Scam caller claiming to be from Telstra technical support, informing me that my home internet had been compromised. Call started as a recorded message asking you to press 1, then the scammer joined the call.

Caller: Automated Internet Provider Scam

An Automated Scam Message System that says "A security has been breached which may cause disconnection of your internet line within 24 hours press 1 to speak to technical support"

I called back the number 0427 057 315 but the call didn't go through

Rang and didn’t leave a message.
When called back caller hangs up
Location comes up as Australia
Scam call?
