Helping young adults stay covered for longer
As of 1 January 2026, dependent children can stay covered on a parent or guardian’s policy until the day before they turn 31 so long as they aren’t married or in a de-facto relationship. If they don’t meet this criteria, HBF has a range of flexible hospital and extras cover options for young adults to choose from.
Here’s what you should know as your children get older:

My child is turning 18
There’s nothing you need to do when your child turns 18. Dependent children can be covered on a family policy for no extra cost until they turn 21 (or 31 if they’re studying full-time), leaving you to focus on celebrating your child’s coming of age without worrying about their health insurance. If your child isn’t currently covered by your policy and you would like to add them, contact us today and we can also check if your current cover is still suitable for your needs.
Approaching 21
Dependent young adults can remain covered on your family policy once they turn 21 if they’re not married or in a de-facto relationship. As they approach age 21, we’ll reach out to you to ask if they’re studying full-time and if so, their expected study end dates. If your dependent young adults are studying full-time, the policy will stay the same and they will continue to be covered at no extra cost. Keep in mind, if your young adults’ circumstances change, you must contact us to let us know.
If any dependent young adult is not studying full-time, we’ll transition the policy to an extended family policy. While the cost of the policy will increase, dependent young adults can remain covered until they turn 31 so long as they’re not married or in a de-facto relationship.
Turning 31
As your young adult approaches age 31, they’ll need to think about their own private health insurance. If they don’t take out their own cover but decide to do so later, they may need to re-serve waiting periods. If they decide to take out cover after 30 June following their 31st birthday, the Australian Government’s Lifetime Health Cover loading (LHC) will apply. LHC is applied by the government to encourage Australians to get hospital cover earlier in life.
If your young adult takes no action, they’ll be automatically removed from your policy on their 31st birthday and they will no longer be covered by HBF. Learn more about health insurance for young adults.
Between 21 and 31
Cover for full-time students
Before your young adult’s 21st birthday, we’ll ask you to log in to myHBF to confirm if they’re studying full-time. Full-time students can stay covered under a family policy at no extra cost until they finish their studies or turn 31 - whichever happens first.
Cover for non-students
If you tell us your young adult isn’t studying full-time, provided they aren’t married or in a de-facto relationship, they can stay on your policy until they turn 31 for an additional cost. This option helps parents support their children for longer, allowing them to stay covered while they set themselves up in life.
Frequently asked questions
What is a student declaration?
What’s the difference between family and extended family cover?
A family policy allows dependent children up to the age of 21 (or age 31 if they are all studying full-time) to be covered by the same policy as their parent/guardian.
An extended family policy allows dependent children over the age of 21 and up to the age of 31 who are not studying full-time to be covered under the same policy as their parent/guardian for an additional cost.
Dependent children can be covered by a family or extended family policy so long as they’re not married or in a de-facto relationship.
What if one of my young adults is studying full-time, and the others are not?
Your cover will be transitioned to an extended family policy. If all of your young adults are studying full-time and you have declared this to us, you will remain eligible for a family policy. You can check your policy details in myHBF. If anything doesn’t look right, please contact us.
Do I have to keep my young adults covered until age 31?
No, you don’t need to keep your young adults covered until age 31. Keep in mind, if they are studying full-time and are not married or in a de-facto relationship, they can remain covered at no extra cost until age 31, or until their circumstances change - whichever happens first.
If you decide to remove your young adult from your policy, any waiting periods served under your current membership will carry over which means they won’t have to re-serve them if they take out their own cover within two months.
To make any changes to your policy, please contact us and we’d be happy to discuss your options with you.
How much extra is extended family cover?
It depends on the level of cover you have. We’ll include a quote for extended family cover when we write to you asking about your young adult’s study status. If you’d like to discuss your health cover needs, please contact us and we’d be happy to help.
What if my young adult’s circumstances change?
You must contact us and let us know. Examples of a change to circumstances include if your young adult’s estimated study end date changes, they get married or are in a de-facto relationship.
I’m on a single parent policy. Can my young adult remain covered until they turn 31?
Yes. Young adults can remain covered under a parent’s policy so long as they are not married or in a de-facto relationship. Extended family cover costs more, so it’s important to weigh up your options before making any changes.
Why is HBF making this change?
By giving parents the option to cover their young adults until they turn 31, we’re providing our members with greater flexibility over their cover as their children get older.
Can I update my young adult’s circumstances online?
If your young adult’s circumstances change – for example, they decide to stop studying full-time, please contact us to discuss your options.
Can my young adult make their own claims?
Young adults covered by a family policy can make their own extras claims if they have their own HBF member card. For hospital claims or to check coverage, we recommend young adults contact us first before seeking treatment.
Can my kids get their own HBF card?
Yes, but their parent/guardian must order it for them. Children aged 16 years and over can get a digital card provided their parent/guardian has already ordered a physical card.
Young adults 18 years and over can get their own digital card through myHBF or HBF App.
What excess does my young adult have to pay if they remain on my policy?
Young adults covered by a family or extended family policy are not required to pay an excess for hospital treatment.
What if I don't tell you about my young adult’s circumstances?
When your young adult turns 21, we’ll transition your policy to extended family cover and the price of your premium will increase.
If we ask you to re-confirm if your young adult is still studying full-time and we don’t hear back from you, we’ll transition your policy to extended family cover and the price of your premium will increase.
Will my young adult need to pay the Medicare Levy Surcharge?
Young adults covered by family or extended family policies which include hospital cover are considered to hold an appropriate level of private patient hospital cover for Medicare Levy Surcharge (MLS) purposes. For individual advice on the applicability of the MLS, we recommend you speak to a professional tax agent.
