Asbestos in Craft Sand Closes 450+ Schools in ANZ

More than 450 schools across Australia shut down temporarily in late 2025 after laboratory testing confirmed tremolite asbestos in popular colored craft sand used in classrooms. The contamination, traced to products imported from China, prompted the largest school-related asbestos response in recent Australian history.

In New Zealand, the crisis followed within days. By mid-November 2025, at least 150 schools and 90 early learning services had contacted the Ministry of Education after identifying recalled sand brands on their premises. The Australian and New Zealand school closures became the opening chapter of the global asbestos craft-sand recall pattern that has since spanned 12 countries and 80-plus product notices.

How the Contamination Was Discovered

Laboratory testing in Australia in late 2025 detected tremolite asbestos, a needle-shaped amphibole fiber considered more hazardous than the more common chrysotile form. The findings initially reached New Zealand authorities through a podcast, prompting rapid checks at schools nationwide.

The contaminated products include:

• Educational Colours Rainbow Sand (1.3 kg)
• Creatistics Coloured Sand (1 kg)
• Kadink Decorative Sand (10-gram six-pack and 1.3 kg)

These brands were sold through Kmart, Officeworks, and Woolworths, and had been in use in classrooms since at least 2020. The sand was used in art classes, sensory play, and craft projects. In some schools, spilled sand had been ground into classroom carpets over months or years.

School Closures and Cleanup

The scale of closures was significant. In Australia, 69 schools in Canberra alone fully shut for decontamination. More than 40 schools in Tasmania closed or partially closed. Across both countries, WorkSafe conducted inspections at more than 150 sites.

Cleanup required licensed asbestos removalists. Classrooms where sand had been spilled needed professional decontamination, including carpet removal in some cases. The cost per school averaged approximately $11,000.

Schools that had the sand in sealed, unused containers were cleared more quickly. Those where sand had been opened, used in projects, or spilled required more extensive remediation.

Health Risk Assessment

Health authorities in both countries emphasized that the risk from brief, low-level exposure is low. Tremolite asbestos is dangerous primarily through repeated inhalation over time. A child using contaminated sand in a single art class faces a different risk profile than a construction worker exposed daily for years.

That said, any asbestos exposure carries some degree of risk, and children face a longer lifetime in which disease could potentially develop. Mesothelioma has a latency period of 20 to 50 years between initial exposure and diagnosis. Health officials advised parents not to panic but to seek medical advice if they had specific concerns about repeated exposure.

No illnesses have been reported in connection with the contaminated products. Authorities recommended that parents and schools document any known exposure for future medical records, even if no symptoms are present.

Questions About Import Controls

Both Australia and New Zealand have comprehensive bans on asbestos. The contamination raised questions about how products containing a banned substance entered the market and reached children.

The sand was imported from China, where asbestos mining and use continue in some regions. Natural asbestos can occur in sand deposits, and without routine testing of imported raw materials, contaminated products can pass through customs and reach retail shelves.

Regulators in both countries have launched investigations into supply chain oversight. The Australian Competition and Consumer Commission (ACCC) issued product recalls, while New Zealand’s Ministry of Business, Innovation and Employment expanded testing to other imported sand products.
