Unknown missed call. Could not get a hold of them; they just hung up the phone. Not sure if location caller id is accurate from North West of Sydney

Called but didn't leave a message. Given comments above assumed it was spam call.

Yep, nuisance call. No message. Have blocked them.

I replayed the voicemail and they left a whistling tune for about 10secs. Blocked.

Caller: Dural NSW

Disconnects after one ring when you call back. Call is from Dural

Called them back and did not get a response back with a quick end to the call

Much the same, left a 30second blank message and I didnt call them back.

I've been getting calls from this number and other random landlines since 7th May. The volume itself is unusual because no one calls me that often. My Samsung has listed all of them as Potential Fraud. Other friends have noted an increase in scam/spam calls the last few days.

Caller: Scam caller

No answer and cuts off after 1 ring when you call back.

Caller: No clue

No voicemail & called back but call cuts out immediately. Spam

no message and hang up immediately on calling back

This number called my mobile. I called back from my work landline and it connects and drops out.
