hi Wingnut, as far as I know there are three types on snakes indigenous to the area, the brown and cream/yellow one is a viper and is venomous (straight to hospital) It has a sort of 'flat' head. There is also a black (on top)and white/cream belly, not sure about this one but the local farmers do kill it. There is also a pure dark grey/black one which, I believe, is a rat snake. Can't do you much harm but I would still avoid . Hope this helps
