I was going to write a long reply on getting lost in the aussie bush but after some consideration I came up with few statements that I think covers my thoughts on this case:

1. He was dangerously under-prepared for the activity.
2. He made a number of mistakes that contributed to rescuers not finding him.
3. He is a very, very lucky person to have survived so long.

Unfortunately cases like this are soon forgotten which results in people continuing to make these types of mistakes and some pay the ultimate price while others manage to make it out alive.

Regards,
Michael.
