The basis for the following discussion and points of view are personal experience, comments heard and questions asked during my time lecturing on venomous animals as well as a perusal of the relevant literature. This is a misrepresentation of the facts and gains little support from the evidence available concerning humans. These types of statements have no place in education if positive results are the goal. All venomous snakes have the potential to be dangerous because of the variable sensitivity between individual people to venoms. However, first a bite has to occur.
Australian snakes are inoffensive and very shy.
They have had only forty thousand odd years of human predation to contend with. None of their behaviour has evolved targeting humans. Maybe this is why it is almost impossible to accidentally get bitten by one unless you run around the scrub in bare feet with your eyes shut, and half full on alcohol. On other continents humans have existed for hundreds of thousands of years. This behaviour would have little effect in deterring a predator looking for a feed, but it may deter a passing human from taking up a club and clobbering the snake into lifeless pulp.
