Compression bandage used for reducing transmission of venom in the body.
The US doesnt follow this as rigidly since they dont have as many deadly snakes and for several species compression is not advised as it can cause tissue destruction from the venom in that area.
Australia has more deadly snakes which also may not be identifiable by victims. As such the first aid priority is assume its deadly, apply compression and accept the chance of tissue destruction.
Yep,
The snakes in my area are all venomous. They are the eastern brown, red belly black, tiger, copperhead and death adder. There are non venomous pythons and various tree snakes but not in my local area. So we treat them all with respect. Nothing to be frightened of, just be careful and keep an eye out for them.
At least we don't have grizzly bears and have to carry a side arm when fishing. Or a bear stopping cartridge.
