He's wrong. You don't need to use the internet to talk to someone from Australia. Using HF radio you can talk all over the world just using the Earth's ionosphere.

Or V/U/SHF - there's this big, passive repeater in the sky known as the Moon.

Anyone having the Moon over their horizon at the same time as Australia does should have a fair shot at working an Aussie at 144MHz and above.
