Do I legally need to wipe data before selling old computers or hard drives for scrap in Australia?
Short answer: There's no single blanket law forcing every individual to wipe a device before recycling it, but Australian Privacy Principles create real obligations for businesses handling personal information, and leaving data recoverable is a genuine security risk regardless of legal requirement. Reputable e-waste buyers offer certified data destruction, and for any device that held personal, financial, or business data, using it is strongly advisable rather than optional.

If you’re a business disposing of equipment that held customer or employee data, the Australian Privacy Principles under the Privacy Act generally require you to take reasonable steps to destroy or de-identify personal information you no longer need — simply deleting files or reformatting a drive doesn’t reliably achieve that, since data can often still be recovered.
The practical risk either way
Whether or not a specific law applies to your situation, a hard drive or SSD sold without proper wiping can have its data recovered by anyone with basic tools. For anyone who has ever used the device for banking, work files, or personal photos, that’s a real exposure worth avoiding regardless of legal obligation.
What proper destruction actually looks like
Certified data destruction typically means either secure software wiping to a recognised standard or physical destruction of the storage media, with a certificate of destruction provided as proof — ask any e-waste buyer handling drives whether they offer this and whether documentation is included.
