Eastern Tiger Snake
The Eastern Tiger Snake is found in the southern regions of Australia, including coastal islands, such as Tasmania. They are highly venomous and should not be approached.
The average length for tiger snakes is around 1.2m, although they may reach up to 2.1m. In general, males may be larger than females.
Eastern Tiger Snakes are highly variable in colour; banded individuals are fairly distinct and unlikely to be confused with anything else, except perhaps a banded form of Eastern Brown Snake. Juveniles could be mistaken for the Rough-scaled Snake or the Stephen’s Banded Snake. Some Tiger snakes without a pattern may be mistaken for several other venomous snakes, e.g. Copperheads or Black Snakes.
