The coloured sand sat in classroom craft cupboards for years. Teachers poured it into sensory trays. Children pressed it into bottles, crushed it between their fingers and carried it home on their clothes. Then laboratory testing found tremolite and chrysotile asbestos in the product. Australia banned all forms of asbestos in 2003. Even so, the material entered classrooms through imported craft supplies that no one thought to question.
A Recall That Kept Growing
The Australian Competition and Consumer Commission (ACCC) issued nationwide recalls covering brands including Kadink Sand, Educational Colours Rainbow Sand and Creatistics Coloured Sand. The scale surprised regulators. At least 22 sand products were recalled between November 2025 and May 2026, sold between 2020 and 2025 at major retailers including Officeworks, Woolworths, Kmart and Target.
The disruption to education was immediate. More than 450 schools in Australia closed temporarily after asbestos was detected in the imported sand. Classrooms became testing sites. Cleanup crews replaced craft sessions. Moreover, the problem extends well beyond Australia. Over 80 asbestos-tainted children’s sand products have been recalled across eight countries since November 2025, including New Zealand, the UK, France, Germany, Ireland, Malta and Canada. This is a global supply chain failure, traced back to contaminated source material.
The Research That Changed the Risk Assessment
Early official advice suggested the sand posed a low risk under normal, gentle play. Crushing, pulverising or heavy mechanical handling was flagged as the danger. That framing offered some comfort to schools and parents. That initial reassurance did not hold. A study from Auckland University of Technology found that 90 percent of craft sand samples released asbestos into the air during play.
The lead researcher stated the team had hoped to prove the products were safe. The findings showed otherwise. This matters for how educators think about exposure. Sensory play involves exactly the kinds of handling that release fibres. Children pour, sift, crush and blow on sand as a matter of course. As a result, the distinction between gentle play and mechanical manipulation breaks down in a real classroom.
Why Children Carry the Highest Risk
Asbestos harms anyone who inhales it. Children, however, face a sharper version of that risk, and this is commonly underestimated. Their physiology works against them. Children breathe more air per kilogram of body weight than adults, their airways are smaller and their lungs are still developing. Consequently, they inhale more fibres relative to their size from the same contaminated environment. Their biology compounds the problem. Rapidly dividing cells in growing tissue are more susceptible to carcinogens. Research estimates children are five times as likely as adults to develop mesothelioma from equivalent exposure. Four out of six studies reviewed found higher mesothelioma risk among people exposed in childhood compared with adulthood.
Behaviour adds a third exposure pathway. Young children put fingers and objects in their mouths constantly, which raises ingestion concerns when microscopic fibres settle on nearby surfaces. The timeline makes this a slow-motion crisis. Asbestos disease carries a latency period of 20 to 50 years. A child exposed today shows no symptoms tomorrow, next year or the following decade. The consequence arrives in midlife.
What Schools and Families Must Do Now
The immediate response is straightforward. Anyone holding recalled coloured sand should take three steps without delay. First, stop using the product. Check brand names against the ACCC recall list and remove any affected sand from play areas immediately. Second, dispose of it safely. Seal contaminated sand in heavy-duty, double-taped plastic bags. Then contact the local council for hazardous waste guidance, since asbestos materials require specialised handling.
Third, clean wet and never dry. Vacuuming or dry-sweeping suspected asbestos dust pushes fibres into the air. Wet wiping of hard surfaces contains and removes settled particles instead. Schools should also document which rooms held the sand and when. Those records will matter for any future health monitoring of staff and students.
The Questions That Remain
This episode exposes a serious gap in how Australia screens imported products for children. A material banned for more than two decades reached hundreds of schools through ordinary procurement channels. Moreover, testing caught the problem years after the products went on sale. As a result, policymakers face pressure to strengthen import testing protocols for children’s products and to fund independent verification rather than relying on supplier declarations.
School leaders face a parallel duty to build product safety checks into procurement, treating craft supplies with the same scrutiny applied to building materials. The affected children also need long-term attention. Given the decades-long latency of asbestos disease, health authorities must establish exposure registers now, while records of which schools used which products still exist. The sand has left the classrooms. The accountability work has barely started.
