  • Definition of a dependant

    Your spouse or children are automatically considered dependants.

    We define a spouse as someone who is either:

    • legally married to you
    • not legally married to you but lives with you on a genuine domestic basis in a relationship as a couple.

    We define a child as someone who is either under 18 years old, or is permanently disabled, and is either your:

    • biological child
    • adopted child
    • stepchild
    • child of your de facto spouse.


    If you apply to pay expenses for a dependant who is not defined as your spouse or child, you need to prove you are in an interdependent relationship.

    An interdependent relationship is a close personal relationship between two people which meets all of these conditions:

    • The people live together.
    • One or both provides financial support to the other.
    • One or both provides domestic support and personal care to the other.

    Evidence of interdependency

    To prove you are in an interdependent relationship, you must provide documents showing you both live at the same address. This could be a joint bank statement or a phone, power or water bill.

    You also need to provide a statutory declaration telling us about your interdependent relationship. This statutory declaration should include:

    • how long you’ve been in the relationship
    • if you jointly own a house or belongings
    • if you jointly care and provide support for children
    • if your relationship is known to the public
    • the amount of emotional support you provide each other.

    You may also be considered to have an interdependent relationship if you have a close personal relationship but live apart because one or both of you are temporarily:

    • working interstate or overseas or detained in prison
    • receiving care for a physical, intellectual or psychiatric disability.
