Navigate privacy regulations protecting customer review data across Australian businesses
Australian businesses collecting customer reviews must comply with the Privacy Act 1988 and understand GDPR implications if they operate internationally. While GDPR is European legislation, Australian companies handling EU customer data face legal obligations that directly impact how they collect, store, and display online reviews. Non-compliance can result in hefty fines and reputational damage.
Yes—absolutely. The GDPR applies to any organisation processing personal data of EU residents, regardless of where your business is located. If you're a Melbourne-based tradies network, Sydney e-commerce store, or Brisbane hospitality venue collecting reviews from international customers, you're potentially handling EU personal data.
According to the Australian Information Commissioner's Office (OAIC), data protection compliance has become a critical business risk. The GDPR's extraterritorial reach means Australian SMEs can't ignore European privacy standards.
Customer review data includes more than just names and email addresses:
Even anonymised reviews can be considered personal data if individuals are identifiable through context or metadata.
Australia's primary privacy legislation is the Privacy Act 1988, which includes the Australian Privacy Principles (APPs). These principles govern how organisations collect, use, disclose, and store personal information.
Key APPs relevant to customer reviews:
The OAIC reported in 2024 that privacy complaints increased 23% year-on-year, with data breaches affecting small-to-medium businesses most severely.
While both frameworks protect personal data, GDPR is significantly stricter:
| Aspect | Australian Privacy Act | GDPR | |--------|----------------------|------| | Consent Model | Opt-out often acceptable | Explicit opt-in required | | Data Subject Rights | Limited access rights | Extensive (right to be forgotten, data portability) | | Breach Notification | No mandatory timeframe | 72 hours mandatory | | Penalties | Up to AUD $2.5 million | Up to €20 million or 4% global revenue | | Scope | Australian residents primarily | Any EU resident data |
Start by mapping where customer review data flows through your business:
A Sydney-based plumbing company discovered they were storing customer phone numbers and addresses with reviews for 5 years—far longer than necessary. By conducting an audit, they reduced retention to 12 months and deleted unnecessary fields.
For GDPR compliance, you need explicit, informed consent before collecting review data from EU customers.
Best practice approach:
Australian businesses using Trustpilot or Google Reviews should verify these platforms have appropriate consent mechanisms for EU users. If they don't, you may need additional consent collection on your own website.
Don't keep review data longer than necessary. GDPR's "storage limitation" principle requires deletion when data is no longer needed.
Recommended retention periods:
A Melbourne retail business implemented automated deletion of IP addresses after 6 months, significantly reducing their data breach risk.
Both the Privacy Act and GDPR require reasonable security measures. For review data, implement:
The OAIC's 2024 Privacy Breach Report found that 67% of breaches affecting Australian small businesses involved inadequate access controls—a preventable issue.
If you discover a breach involving EU customer data, GDPR requires notification within 72 hours. Australian law has no mandatory timeframe, but the Privacy Act still requires prompt action.
Your breach response should include:
A Brisbane-based skincare retailer sells to 40 countries, including Germany and France. They collect reviews through their website and Trustpilot.
Compliance action: They added a GDPR-specific consent banner for EU visitors, implemented a 12-month data retention policy for non-EU customer data and indefinite (with consent) for EU customers, and trained staff on EU data subject rights requests.
A Sydney electrician collects reviews via Google and Facebook from local customers. Occasionally, international visitors leave reviews.
Compliance action: They verified Google and Facebook's consent mechanisms for EU users, implemented a simple privacy notice on their website, and created a process for responding to data access requests within 30 days.
A Perth hotel collects guest feedback including names, room numbers, and stay dates. They use this data for service improvements and marketing.
Compliance action: They separated marketing data (requires explicit opt-in) from service feedback, implemented secure deletion of room numbers and dates after 12 months, and created a guest privacy notice at check-in.
1. Assuming GDPR Doesn't Apply If you have any EU customers, GDPR applies. Don't assume you're too small or local.
2. Pre-Ticked Consent Boxes GDPR requires active, affirmative consent. Pre-ticked boxes are non-compliant.
3. Selling Review Data to Third Parties Using customer review data for marketing without explicit consent violates both frameworks.
4. No Data Retention Policy Keeping review data indefinitely increases breach risk and violates storage limitation principles.
5. Ignoring Data Subject Rights EU customers have rights to access, correct, and delete their data. Ignoring requests creates legal exposure.
Privacy regulations continue evolving. Australia's government has signalled potential updates to the Privacy Act, likely bringing it closer to GDPR standards. Staying compliant now positions your business ahead of future changes.
Key takeaways for Australian businesses:
Compliance isn't a one-time project—it's an ongoing commitment. By treating customer review data with appropriate care, you protect both your customers and your business reputation.
Yes. GDPR applies to any Australian business processing personal data from EU residents, regardless of location. If you collect reviews from international customers, including those in Europe, you must comply with GDPR regulations. Non-compliance can result in significant fines and reputational damage.
Personal data in reviews includes names, emails, IP addresses, device identifiers, location data, purchase history, profile information, timestamps, and browsing behaviour. Even anonymised reviews count as personal data if individuals remain identifiable through context or metadata.
APPs govern how organisations collect, use, disclose, and store customer review data. Key principles include transparency about data collection, obtaining consent, limiting use to stated purposes, and implementing security measures. Compliance is mandatory for all Australian businesses handling personal information.
The Privacy Act 1988 allows penalties up to AUD $2.5 million for serious breaches. GDPR violations can result in fines up to €20 million or 4% of global turnover. Beyond financial penalties, non-compliance damages customer trust and business reputation.
Yes. Under Australian Privacy Principles, you must obtain informed consent before collecting personal data through reviews. Consent should be clear, specific, and easy to withdraw. Transparency about how data will be used, stored, and protected is essential for compliance.
Implement strong security measures including encryption, access controls, regular backups, and secure servers. Limit data access to authorised personnel only. Establish data retention policies and delete reviews when no longer needed. Both Privacy Act and GDPR require reasonable security safeguards.
Only with explicit consent. You must clearly inform customers their data may be published in reviews. Provide options to remain anonymous or use pseudonyms. Always respect customer privacy preferences and remove identifying information if requested, complying with both Australian and EU privacy standards.
