they do...we are talking corn snakes here arnt we! dont get me wrong,but lets put it in perspective...in the 1800s a ship captain tryed to establish red bellied black snakes(luckly it wasnt tasmainian tiger snakes)...thankfully it failed....as far as i know pythons have been smuggled to nz for at least 40 years...anyone seen one? what about sea snakes that wash up...how venomous are they!!!!dont get me wrong,the last thing i would want to see established is a snake,but more than likely it wouldnt be venomous as people arnt that stupid these days.and if it was it would more than likley be eaten by a cat,dog ,ferret,stoat,e.c.t :roll: stop the knee jerk reaction!!!! :roll:
