It is also known as the king brown snake!

As per NatGeo, it is found throughout Australia, except in Victoria, Tasmania and the most southern parts of Western Australia – the widest distribution of any Australian snake

The mulga is the heaviest venomous snake in Australia and has the largest-recorded venom output of any in the world – delivering 150mg in one bite; the average tiger snake only produces 10-40mg when milked.

Their temperament seems to vary with locality. Southern mulgas are reported to be shy and quiet, whereas northern specimens are much more agitated if disturbed – when they throw their heads from side to side and hiss loudly.

Mulgas bite savagely, even hanging on and chewing as they inject massive amounts of highly toxic venom, which destroys blood cells and affects the muscles and nerves. Though commonly known as a king brown snake, the mulga is actually a member of the black snake genus Pseudechis, and black snake antivenom is needed to treat a bite.
