    Two Privacy Frameworks

    Australian businesses may need to comply with both the Privacy Act 1988 (Australia) and the General Data Protection Regulation (GDPR - European Union). Understanding both is essential for businesses operating internationally.

    The Australian Privacy Act

    Who It Covers

    The Privacy Act applies to:

    • Australian Government agencies
    • Businesses with annual turnover over $3 million
    • Health service providers
    • Businesses that trade in personal information
    • Credit reporting bodies and credit providers
    • Certain other specified organisations
    Small businesses under $3 million are generally exempt, though some activities bring them into scope.

    Key Requirements

    The Australian Privacy Principles (APPs) require:

    CollectionOnly collect necessary personal information with transparency about purpose.
    Use and disclosureUse information only for collected purpose unless consent obtained.
    Data qualityTake reasonable steps to ensure accuracy and completeness.
    Data securityProtect against misuse, interference, loss, and unauthorised access.
    Access and correctionAllow individuals to access and correct their information.
    Cross-border disclosureRequirements when sending data overseas.
    Notifiable data breachesReport eligible breaches to OAIC and affected individuals.

    Enforcement

    The Office of the Australian Information Commissioner (OAIC) enforces the Privacy Act:

    • Investigation powers
    • Enforceable undertakings
    • Civil penalties up to $50 million for serious breaches

    The GDPR

    Who It Covers

    GDPR applies to:

    • Organisations established in the EU
    • Organisations outside the EU that offer goods/services to EU residents
    • Organisations that monitor behaviour of EU residents
    Australian businesses with EU customers may fall within scope.

    Key Requirements

    GDPR requirements include:

    Lawful basisProcessing requires valid legal basis (consent, contract, legitimate interest, etc.).
    TransparencyClear, accessible information about processing.
    Purpose limitationData used only for specified purposes.
    Data minimisationCollect only what is necessary.
    AccuracyKeep data accurate and up to date.
    Storage limitationRetain only as long as necessary.
    SecurityAppropriate technical and organisational measures.
    AccountabilityDemonstrate compliance actively.
    Individual rightsAccess, rectification, erasure, portability, objection.
    Breach notificationReport breaches within 72 hours.
    Data protection officerRequired for certain organisations.
    Data protection impact assessmentsFor high-risk processing.

    Enforcement

    EU data protection authorities enforce GDPR:

    • Investigations and audits
    • Corrective measures
    • Fines up to €20 million or 4% of global annual turnover

    Comparing the Frameworks

    Scope and Application

    Privacy ActGenerally businesses over $3M turnover in Australia.
    GDPRBroader, based on where data subjects are located, not where business is.
    GDPR has extraterritorial reach that can capture Australian businesses dealing with EU residents.

    Consent Requirements

    Privacy ActConsent is one basis for collection and use, but not the only one.
    GDPRConsent must be freely given, specific, informed, and unambiguous. Higher standard.
    Both require consideration of consent, but GDPR is more prescriptive.

    Individual Rights

    Privacy ActAccess and correction rights.
    GDPRBroader rights including erasure ("right to be forgotten"), portability, objection.
    GDPR provides more extensive individual rights.

    Breach Notification

    Privacy ActNotify OAIC and affected individuals for eligible data breaches "as soon as practicable."
    GDPRNotify supervisory authority within 72 hours; notify individuals without undue delay for high-risk breaches.
    GDPR has stricter timing requirements.

    Data Protection Officers

    Privacy ActNo requirement.
    GDPRRequired for certain organisations (public authorities, large-scale monitoring, special category data).

    Data Transfer

    Privacy ActReasonable steps to ensure overseas recipients comply with APPs.
    GDPRStrict requirements for transfers outside EU, requiring adequacy decisions or appropriate safeguards.
    GDPR is more restrictive on international transfers.

    Penalties

    Privacy ActUp to $50 million for serious or repeated interferences.
    GDPRUp to €20 million or 4% of global turnover.
    Both can impose significant penalties.

    Practical Compliance

    Determine Applicability

    Assess which frameworks apply:

    1. Does your business fall under the Privacy Act? 2. Do you offer goods/services to EU residents? 3. Do you monitor behaviour of EU residents? 4. What personal information do you handle?

    Implement Common Controls

    Many requirements overlap:

    • Privacy notices explaining data handling
    • Consent mechanisms where required
    • Data security measures
    • Access and correction procedures
    • Breach detection and response
    • Staff training
    • Data minimisation and retention practices

    Address GDPR-Specific Requirements

    If GDPR applies:

    • Document lawful basis for processing
    • Implement additional individual rights
    • Prepare for 72-hour breach notification
    • Consider data protection officer requirement
    • Address international transfer requirements
    • Conduct data protection impact assessments where required

    Documentation

    Both frameworks expect documentation:

    • Privacy policies
    • Processing records
    • Consent records
    • Breach response procedures
    • Training records
    • Security measures documentation

    For Small Businesses

    Even If Exempt from Privacy Act

    Good practice regardless:

    • Basic privacy practices build trust
    • Prepares for growth or scope changes
    • May be required by customers or partners
    • Reduces risk of problems

    If Dealing with EU Customers

    Consider GDPR implications:

    • May need to comply regardless of size
    • Risk assessment for EU activities
    • Proportionate compliance measures
    • Consider whether EU market is worth the compliance burden

    Proportionate Approach

    Scale to your situation:

    • Larger operations need more formal programs
    • Small operations can implement basics
    • Focus on high-risk areas first
    • Improve over time

    Common Mistakes

    Assuming Exemption

    Assuming rules do not apply:

    • Small business exemption has exceptions
    • GDPR applies based on customers, not size
    • Even exempt organisations should follow good practice

    Consent as Default

    Relying on consent for everything:

    • Other lawful bases may be more appropriate
    • Consent must be genuine and withdrawable
    • Over-reliance on consent creates problems

    Ignoring International Aspects

    Not considering cross-border implications:

    • Where are customers located?
    • Where does data flow?
    • What laws apply in each jurisdiction?

    Treating Compliance as One-Time

    Set and forget:

    • Both frameworks require ongoing compliance
    • Regular review and updates needed
    • New processing activities need assessment

    Getting Help

    When to seek professional advice:

    LegalComplex compliance questions, specific obligations, breach response.
    TechnicalImplementing security controls, data mapping, technical compliance.
    ConsultingBuilding compliance programs, gap assessments, training.
    Both privacy frameworks protect individuals while enabling legitimate data use. Understanding and complying with applicable requirements protects your business and builds trust with customers.
