The odds of dying from a snake-bite in Australia is pretty low, with exception for very remote areas. most likely outcome is he will go to hospital instead of choose to die. If he does die, I'm sure he'll be discovered well and truly before the snakes die and all will be well or they will be destroyed as they may assume wild caught. Moving may just be a coincidence, but i am always suspicious of coincidence. These two people most likely haven't got any way of getting into contact with each other unfortunately, unless they already know one another or someone is willing to say they know both those people (which at this point in time would be a very risky thing to do and may lead to problems for that person.. so i don't see anyone putting their hand up for it) As someone else said "very sad day for the hobby"
