Caller: Westpac aparently

You have not yet deposited the cheque we sent you.

Caller: Claimed to be westpac

Obvious scam.

Claimed to be renumiration team.
My phone number isn't attached to that old account from years ago.
Didnt ask for my DOB only to repeat a code they sent then asked for bank account to deposit in.
Didn't ask if ok to record (another red flag)

I purposely answered with incorrect answer to a security question asking what email os attached and password to online bankong, and they said it all checked out.

From St George bank apparently about not depositing a cheque - even included a reference number - quite sophisticated

SCAM…no doubt about that. Text message received from St George about a payment we are owed for an acc. Cheque sent & not yet deposited. This number is not for St George or Westpac.

I just got the SMS this time is says it's St George, A reminder we owe $9.05 We sent a cheque and it hasn't been deposited. We propose to split the payment equally amount all account holders. Blah Blah Blah

Caller: Text

Apparently have a cheque waiting to be deposited that they sent out

This is a legitimate Westac number.
