The worst thing about travelling throughout Australia is the lack of network communication in many areas. Telstra says they have 97% coverage- although I believe that refers to metropolitan areas not way out in the bush. Optus also has a similar coverage. Even Dodo has a bit of coverage although many places it does not matter who you are with – there is no coverage at all.
The problem is not having a lack of coverage to talk to friends on Facebook or similar, it is because you or a family member may have an emergency. While away I had this problem, one of my relations needed a critical operation and they could not contact me.
I was so surprised and pleased while travelling through the Pilbara to find free Wi-Fi coverage at a free campsite. That Shire has used there head and initiative setting up coverage at many free camping sites. If they can do it, why can’t the other networks and Shires do their bit.
