I extremely amazed her mobile phone worked in the bush. Australia is a big country and outside of urban areas and other than along some major highways there is NO coverage. Probably less than 10% of the continent (no sure what Telstra says at the moment).

Relying of being saved by a mobile phone call is extremely foolish and I think she can't have been that far into the bush to get a call through (don't know that area).

The "best" story I ever heard was of a Japanese motobike rider who set off along the "Gun barrel Highway" with no other drink than a single can of Coke. When his motorbike broke down he sadly died and was actually within a hundred metres of a stock water bore (which had water in it). He was too stupid to drink the bore water. Guess it had to come out of a bottle or can to be drinkable
