Single vs family OSHC: does adding dependants actually cost more per person?
How the four OSHC insured group categories are structured and priced, and why a family policy is one policy rather than several separate ones.
Students bringing a partner or children often assume family OSHC works like buying several single policies and stapling them together. It does not. Under the OSHC Deed commencing 1 July 2025 a family policy is one policy in one of four defined categories, and the category — not the number of people — is what the insurer prices against.
This article explains the four categories, what changes when you move between them, and how to get a quote that reflects the people actually on your visa.
One policy, not several
The Deed defines exactly four Insured Group categories. These are the only structures available:
| Category | Who is covered |
|---|---|
| (a) | The Overseas Student only |
| (b) | The Overseas Student and their Partner |
| (c) | The Overseas Student and their Dependant Children |
| (d) | The Overseas Student, a Partner and their Dependant Children |
Note the structure of category (c): student plus dependant children, without a partner. If you have a child and a partner, you are in category (d). You cannot hold category (b) and category (c) as two separate policies to get the same result — a student with a partner and a child is one policy in category (d).
The definitions that decide who falls where are precise. A Dependant is a Partner plus any Dependant Children. A Partner is a spouse or de facto partner who is an eligible family member for the purposes of a Student visa. A Dependant Child is a child, adopted child or step-child who is an eligible family member for your Student visa.
That last clause is the operative one, and it is worth pausing on: eligibility for your visa decides who goes on the policy, not your own household arrangement. The test is an immigration law test. Our family OSHC guide covers the definitions in full.
What changes when you add people
The statutory minimum does not change. Whatever category you are in, the Dee’s Schedule 1 minimum applies identically: public hospital services at 100% of the charges raised by the public hospital, out-of-hospital medical services at a minimum of 85% of the MBS fee, in-hospital medical at 100% of the MBS fee, emergency ambulance, PBS prescriptions, and capped waiting periods.
So the cover content is the same floor everywhere. What differs is the commercial side:
- The premium is set for the category, and it covers the whole insured group for the period. Clause 8.1 of the Deed is explicit: “one premium will apply for each Insured Group, for each OSHC product.” That is why the answer to “does each person cost more” is not simply a multiplication — you are not buying N single policies, so there is no statutory per-head line item to point at. What the per-person cost works out to depends on how the insurer prices that category, which is a commercial decision the Deed does not fix. (Clause 8.2 caps a first-purchase percentage discount at 12 per cent, and clause 8.3 bars insurers from applying an excess.)
- The pharmaceutical minimum changes with the category. Schedule 1 sets a minimum total benefit of $500.00 per calendar year for an Overseas Student alone, and $1,000.00 per calendar year for each of the other Insured Group categories — categories (b), (c) and (d). The per-item cap stays at $50.00 in every case. So moving from single to family changes your PBS minimum from $500 to $1,000 a year, and that is a real, statutorily-mandated difference.
The cleanest way to think about it: you are not buying N single policies. You are buying one policy in a defined category, and the category is what the insurer prices and what the Deed’s benefits are calculated against.
Waiting periods when you add someone mid-term
If you start a single policy and add a partner or child partway through, the category has to change, because category (a) will no longer describe who is covered. That raises the waiting period question, and it is worth being careful about how the answer is framed.
What the Deed actually says is that Schedule 4 sets maximum waiting periods measured from the OSHC start date, and that “a waiting period served under a previous OSHC Product will be off set against, or credited towards, the waiting period of a new OSHC Product, provided there is continuous cover.”
So the statutory framework gives you two protections, and neither is a promise that an added member is automatically clear of waiting periods:
- The caps are ceilings, not fixed periods. The pre-existing condition row allows a maximum of 12 months and the psychiatric row a maximum of 2.
- Where you have already served a waiting period under a previous OSHC product, that time is credited against the new product’s waiting period, as long as cover has been continuous.
What the Deed does not prescribe is the commercial mechanics of a mid-term addition — when an added member’s cover commences, and whether any waiting period applies to them specifically. That is a product term, set by the insurer and described in your Policy Disclosure Statement. Ask the insurer directly, and do not assume either that the added member is clear or that they inherit a full fresh wait.
The Private Health Insurance Ombudsman confirms that the pharmaceutical minimums are the ones that move by category. The rest of the cover floor does not.
Getting a quote that reflects your actual situation
The most common quoting error is getting a single-student quote and discovering at enrolment that the visa names a partner or children. The fix is procedural:
- List everyone on your Student visa, including any partner and dependant children.
- Identify the correct category from the four above — (a), (b), (c) or (d).
- Get a quote in that category, for your exact cover dates.
- Check the pharmaceutical minimum on the quote matches your category ($500 for single, $1,000 for each other category).

The insurers quote you directly for your dates and category, so the figure you see is the figure you pay — we do not publish indicative premium ranges, because insurer pricing changes and a stale range would mislead you.

Key takeaways
- A family policy is one policy in one of four categories, not several single policies stapled together.
- The category is what is priced and what the Dee’s benefits attach to.
- The statutory minimum is identical in every category — cover content is not where policies differ.
- The PBS minimum does change by category — $500 a year for single, $1,000 a year for each other category, $50 per item in all cases.
- Who qualifies is an immigration question — eligible family member for your Student visa, not your household.
- Waiting periods are capped and creditable, not eliminated. Clause 8 of Schedule 4 means a served wait is credited on continuous cover.
- Get quoted in the right category before you enrol, not at enrolment.
