Rang for a few seconds, no message left, unknown. Suspect spam. Have had many similar calls from other mobiles recently. I block and delete.

Caller: Spammer

Caller lets phone ring 4 times then hands up.
No message left.
Block number

Did recognize number, not in my phonebook no message left. Rang back and got " call failed & busy signal" suspect a scam. Blocked & deleted.

Caller: Some Butthole

Butthole called. I was already on another call
They left no message.
Blocked.

when it came up on my phone, it just says its from "australia" so clearly not a mate calling me. not going to answer that

Hung up when answered

Scammer I believe.

Answered, got radio silence so hung up. Number blocked

No one spoke when answered and hung up after 2 secs. Suspected scam

Same as other comments. Hung up when answered. Could hear noises like call centre in background. Called the number back from few different phones and each time said call couldn't be connected.
So obviously spam.

Calls and Hangs up without talking. Block this number

Caller: Called Failed

Didnt answer mobile number, turned 'Show Caller Id' off, and rang back, which resulted in Called Failed

Added to blocked numbers

Called and when I picked up the other party didn't speak. Hung up shortly after.

Caller: Government rebate

I’m on the do not call list they’re still calling me I told them not to call me again and the lady tried to argue with me (Indian lady)

Calls at 7pm, only says “Australia” typical spam.
Blocked

Read call Sat and today (Monday) around 1.30pm.
Phone didn't even ring just said missed call but was on phone using text and no did not ring. This has happened a few times with different nos.

Keeps calling
But you can't call back 😕
Blocked and reported

as previously reported - think scam - blocked

Caller: most likely not human

Caller hangs up as soon as I answer.
Most likely a robot caller checking to see if the number it dials gets answered.
I'll most likely get a call later on from the proper scammer
Have blocked the number but probably a waste of memory as a different number will be used next time.

As everyone else says, suspect scam call
