Lookout!

The giant Karri trees near Pemberton (likely to be over 250 years old) have been fire look outs for the last 80 years and provide a perfect vantage point from which to spot the first sign of smoke in this dense forest.
Amazingly in this nanny country of ours, we were still allowed to climb these, with gaps between the pegs easily big enough for a child to fall 100s of feet to their death.
We climbed all 3 of them 75mts (the Dave Evans Bicentennial tree), 65mts (the oldest Gloucester tree), and 56mts (the Diamond tree) and even the kids survived.
Luckily our most serious injury was still muscles.
