Sea Snakes are highly venomous (they are a type of Elapid) - however bites are rare! bites should be treated the same as Australian terrestrial Elapids (constrictive bandage)
Mud Snakes
Mud Snakes are rear fanged and venomous but unlikely to cause serious envenomation
Colubrids
Some Colubrids are venomous, but very few species of Colubrids in the world are considered dangerously venomous.
