A quiet morning turned chaotic across North Queensland when a leaking package triggered a major emergency response and left five postal workers hospitalised.
What began as a routine shift at two Australia Post facilities quickly spiralled into a full-scale hazmat operation spanning more than 130 kilometres.
Authorities now face the daunting task of uncovering what dangerous substance slipped through the nation’s postal network.
A worker at Australia Post’s Morris Street facility in West End, Townsville, first discovered the leaking package around 6:30 am.
After handling the item, the worker began feeling unwell, prompting an immediate evacuation and a rapid response from hazmat specialists.
Emergency services secured the site as paramedics treated the worker before taking them to hospital in stable condition.
But within minutes, the crisis spread.
The same package—already loaded onto a truck bound for Charters Towers—caused four more workers to fall ill at the Gill Street sorting centre around 6:40 am.
The back-to-back incidents revealed how the item had already moved through the mail system before its hazardous nature was detected.
Four Queensland Fire and Rescue scientific units were deployed to handle the unfolding situation.
These specialist teams are trained to manage chemical and biological threats, ensuring both facilities were properly contained and assessed.

Mail operations across North Queensland have been disrupted as investigations continue at both sites.
Charters Towers, located 136 kilometres south-west of Townsville along the Flinders Highway, serves as a key hub for postal routes connecting remote communities.
While authorities have not yet declared an exclusion zone, emergency personnel remain on scene as a precaution.
Residents in affected areas are being advised to expect mail delays while safety assessments are completed.
The scale of the response—from paramedics to hazmat teams—underscores the seriousness of the threat and the efficiency of Queensland’s emergency coordination.
Australia Post workers undergo regular training to detect suspicious items, but this incident highlights how even experienced teams can encounter dangerous substances that evade initial screening.
The rapid spread from Townsville to Charters Towers shows just how swiftly such materials can move through the postal network.
Immediate evacuation protocols are crucial in these situations, allowing hazmat experts to safely analyse and contain potential contaminants.

Authorities are urging senders to follow strict postal safety guidelines and never attempt to mail prohibited or hazardous items.
While the source of the leaking package remains under investigation, officials say the quick action of the first Townsville worker likely prevented a far more serious outcome.
The wellbeing of the five affected workers remains the top priority as all continue to recover in hospital.
Police, ambulance, and fire services maintained a strong presence at both sites throughout the morning, coordinating efforts to secure the facilities and identify the substance involved.
The response has been praised as a strong example of North Queensland’s readiness to manage complex and high-risk emergencies.
