A signal that never reaches the hub is just a button on a piece of plastic.
In the remote regions of Australia and New Zealand, “trying to send” an alert is not the same as receiving help. Under the WHS Act 2011 in Australia and the HSWA 2015 in New Zealand, failing to provide effective communication in these zones is a critical failure of your duty of care.
Effective Communication Is a Legal Mandate, Not an Option
In New Zealand, the HSWA clearly states that a PCBU must provide “effective works of communication.” For Australian PCBUs under the WHS Act 2011, this means managing the risks of remote work with systems that actually function when cellular coverage ends, not just having a policy on paper.
The Danger of Relying on Recreational Beacons and Apps
We consistently see organisations treating Personal Locator Beacons (PLBs) or mobile phone apps as lone worker solutions. PLBs are emergency beacons only—they offer no check-in capability, no No-Motion Alerts, and no two-way communication, while mobile phone apps are useless the moment a worker leaves cellular range.
Reliability Requires Forwarding Technology and Confirmation
In our experience, Iridium is the only satellite network you should rely on because its 67 satellites use forwarding technology to ensure an SOS reaches an earth station even if the receiving satellite cannot see one. Genuine protection requires two-way communication and a confirmation to the user that the alert has been received, ensuring the worker has peace of mind that help is on the way.
Guardian Angel Safety: Turning Policy Into Real Protection
For over 12 years, we have helped Australian and New Zealand organisations convert their safety obligations into working infrastructure. By combining satellite-connected devices with 24/7 professional monitoring, we ensure that no worker is ever truly alone, regardless of how far they are from the nearest tower.
