I was out picking Lemon Balm this afternoon and came across an Eastern Brown snake. Fortunately he went away from me, as I have found most snakes will when they can. The majority of people that get bitten do so when trying to catch or kill a snake, or because they trod on one. We used to get a lot of King Brown snakes in our house in the Territory, even found one in our child's cot when I went to lay him down one day!
NEVER step over a log or downed tree if you can't see what is on the other side. Mostly you won't be able to see the other side close to the tree. Go around the tree/log or step up on the log/tree and stop & look before your next step.
Mostly we get Eastern Brown snakes and Red Bellied Black snakes around here, but we did have a Tiger Snake kill one of our dogs some years ago. Mostly a snake will move away from you if it senses you are near, but if you are hunting or stalking and walking quietly, then you may get closer to a snake than you want to!
Learn to identify the snakes common to your area. Learn first aid. Always carry bandages when in the bush. Look where you are walking and sitting.
This video below is the best one I have come across so far.
