This number 1300 302 357) is a scam, purporting to come from ANZ bank. I rang ANZ bank and they confirmed that this is not one of their numbers.
They had scraped my real name and mobile number from somewhere, and the call sounded convincing (except that ANZ does not contact people like this), but it's all FAKE.

Potential Scam
"This is an important message for Mr/s/z <firstname> <lastname> from ANZ, please contact us on 1300 302 357 between <hours mon-fri, sat>"

ANZ website does not show this number on their contacts directory page.
ANZ has no record of the number in their directory (confirmed by two ANZ staff).
ANZ had no record of attempting to call me.
Reported to ANZ scam number (ANZ website)
Apparently a number of reports already put in to ANZ for this number
returning the call sounds like a legitimate ANZ site but robot voice asks for id information immediately and provides an apparently legitimate ANZ call back number (on their website).

Its an anz scam

same experience as above.

They left a message saying it was ANZ with a very important reason. The message had my name. I returned the call. Digital message had my day and month of birth and asked me to confirm the year. It didn’t recognise my year of birth and digital message ended. I rang ANZ and they advised they had not attempted to contact me. Do not respond to this call. Call the bank directly
