Caller: Scammer

Claimed to be from my "Australian Bank" and they detected someone trying to transfer funds out of my account. They asked if I wanted to stop the transfer I said yes. They then start talking about sending instructions to me. When asked how they can prove their are legit said don't worry about it they are from the security department. When asked if they can send me a message through the banking app they provided nonsensical response. Hung up on them then.
