boong,
I do alot of solo hunting in the conditions you speak, i have a GME MT310 Epirb. Also the emergency number for your phone, if out of signal is 112.
Yes the snakes are out now too, i seen my first over the weekend, a little brown. It also pays to have an outdoor first aid kit, you can get them from your local chemist. Maybe even throw a rope noose in just incase of a snake. Even if you are hunting with companions, these simple & lightweight tools can come in handy.
