I've elaborated on grahams post.
Trust Your bandage - don't stuff around trying to suck out venom.
1. Don't clean the wound
This is because we have very good methods of snake identifcation from the venom/saliva let on the skin.
2. Apply Pressure bandage
Venom of Australian snake s also travels via the lymph glands. That is why a pressure bandage is preferble to a tournque.

3. Seek Medical assistance/Hospital immediately
Surprisingly this doesn't always happen

4. Allow a swab of the bite area (without removing the bandage)
In other words, don't say to the doctor "No, you can't take a swab (sorry - couldn't resist
5. Don't remove bandage until a doctor is ready with the antivenine.
couple of others.
Always carry a first aid kit with extra crep bandages if you are a mad herper and travel to areas where you may see snakes. I carry 2 extra crep bandages.
Also always have a way out. I carry an EPRIB to scream for help if required. I already have the procedures mapped out if I am unlucky enough to need it.
