Red-bellied black snakes are one of the most common venomous species in Australia but have not caused any human deaths on record. The five adult and 97 baby snakes are currently under quarantine and will be released into a national park once the weather cools.

Pregnant red-bellied black snakes tend to pile on top of each other; two of the adults gave birth to 29 babies as they were being rounded up.

But one Sydney homeowner got more than he bargained for when a snake catcher unearthed 102 of the slithery reptiles hiding in his garden. David Stein had spotted a few snakes in a pile of mulch in his backyard in suburban Sydney and called Reptile Relocation Sydney to take a look.
