Many people replace old phones, laptops, or tablets without realizing the sensitive information is still on them. Cybersecurity experts have even found that major companies and agencies discarded completely unwiped devices. With researchers stating there were instances of discovering state government network encryption keys and full medical records on second-hand hardware. They also found spreadsheets with customer names, addresses, phone numbers, and credit card details. These are just a few examples of the real risks of not destroying data on old equipment.
Such incidents show that old devices can spark a data breach even after they are thrown away or recycled. If leftover data from a discarded drive or phone is accessed by a third party, the original owner has effectively lost that information. Under Australia’s Privacy Act, loss or unauthorized access of personal data is treated as a notifiable data breach. This means a simple failure to wipe an old hard drive can trigger an official breach report, with legal consequences.
In Australia alone, businesses generate hundreds of thousands of tonnes of electronic waste each year, and only a fraction is collected securely. Any unwiped device in that waste stream can be a goldmine for data thieves or hackers.
Australian Laws and Penalties for Data Disposal
Australian law places clear responsibilities on organisations and, by extension, individuals in business to manage and dispose of personal data securely. The Privacy Act 1988 (Cth) and the Australian Privacy Principles (APPs) within it set the rules.
Importantly, APP 11 (Security) requires entities to “take reasonable steps to protect the personal information they hold from misuse, interference, and loss.” APP 11.2 goes further, mandating that businesses must “take reasonable steps to destroy or de-identify personal information once it is no longer needed.”
In other words, you can’t simply stash away or toss old devices with personal data, and you must ensure the data is irrecoverably erased.
If an organization fails to do this and a breach occurs, the Notifiable Data Breaches scheme kicks in. Under the Privacy Act’s NDB rules, companies must notify both the Privacy Commissioner and affected individuals when an eligible data breach happens. Such an incident qualifies as a reportable breach when personal information has been disclosed in a way that creates a substantial risk of serious harm. Which pretty much means if someone retrieves personal info from your discarded hardware, you have a legal obligation to report it. The goal is to allow affected people to take steps and hold businesses accountable.

If you don’t stick to these rules, it could end up costing you a fortune. In late 2022, Australia overhauled its penalties, and now serious or repeated privacy breaches can attract the greater of a $50 million fine, three times the value of any benefit obtained from the breach, or 30% of the company’s turnover. For small businesses, the old caps were set at $340,000 for individuals and $1.7M for organizations, which were already high by their standards, but the new regime reflects how seriously regulators treat privacy lapses. Meaning a data breach caused by a discarded device is treated the same as one from a live database and could lead to fines in the millions.
Consequences of Improper Data Disposal
Regulatory Fines
Under the Privacy Act, a data breach caused by negligence, such as failing to wipe a device, can attract huge civil penalties. The 2022 reforms mean a company could face tens of millions of dollars in fines. Even before these changes, Australian regulators were beginning to act. In 2023, the OAIC sued a pathology provider for a breach, seeking penalties under the old law.
Breach Notifications
You need to let both your customers and the regulator know anytime personal information is exposed, no matter how it happens. Imagine you sell an old phone without wiping the client data, and that information leaks. That’s a notifiable breach under the Act, and if you don’t report it, you are breaching the law.
Civil Liability and Lawsuits
Customers or employees whose data was leaked might sue for damages, arguing your business was negligent in protecting their privacy. While Australia has had fewer privacy class-action cases than some countries, companies abroad have paid dearly for such failures. In 2022, a major US bank paid a $35M SEC penalty after hiring a moving company to decommission old drives, and the drives were sold with customer data still intact.
Reputational Damage
Public trust can crumble after a breach such as this. Research shows many people lose confidence in a company after their data is compromised. News of a data breach from an old device will likely damage your brand and customer loyalty as much as, or more than, any fine.
Targeted Attacks
Cybercriminals regularly mine secondhand electronics looking for sensitive data. An unsecured hard drive or phone is an easy entry point. Studies have shown that identity thieves recover vast amounts of personal data this way. Any resulting identity theft, fraud, or cyberattack can turn into legal and financial liability for the original data holder.
How to Securely Destroy Data on Old Devices
Backup Needed Data
Before disposing of anything, make sure any required information is safely backed up or transferred.
Thoroughly Erase or Wipe Data
Don’t rely on simple delete or reformat. Use reputable data-wiping software or built-in secure erase functions that overwrite the entire drive multiple times. Methods meeting standards like NIST SP 800-88 should be used so that data cannot be recovered by ordinary forensic tools.
Physically Destroy Irreversible Media
When you are sure a device be used again by you or anyone else, the surest way to get rid of any data is to physically destory its storage. Drill through hard drives, shred the disks, or degauss those old tapes, whatever it takes, to make absolutely sure nothing can ever be recovered.
Use Certified Recycling/Disposal Vendors
When sending devices for recycling or disposal, choose vendors with recognized certification and secure chain-of-custody. They should provide a “Certificate of Destruction” as proof that the media were erased or destroyed. Merely dropping a device in the bin or a general recycling stream is not secure. Australian government guidelines explicitly warn against disposing of information-containing devices as regular trash and never leaving information at the local tip, as it may be retrieved.
Documents and Policies
Keep records of what data was destroyed, when, and how. For businesses, having a formal data destruction policy is important. It should assign responsibility, detail approved methods such as software wiping, shredding, etc., and require periodic audits. A well-documented process shows you took reasonable steps to comply with APP 11, which is crucial if there’s ever a dispute.
Train Employees
Make sure your staff understand the importance of data disposal, as human error is often the leading cause of data breaches. Regular training can prevent someone from casually tossing an old laptop without authorizing a secure wipe.
Takeaways
Destroy vs Delete
Keep in mind, just hitting “delete” or reformatting won’t cut it as data recovery tools can pull your files back in no time. To be safe, you need to either physically destroy the storage or use a certified wiping method to make sure nothing can be retrieved.
Legal Responsibility
Under Australian law, you are responsible for the data, even on discarded devices. If you don’t erase data correctly, you could be violating privacy laws and end up with fines and required breach notifications. The legal consequences of improper data disposal can include expensive civil penalties, not to mention potential lawsuits by affected individuals.
Global Standards
These concerns aren’t unique to Australia. International regulations mirror these requirements. The EU’s GDPR requires data controllers to implement adequate security, which includes secure deletion of personal data. GDPR violations for insecure data handling can bring fines up to €20 million or 4% of global turnover. In the US, laws like HIPAA for health data and FTC guidelines also mandate the secure disposal of records.
Environmental and Ethical Concern
Proper disposal is also environmentally responsible. Many organizations that mishandle e-waste may be violating environmental regulations too, but critically, they definitely risk data theft. Always treat old electronic media as potentially containing sensitive information.
In summary, not properly destroying data on old devices is a hidden but serious vulnerability. The data destruction legal risks are real, and data breaches can happen long after a device is discarded. Businesses can face heavy fines, mandatory breach reporting, and lawsuits as a result. To protect yourself and others, always use certified methods to erase or destroy data, as it’s a simple insurance against huge legal and reputational costs.
