Hallett Cove has many open spaces with playgrounds and natural (annual) creek lines, council parks, the Conservation Park, and open paddocks. This environment lends itself to many types of fauna, including snakes and lizards. Their presence is mainly seasonal. I have never seen any snakes in the streets or in my garden, however I have seen them in the Hallett Cove Conservation Park. Blue Tongue Lizards are more prevalent, though usually harmless.
