Diamond Python
The Diamond Python (Morelia spilota spilota) is Sydney's signature snake — a large, beautiful, non-venomous native python found nowhere else in the world outside of New South Wales and eastern Victoria. They are present across all five distribution zones of the Greater Sydney region, and they have adapted to suburban life better than almost any other large native reptile. Calm, charismatic and genuinely beneficial, they are one of the species that makes Sydney's wildlife distinctive. If you find one in your garden or your roof, the best response is calm appreciation rather than panic — and if you genuinely need it moved, a licensed reptile catcher can do it without harm to you, the snake or anyone else.
Blackish Blind Snake
The Blackish Blind Snake (Anilios nigrescens) is one of Sydney's most common but least visible native snakes. They live almost entirely underground, feeding on ant and termite brood, and only surface when heavy rain or disturbance forces them up. They are completely harmless to humans and pets, beneficial in the garden, and easily confused with worms or with juvenile venomous snakes. If you find one, the right response is to identify it carefully, move it to safety if it is exposed, and otherwise let it go about its quiet underground life.
