I've lived in taht very dangerous town, the epicentre of sheer terror that is Sydney for most of my 43 years and have never seen any of the deadly animals in the wild with the exception of the octopus which I saw once in a rock pool whilst visiting Gunamatta bay near Cronulla. I've been a keen hiker and camper for most of that time and have only seen 2 deadly snakes in all that time. Never been bitten by anything more ferocious than a mosquito and have never felt really in danger from the wildlife here.
As long as you take the proper precautions nothing is likely to make a meal of you:
