The geographical range of this species extends over almost every 
part of Australia, and the collection embraces specimens from Cape York, 
Adelaide, the Murray, and other localities. When full grown, this snake 
is dangerous to man; it is diurnal, and inhabits rocky localities ; young 
individuals are frequently found under stones during the cold season, 
while those of a more mature age retire into the ground.
