Call made by a guy saying he was a Telstra technitian saying my iP needed to be switched from public to private as my contact details were exposed and could be accessed by anyone. I asked for Telstra´s number and he provided me with 1800 834 273 (which is a genuine number but has been spoofed and used by scammers in the past). I was busy and he would call me in 2 hours. He said for me not to do any internet banking or use my email during this time. I can smell a scam!
