With their habitat gone, eastern brown snakes are expected to move into more populated areas as they search for food and shelter.Snake catcher Tony Harrison said eastern brown snakes were the second-most venomous land-based snake on earth.hey are definitely a snake that has a short fuse and definitely a snake you don’t want to get bitten by,” Mr Harrison said.”If there’s no refuge they feel threatened by … the birds of prey and whatnot … so they will desperately be looking for new places to go.”Eastern brown snakes avoid bushfires by slipping into rat holes at the base of trees, which become a bed and breakfast of sorts.The snakes go down here and can find refuge no worries,” Mr Harrison said.the resident python population and an imported boa constrictor, which was accidentally dumped at The Spit in April, were less likely to have survived because they move slower.That’s the first thing I thought of when I saw the smoke and heard it was at The Spit. I thought any pythons, including that boa, it’s all over,” Mr Harrison said.With the reptiles heading south towards the populated areas at Main Beach, people are urged to be alert but not alarmed, as snakes are happy to avoid human contact at every opportunity.
