AustraliaA defective bicycle helmet failed in an accident. Can I claim against the seller?
Yes, you may claim against the seller under the Australian Consumer Law if the helmet was unsafe, failed to meet consumer guarantees, or had a manufacturing or design defect.
What the Law Says
The Australian Consumer Law (ACL) provides strong protections for consumers who buy goods like bicycle helmets. If a helmet is defective and causes injury, the seller — and often the manufacturer — may be held legally responsible.
Under the ACL, every sale of goods includes automatic consumer guarantees. One key guarantee is that goods must be of acceptable quality — meaning they are safe, durable, and free from defects. A helmet that fails during normal use likely breaches this guarantee.
The ACL also prohibits 'unsafe goods'. A bicycle helmet that does not comply with the mandatory safety standard (AS/NZS 2063) is considered unsafe. Sellers must not supply such goods.
You do not need to prove negligence or fault — liability under the ACL is strict. If the helmet was defective and caused harm, the seller may be liable for compensation, including medical costs, lost wages, and pain and suffering.

What to Do
Keep the defective helmet, packaging, receipt, and any photos or medical reports.
Contact the seller in writing to request a repair, replacement, or compensation — citing the ACL.
If unresolved, lodge a complaint with your state’s consumer affairs agency (e.g., NSW Fair Trading or ACCC).
Consider seeking legal advice — especially if injuries are serious — as claims can be made in state tribunals (e.g., NCAT, VCAT) or courts.
Act within 6 years of the incident — the general limitation period for ACL claims in Australia.
