Mobile number 0485 855 484 called & hung up, called back and a foreign sounding lady asked for the owner, that she is ringing from Information Connect - Inactive Super Funds. I did an ABN lookup, no such business exists by this name.
I did not identify myself, said that Gov does not call people from mobile numbers, and that this call will be reported to TIO and ACCC. This is very likely a SPAM call / BLOCK. Report.

Caller: I don’t know

Called near lunchtime. Given prior comments I plan to block this number.

keeps calling but never leaves a message.

Caller: 0485 855 484

Claimed they were Telstra and they wanted to track my IP addresss. Asked if I knew how to change IP address have also said let them help you change it so you can’t get scammed
Hung up after they said open up google and I’ll check from where they were.
Tried to call number back after and was a foreign lady automatic message saying customer service and to press 1 2 or 3
