A Queensland state school is closed following an incident in which students are allegedly linked to a chemical substance being brought onto campus. Multiple reports say authorities respond to the situation after concerns are raised about a possible toxic exposure at the school in south-west Queensland. The West Australian reports that the school is shut down after students allegedly bring mercury onto the premises, prompting an emergency response.

ABC Australia also reports that the closure follows a potential mercury exposure incident at a south-west Queensland state school. ABC states that authorities are investigating the circumstances, including whether mercury exposure occurred and the extent of any risk to students and staff.

Across the accounts, the focus remains on the investigation and safety response, with no confirmed details provided in the reports about how the mercury was handled, how much was involved, or the specific actions taken beyond the immediate emergency measures and the decision to close the campus. Further updates are expected as investigations continue.
