Guardian has been successfully deployed to proactively protect the highest risk section of EAC2 Cable.


  • Telstra has used AIS since 2013 to reduce unplanned subsea network impacts.
  • Cables in the Singapore Strait are particularly at risk with more than 2,500 vessels and 11 million metric tons of cargo movement every week.
  • Despite using manual monitoring and intervention, incidents still occur, resulting in damage to these cables.
  • Telstra sought a proactive solution to further improve their network resilience.


  • Guardian:protect marks Telstra’s EAC2 Cable with Virtual Aids to Navigation (VAtoN) that are visible on vessels’ navigation systems in real-time.
  • Guardian detects risky behaviour (eg anchoring) or high risk vessels (eg fishing trawlers) and sends a real-time message to the navigation system of that vessel.
  • The Guardian AIS Station was strategically located near the coastline to proactively protect the 75km of cable that had incurred multiple incidents.


  • Telstra’s goal is to further reduce incident rates in the high risk Asia Pacific region.
  • The highest risk section of EAC2 is now proactively protected.
  • Since the roll out of Guardian solution in Dec-19, as well as it’s integration into the existing AIS monitoring system, Telstra envisages improved network services with lesser disruptions and subsea repairs.
