The two most significant species encountered are Dugites and Tiger Snakes, both dangerously venomous and capable of a fatal bite.
Dugites are by far the more common of the two to be encountered, accounting for around 95% of snakes we remove and relocate.
Tiger Snakes are the second most common, but as a wetland species, most people will only encounter them if they live within a street or two of a wetland known for having them — or occasionally when one has been accidentally transported in building materials.
