- Branch Network Updates: A significant number of new BSBs assigned to specific physical branch locations across NSW, VIC, QLD, and WA (e.g., St Marys, Liverpool Plaza, Camberwell, and Queen Street Mall).
Bano (Bolt Financial Group) Expansion
The fintech sector is alive and kicking. Bano has added a massive 132 new BSBs, all based in Sydney. This bulk addition (mostly in the585-xxx range) suggests a significant scaling up of their operations or a restructuring of their customer account numbering system.
Other Notable Changes
- Citi (Citibank): Recorded 10 deletions, continuing the consolidation trend we've seen in recent times.
- Cuscal & NAB: Both institutions have processed a number of modifications (25 and 14 changes respectively), likely updating settlement support details or branch addresses.

What This Means For You
For most everyday Aussies, these changes happen in the background. However, if you manage a business or finance department:- Update Your Systems: Ensure your payroll and payment software is updated with the latest BSB file to avoid rejected payments, especially for new Westpac or Bano accounts.
- Check Templates: If you have saved payment templates for Citi accounts, verify they are still valid given the recent deletions.
