nearly all Australian snakes (apart from pythons) have highly lethal venom but they have short teeth so gaiters and boots and similar should be highly protective if you fail to see a snake and get too close to it and it tries to defend itself by biting you

when hiking be prepared for a snake bite

take first aid - bandages to create a mildly compressive bandage to slow lymphatic spread of venom (NOT that tight that it cuts off your circulation!)

if going where few other people will be and there is no mobile phone access, take gaiters as extra precaution and a communication device such as a personal radio beacon - especially important if you don't have a companion to go and get help for you

understand that you need to remain inactive to reduce lymphatic circulation speed and get to medical help as soon as possible - mostly you have a few hours if first aid has been applied - deaths within minutes is rare but can happen - and most snakebites are NOT dangerous as snakes generally choose NOT to envenomate you - so don't panic!
