Caller: Said they were Telstra

Said were from Telstra and they had detected that people were accessing my computer.
Wanted to sell me technical support to fix the problem.
I know enough to know this is a scam. When I questioned him he hung up.

Caller: FAKE Telstra

Tried to get tell me other people were connecting to my computer and tried the trick of getting me to type netstat (from there he would get me to allow him to take control of my computer!)
When I said I wasn't using Telstra he said "It doesn't matter, Telstra is the Mother of All Internet Connections and everyone else is just using them" HAHA
