I was with the park manager in Limbang when he got the call about this.
A 26 year old Australian stayed for a couple of nights with Tim Kalang near the Mulu clinic. He went into the park and texted Tim to say he would stay there overnight. The story I heard a couple of days ago was that he then went to Sarawak Chamber on his own and without a guide. My guess then was that the river flooded after heavy rain and he got stuck in there and probably ran out of light.
Not sure why it took more than a week to report him missing. I heard that the local people spent a couple of days looking for him before they raised the alarm.
I understand he previously went to Mt Kinabalu against the rules, without a guide and also Baku National Park.
It took three days to find him with over 30 people searching.
Maggots in the leg is good, it helps to prevent gangrene! I think they may have migrated from his brain - pillock!
However news since then suggests he was found in Hidden Valley or Camp 1.

I guess I won't know the truth till I go to Mulu in December.
