what can scammers do with your bsb and account number

With just your BSB and account number, a scammer usually can’t vacuum cash straight out—this isn’t a magic tap, it’s more like a mailing address for money.

They can attempt dodgy direct debits by faking an authority, exploit invoice‑redirection scams to trick others into paying them, or use the details to look legit in phishing and social engineering. Some will fire tiny test deposits to confirm your name and build a more convincing con later. The real danger comes if they also get your online banking or ID; that’s when accounts can be linked and funds actually moved. Protect yourself: share details only with trusted payers, enable alerts, check statements, and immediately cancel/block unknown direct debits with your bank. If anything smells off, contact your bank pronto and report it to Scamwatch—better a false alarm than a genuine facepalm.
