Received call from unrecognised number. Did not leave a voicemail. Phoned number - unavailable number

Missed call. No message left. Assume it’s a scam.

Called me, but I did not pick up as it was marked as spam. Left a voicemail; was a male with an Asian accent asking: "Can I speak with [my first name] [my last name]?" Don't know who they are or how they got a hold of those details.

Caller: Buy a number

Just another buy a number off the internet caller who never leaves a message. Blocked.

Did not leave message, got a call from a similar number, same first 4 digits but different last 4 digits. When I called back, the number was said to be not in use. Possibly scam with spoofed number.

Caller: I don’t know

Asked for me by name. I didn’t say it was me but I asked who was calling then they hung up.

Caller: Scammer saying they were Telstra

Received call from 'Telstra support' talking about my ISP being public not private, i dont have internet with Telstra and my i am not the primary on my telstra mobile account. Scam.

They called, didn’t leave a message. When I called back I got the engaged signal or no answer, with no voicemail. Probably scammer.

Received a call from this number, did not leave a voicemail. Likely a spam call.

recieved call, answered, no return answer

He said calling from.NBN, is this NBN?

Unknow to me and didn't leave a message so blocked number
