Where you have an existing agency online account (e.g. you have a username and password that allows you to access Centrelink online services) you may “link” that agency online account to your australia.gov.au account.

If you do not have an agency online account you may register for agency online services, (i.e. Medicare and Centrelink) through australia.gov.au. You can then use your australia.gov.au user ID and password to access the agency online services.

If you have an existing online account with Centrelink, Child Support or Medicare, you can link your australia.gov.au account with your agency account.

Have your agency login details nearby when creating a link between accounts:

1. Select the LOGIN button located on the top right of most pages within the australia.gov.au website.
   
   
   
2. Enter your australia.gov.au user ID and password and answer one of your secret questions.
3. You will be taken to the My Account page.
4. Under the My online services heading, click on 'Link to online services'; you will be taken to a list of potential links.
   
   
   
5. Choose 'Centrelink / Child Support / Medicare online services'.
6. Choose the first option: 'I have an existing (Centrelink/Child Support/Medicare) account for the online services that I want to use.'
7. Click 'Continue'.
8. For security reasons, you will need to answer another of your secret questions.
9. Choose which agency account/s you wish to link to your australia.gov.au account from the "Manage Links" page.
10. You'll be taken to that agency's website. While you are there, the agency will check that you are the right person to be accessing your record at the agency.
11. Once the agency has checked you're the right person, you'll be returned to the "Manage Links" page so you can see if the link was successful.
12. To add links to more agency accounts, repeat steps 9-11.
13. Your linked accounts will now display under the My online services heading.
    
    

All details that you supply to an Australian Government agency online service through australia.gov.au are held by that agency in their own systems.  Linking your agency online service to an australia.gov.au account does not cause the information to be held by australia.gov.au.

australia.gov.au does provide the option for you to enter some details for the personalisation of your account.  In the future some information, (such as your address) may be used to answer questions asked through australia.gov.au.  Your permission to do this will always be sought first.

No.  Your australia.gov.au account is anonymous and you may choose to create a new australia.gov.au account for each agency online service you register for.

However, the benefit of having an australia.gov.au account is that you will only need to remember one user ID and password if you do use the same australia.gov.au account to register for different agency online services.

1. Select the Login button located on the top right of most pages within the australia.gov.au website.
   
   
   
2. Enter your australia.gov.au user ID and password and answer one of your secret questions; Upon a successful answer, you will be taken to the australia.gov.au home page.
   
3. Choose the MY ACCOUNT tab, located just below the search box.
   
   
   
4. Under My online services, you will be see a list of agencies you are currently linked to. Click on the agency name to access your agency online account.
   
   
   

Yes. While your australia.gov.au Account will provide you with one user ID and password, your separate accounts will still exist. Your australia.gov.au Account enables access to your agency account information through australia.gov.au.

No.  Any information you provide will not be automatically shared across agencies. If you do choose to provide your personal information, it will only be shared with your consent.
