Most snakes shouldn't be a problem to the astronomy fraternity. In the main they will react to noise and vibration and seek quieter quarters out of the way of human danger. Death Adders can be a little different because of their liking to hide in a leafy location luring prey with their distinctive tail colour and movement. They are less prone to getting out of harm's way, and are likely to attack if stepped on. I believe their thinking is,
"you should have seen and recognised the distinctive tail, and gotten out of my way!" Not always possible at night, when both of us are going about our business. Anyway, what is an astronomer doing in a leafy location? If somebody, has a better knowledge of the Death Adder's habits, please feel free to correct me.
In the north, I am yet to encounter any reptiles while out viewing, but we have been accompanied by howling dingoes, and have to be most cautious about roaming water buffalo. The latter can be a very real problem. If near the water's edge, there's the crocs
, which could really ruin your night out if given the opportunity.
