An AUSkey gives you a secure login for online Government services for businesses. These services are more than just changing details, it also is a pathway for business to lodge their business activity statement (BAS).

Obtaining an AUSkey requires a business to verify their eligibility. Essentially, an AUSkey requires an ABN and an eligible associate. Once created, this person will have an administrator AUSkey, businesses are able to apply for subsequent AUSkeys.

You can register for an AUSkey through the ABR.

Manage ABN Connections

An alternative to AUSkey, Manage ABN Connections lets someone connect ABNs to their myGov account where they are given the ability to update the ABN details after securely logging in. The ABR gives details on how to set this up.

Contacting the ABR

The ABR provides other methods, business can contact them directly. Alternatively, there is a form that can be submitted by mail after an order is placed.
