- Try to not get in their way
Generally, snakes would not attack a human unless cornered. So if you spot a snake on your path, try to go around it if it's possible.
Unfortunately snakes love to sun bake, and that means that on a warm day in a bushland with known snake presence, there is a good chance you will spot one on a human trail because that's one of the places where they can get the most sunlight.
Personally, I have run into 3 snakes in one day while hiking the Great Ocean Walk, they all slithered away from me.
- Getting out of their territory
I have heard stories from fellow bushwalkers/hikers about how they were stalked by snakes. I can't verify those stories because I was not there. But some species of snakes are more aggressive than the others and in breeding season they might become territorial.
If you see many snakes in an area, i.e. near a creek, common sense should tell you to not go near where those snakes are.
And if you are already in the snake's territory, get out of it.
- Prevention is better than cure
If you go into total wildness with no mobile reception, it's best to bring a BLP (personal locating beacon) with the group. In snake infested areas, wear thick enclosed shoes, ideally with high ankle support or with gaiters. Making loud noises, so snakes know to get away from your path.
Remember, you are not on snakes food menu and they are afraid of you just like you are afraid of them. So if you give them space, they will leave you alone too.
