# Australia

> What Coverbase asks a supplier in Australia for, and which of those rules block a submission.

[User guides](/user-guides/overview) / [Supplier countries](/user-guides/supplier-countries/overview)

A supplier whose bank account is held in Australia sees the fields below. The country is chosen on the form, and changing it changes the fields, so a supplier is never asked for a detail their country does not use.

## Bank details

| Field                                   | Requirement | Format                                     | Notes                                                             |

### IBAN

An IBAN is optional for Australia. It is up to 34 characters and is checked against the ISO 7064 MOD-97 algorithm, which catches a mistyped or transposed digit before the details reach your finance system.

## Tax and company registrations

| Registration | Requirement | Format                                            | Notes      |
| ------------ | ----------- | ------------------------------------------------- | ---------- |
| ABN          | Required    | 11 characters, digits only, ABN weighted checksum | 11 digits. |

After a registration is saved, Coverbase checks it against the Australian Business Register in the background. That check never blocks the supplier: it annotates the record once it completes, and a reviewer can retry it.

## Country rules

* A supplier's primary address must be a street address. A PO box, GPO box, locked bag or private bag is rejected there; a remittance address may still be one.

## Where these rules come from

Oracle Fusion Cash Management 26c AU validations; ABR ABN checksum; customer policy for the PO box rule.

The rules on this page are confirmed against a primary source, so they are enforced strictly.

Configuration version `2026.09.1`. Your organization can override any of these rules for its own suppliers.
