Some walkie-talkies illegal in Australia

摘要

I've been seeing a lot of pop-up ads on Facebook for "Heider" brand PMR two-way radios which operate on 446MHz. They're quite small and reasonably cheap. And they have said that you don't need a licence to use them in Australia. I'd like to buy some for when we go hiking (they claim 15km range) but I am confused-someone has commented on Facebook that these are illegal to use in Australia. (R. P., via email)
