Three times in three days a ph call from "telstra" saying files from computer are corrupting their system. I need to go to my computer login using their given id and follow their instructions. I took one to the brink and then said I had a Mac and he hang up.
I told another one I had phone the telstra faults line and he then hung up. One today happily gave me this number.

Yep , Called with the same story. Even provided a ficticious employee ID number. Perhaps one of the more convincing scammers that have rang.
Give this one a big big flick and Telstra should really look into as there is a better than even chance that some older folk are likely to be caught.

another guy with an indian accent claiming to be from technical services at telstra.
again,another scam to get access to your computer
