Meet 12 dangerous
snakes that all call
Queensland home.
Queensland has 88 land snakes, and some
of them are considered capable of killing
humans.
One of them – the western taipan – carries
the reputation of having the most toxic
venom of any land snake in the world. But
never fear, the western or inland taipan is
only found in a pocket away from humans
near the Qld-SA border and is not known
to have killed anyone. In fact, the eastern
brown snake – found all over the state
– is responsible for the most bites. But the
coastal taipan – with the longest fangs of
any Australian snake and a reputation for
multiple, efficient strikes – is the most likely
to exact a lethal hit. As summer approaches,
expect to find more snakes lurking around
your home, bush and farmland.
But remember, if you leave snakes
alone, they won’t want to hurt you.
