Immediately contact your bank and lodge a fraud complaint.
They will probably do a recall, which has not been successful with most victims.
Unfortunately it means you more than likely will never get your money back.
Contact the OTHER bank too! They need to freeze the account. Email them all the evidence and give them the reference numbers you would have obtained from police, ACCC etc.
If you don't get your money back, lodge a complaint with the Financial Ombudsmen here: https://www.afca.org.au
And ASIC - Australian Securities & Investments Commission https://asic.gov.au/
