Tiger snakes are among the most lethal of venomous Australian snakes. They are second only to brown snakes in terms of causing fatalities. It used to be the top killer, but their numbers declined due to decreasing prey (mainly frog) populations. Snakes could get close to residential areas to take advantage of water and prey (rodents) that come with human habitation.
Tiger Snake Bites
People get bitten by a tiger snake when they have trodden on it, poked into its hiding places, or when they are deliberately handling the snake or trying to harm it. From the point of view of the snake, these are perceived as a threat, and to bite is a defensive action.
