Sneaky little devil almost cut my serene weekend on Magnetic Island short. Death adders are famous for not getting out of your way (even though, compared to them, you are a big lumbering monster) and for having a rather nasty bite. Although it may not have killed me (the last recorded death due to a death adder in Queensland was an 11 year old girl in the 1930s (at least according to Wikipedia)), it would certainly have ruined my day.
In the end, I respectfully retracted my already extended foot, and bravely chose a different path through the undergrowth.
Thanks for chilling out on top of the warm rock, rather than being buried under some leaf litter, where I would probably not have spotted you.
