Great news this morning! Last night just before 8 pm we got a call from AMSA and were quickly able to find the tracking information for this flight, which ended in what looked like a normal approach to a sandbar. Unfortunately, the landing didn't go as planned and the two men managed to get themselves out and on to the beach but without being able to reach their PLB. When the SAR team was re-tasked to the coordinates we supplied, they quickly located the critically injured survivors, after 36 hours on the beach.
It goes to show the value of having a SIM in your iPad; Just $50/year prepaid from Telstra could save your life one day!
