in personal information
  • Businesses related to a body corporate that is already covered
  • Federal government agencies
  • Contracted service providers to the Australian Government

Even if your business is not legally required to comply, OAIC guidance recommends voluntary compliance as good business practice. Many contracts, tenders, and enterprise clients require Privacy Act compliance regardless of turnover.

Core Privacy Act obligations

Your obligations under the Privacy Act are structured around the 13 Australian Privacy Principles (APPs). For a detailed breakdown of each principle, see our APP compliance checklist. The following are the key ongoing obligations most organisations must manage:

APP 1

Maintain an open and transparent privacy policy

Ongoing

Your privacy policy must be freely available, current, and describe how you manage personal information. It must be aligned to the APPs and include complaint procedures.

APP 3 & 4

Limit collection to what is reasonably necessary

Only collect personal information that is reasonably necessary for your functions. Have processes for handling unsolicited personal information that does not meet this test.

APP 5

Notify individuals at the point of collection

Provide a collection notice at or before the time of collection, covering who you are, why you are collecting, who you share it with, and how individuals can access it.

APP 6

Use and disclose for the primary purpose

Ongoing

Use personal information only for the primary purpose of collection, or for a related secondary purpose the individual would reasonably expect. Direct marketing has additional consent requirements under APP 7.

APP 8

Manage cross-border disclosures

Ongoing

Before sharing personal information with overseas recipients, take reasonable steps to ensure APP-equivalent protection. You remain accountable for how overseas recipients handle the data.

APP 11

Secure personal information

Ongoing

Take reasonable steps to protect personal information from misuse, interference, loss, and unauthorised access. Destroy or de-identify when no longer needed.

APP 12 & 13

Respond to access and correction requests

Ongoing

Individuals have the right to access their personal information and request corrections. Have documented procedures and respond within required timeframes.

NDB Scheme

Notify eligible data breaches promptly

Ongoing

Assess suspected breaches and notify the OAIC and affected individuals without unreasonable delay (and within 30 days) if serious harm is likely.

You can generate an APP‑compliant policy instantly using our privacy policy generator.

Notifiable Data Breaches (NDB) obligations

The NDB scheme creates a specific set of time-sensitive obligations when a data breach occurs. These obligations apply independently of the other APPs. Learn more about how this fits into your broader compliance duties in our Privacy Act compliance guide.

1
Contain and assess

Take immediate steps to contain the breach and assess whether it meets the threshold of "eligible data breach" (likely to result in serious harm).

2
Notify within 30 days

If the breach is eligible, notify the OAIC and affected individuals as soon as practicable — the OAIC expects notification within 30 days of becoming aware.

3
Prepare an OAIC statement

The OAIC statement must describe the nature of the breach, the information involved, and the steps taken in response.

4
Document everything

Maintain a complete breach record including the assessment, notification, and remediation steps. This is evidence of your compliance with the NDB scheme.

Privacy Impact Assessment obligations

Privacy Impact Assessments (PIAs) are mandatory for certain federal agencies and for initiatives with specific Privacy Act impacts. For private organisations, PIAs are best practice and increasingly expected by enterprise clients and regulators. For a full overview of your Privacy Act responsibilities, see our Privacy Act obligations guide.

OAIC guidance recommends conducting a PIA when you:

  • Introduce a new system, application, or digital product that handles personal information
  • Adopt new data sharing arrangements with third parties
  • Significantly change an existing process involving personal information
  • Implement new surveillance, tracking, or profiling capabilities
  • Move personal information to a new cloud service or overseas provider

Evidencing your Privacy Act obligations

Compliance is not just about having the right policies — it is about being able to demonstrate that you meet your obligations. For a structured approach to evidencing each APP, see our APP compliance checklist. The OAIC expects organisations to maintain records showing:

  • When and how privacy policies were updated
  • What APP gap assessments found and how gaps were remediated
  • How cross-border disclosure decisions were made and documented
  • The complete timeline and handling of any data breach incidents
  • Human sign-off on key compliance decisions

Privacy Act Shield's Evidence Vault maintains a structured audit trail of every compliance decision, sign-off, and change — ready for OAIC review.

Frequently asked questions

For a complete overview of your responsibilities, see our Privacy Act compliance guide and APP compliance checklist.

What are my Privacy Act obligations as an Australian business?

Your core obligations include maintaining an accessible privacy policy, notifying individuals of data collection, limiting collection to necessary information, securing personal data, providing individuals access to their records, and notifying the OAIC of eligible data breaches.

What is the NDB notification obligation?

Under the NDB scheme, you must notify the OAIC and affected individuals as soon as practicable (and within 30 days of becoming aware) when a data breach is likely to result in serious harm. Failing to notify is itself a breach of the Privacy Act.

When must I conduct a Privacy Impact Assessment?

PIAs are mandatory for certain federal agencies. For private organisations, OAIC guidance recommends PIAs before introducing new systems, data types, or third-party integrations that handle personal information.

What are the cross-border disclosure obligations under APP 8?

Before disclosing personal information to an overseas recipient, you must take reasonable steps to ensure APP-equivalent protection. You remain accountable if the overseas recipient mishandles the data.

Meet your Privacy Act obligations with confidence

A Privacy Advisor will map your obligations and build the evidence you need to demonstrate compliance. You can also review APP compliance requirements before your session.
