Safety Alerts – Case Study

Sonder Safety Alerts during 2017 Flinders St attack

At Sonder, we monitor all major public safety incidents in Australia, and have the technology to help protect our members if something happens near them. When someone drove their car into a busy pedestrian area near Melbourne’s Flinders Street Station in 2017, we used our Safety Alerts function to ensure the safety of our members who were nearby at the time of the incident.

On the afternoon of December 21, 2017, a 32-year-old man rammed his car into a group of pedestrians outside Melbourne’s busy Flinders Street train station, killing one person and injuring 17 others. Nine of the victims were overseas nationals from countries including China, South Korea, India, Italy, Venezuela, Ireland and New Zealand.

At Sonder, we closely monitor all public safety incidents as they unfold, through our world-class operations facility. The Sonder Support Centre was able to quickly identify the Sonder members in the vicinity of the Flinders Street incident. Within three minutes of the incident being officially confirmed by the Victorian Police, Sonder initiated a Safety Alert asking the members to confirm their safety, followed up by a phone call.

Here’s what happened to one of our members who we located to be near Flinders Street Station that afternoon.

Chinese student’s ‘surprise’ phone call

In a restaurant close to Flinders Street Station, a 21-year-old female Chinese student, and Sonder member, was having lunch when the attack happened. Within minutes of the incident occurring, she received a text message alerting her something had happened and asking to confirm if she was safe. When there was no response from the student, the Sonder Support Team followed up with a phone call to check on her safety and to warn her to avoid the area. She hadn’t seen the original message and was not aware of the incident, so was extremely relieved to have had the follow-up call.

“I received a surprise phone call from Sonder when I was having lunch at Chinatown. It turned out to be that there was a major incident that happened in Melbourne CBD nearby so they were calling to make sure that I am safe. After the phone call, the thought that I could have left the restaurant and run into the incident if Sonder staff didn’t call me really made me worry.” – Student and Sonder member, 21, Melbourne

All potentially-affected members confirmed their safety and Sonder ensured they were kept informed about how to stay safe. These members included students at four surrounding educational institutions. In addition, all associated institutions were immediately informed of the safety status of their students.
