I've lived near the reserve for about 20 years and I haven't heard of anyone being bitten by a snake there (although some dogs have, unfortunately). I think accidents could happen but they'd be pretty rare. The snakes here tend to stick to the long grass and near the creek and I think most people have the sense to not go trampling through the grass during snake season.

It also depends on the snake species. Around here we mainly have Eastern browns, which are venomous but timid. In other places in Australia snakes may be more aggressive and accidents are more likely.

Logically, I know I have nothing to worry about, but my main character syndrome makes me worry about when it will eventually happen.
