Hi Janton - most of our snakes are non -venomous. We do have a few venomous but very rarely see them unless you are somewhere in the bush. I think Australia has the most creepy crawlies.
These are our most dangerous snakes
Adders/vipers (puff adder, Gaboon viper, night adder and berg adder)
Mambas (black mamba, green mamba)
Cobras (Cape cobra, Mozambique spitting cobra, snouted cobra, forest cobra)
Rinkhals, boomslang and twig/vine snakes
