   Initial investigation indicates an alarm, likely caused by a potential inland fibre break between Adelaide and Perth. Field teams have been dispatched to site and are currently en-route, to conduct further testing and isolation.

   Field engineers have conducted OTDR testing and located the issue at a construction site. They have begun excavating the pit to isolate the fibre. Due to the complex nature of the break and extreme weather conditions, there is a delay in the isolation process.

   Engineers have investigated further and found that the break occurred due to a pipe being installed by local contractors near the railway corridor, resulting in a fibre cut underground. Civil excavation will begin soon to expose and repair the damaged fibre.

5. identified Jun 06, 2025, 09:09 PM UTC

   Excavation work has uncovered the damaged section of cabling at a depth of 3.5 metres. Inclement weather continues to be a factor during remediation works. We expect to progress to the fibre cable replacement phase shortly after which splicing activities will commence. Due to the ongoing complex nature of this repair we are not able to provide an ETR at this stage.

   Fibre repair team advised services should start restoring in the next 45 min and final ETR is 19:30 local Adelaide time.
