`David Iredale did not behave in the way of most people when bushwalking in dense scrub.
Instead of sticking with his two mates, the 17-year-old, who has been lost for a week in the Blue Mountains, adopted a practice of walking ahead, leaving them to trek behind until he found a place to sit down and wait for them.
“He would go ahead and wait,” he said. “He was faster than the others. On this occasion he went ahead to fill up with water at the Kedumba River.
“When his companions got there, he was not there. They assumed he had gone ahead. Soon afterwards, David made the call on his mobile phone that he was lost.”‘
