Received this call at 6.54am this morning.. As I was asleep I didn't hear it. And also the number is similar to a company that I deal with. So I called it back from my landline as I have a unlisted number, and got a recorded message it was not able to be connected.
So I think it was a scammer o just adding that it could be related to the call that I received later in the morning which I have posted that number here as well...
BEWARE though these are scammers claiming to be from Centrelink...
