Perth Airport

The airport CallTech built Active Response for. One trigger sends every response team member an SMS at once, calls anyone who does not respond, and logs who acknowledged - used for every airside, landside and site emergency.

Perth Airport needed key staff and emergency agencies notified in seconds, with proof of who had received the message. CallTech built the system that does it - and it became a product.

Perth Airport handled a record 18 million passengers in 2025 and runs 24 hours a day, seven days a week. It cannot afford disruption, so when an incident happens, key staff and emergency agencies have to know within seconds.

The Issue

Aviation incidents involve a wide range of people: airport staff, emergency services, government agencies and other stakeholders. Before PARS, the contact list lived in an Excel spreadsheet and staff rang each person by hand. That was too slow, and it gave no record of who had actually received the message. Perth Airport needed a call-out system that reached everyone at once and reported back who had responded.

The Solution

CallTech designed and built the Perth Airport Response System (PARS), which has since become CallTech’s Active Response product.

When an incident is raised, Active Response sends an SMS with the incident details to every member of the response team at the same time. Anyone who has not responded within two minutes is called. Recipients acknowledge and register their availability through simple text or voice prompts, so the airport knows within minutes who is available.

Every notification and response is logged. The incident reports are used for staff training and to improve the response to the next event.

When PARS went live in 2003, the time to assemble an emergency response team fell from about 30 minutes to under 3. Perth Airport has relied on it for every emergency since, whether aviation, airside, landside or elsewhere on the estate. Emirates runs the same system today, and Sydney Airport ran it for a number of years.

The system is efficient and enables fast and effective communication during incident responses.

The result

Assembling an emergency response team went from about 30 minutes to under 3, and Active Response is now used for every emergency across the airport estate. Emirates runs the same system today, and Sydney Airport ran it for a number of years.
