What Is Section 19AB and Why Does It Matter for IMGs?
Section 19AB of Australia's Health Insurance Act 1973 is the single most misunderstood rule affecting IMGs. It restricts where you can bill Medicare for 10 years from your first medical registration in Australia. Understanding it is the difference between earning from day one and waiting months for the right exemption.
The rule in one sentence
For 10 years from your first medical registration in Australia, you cannot bill Medicare at practices in MM1 locations (inner-metropolitan areas like Sydney CBD, Melbourne CBD, central Brisbane) — unless you have an exemption.
Why it exists
Australia has a geographic maldistribution of doctors. Too many in inner-metro, not enough in regional and rural areas. Section 19AB is the government's lever: it pushes new IMGs toward underserved areas by restricting their Medicare billing in well-served ones.
The MM classification scale
| Classification | Meaning | 19AB restricted? |
|---|---|---|
| MM1 | Major cities (inner metro) | Yes — not DPA, so you need an exemption |
| MM2 | Regional centres | No — automatically DPA |
| MM3–4 | Large and medium rural towns | No — automatically DPA |
| MM5–7 | Small rural and remote | No — automatically DPA, plus incentives |
The Department of Health's rule: Modified Monash 2–7 areas are automatically DPA, Modified Monash 1 inner metropolitan areas are not, and the Northern Territory and Tasmania are DPA. Other catchments are classified against a benchmark of GP services (Department of Health — Distribution Priority Area ↗). Always check the specific practice address at the Health Workforce Locator ↗.
Exemptions that let you bill at MM1
After-hours exemption
Work between 6pm and 8am Monday to Friday, or any time on weekends and public holidays, at any location. The exemption is requested as part of your Medicare provider-number application for the after-hours role. This is the most commonly used pathway for IMGs earning in Sydney and Melbourne.
Spousal exemption
If your spouse "is a medical practitioner or a skilled migrant", you may qualify for an exemption to work in the same location as them. Check the conditions on the Department of Health 19AB exemptions page ↗ before you apply.
Discretionary exemption
The Department can grant a discretionary exemption for medical reasons (you are the primary carer for a close family member with a serious medical condition that can't be managed in a DPA or DWS) or exceptional circumstances (an unforeseen, unavoidable and uncommon event). An "area of need" declaration is not a 19AB exemption: it is a Medical Board registration matter, declared by the state or territory Minister for Health, and does not by itself give Medicare access.
Other listed exemptions
The Department also lists exemptions for the 6-month locum period (once only, while you arrange work in a DPA or DWS — it cannot be extended or repeated), academic appointments with an Australian medical school, approved workforce and training programs, and several others. Check each one's conditions on the Department of Health 19AB exemptions page ↗. For an individual exemption, the Department may take up to 28 working days to assess your application, and it can't be backdated.
DPA work (no exemption needed)
Work at a practice in a Distribution Priority Area. No exemption is needed there — and every MM2–7 location is DPA, so regional and rural GP work is unrestricted.
Split arrangement (not an exemption)
Combine metro after-hours (for income, using the after-hours exemption) with regional daytime (for training credit, in a DPA area). Some practices specifically structure this for newly arrived IMGs.
When does 19AB end?
10 years from your first medical registration in Australia, if you are a permanent resident or citizen by then. While you remain a temporary resident the restriction continues. Scaling credits for rural and remote work can shorten the period (Department of Health — 10-year moratorium and scaling ↗). The clock starts at your first Australian medical registration — the anchor Services Australia uses for the moratorium — and runs even before you first bill Medicare.
Does 19AB apply to Competent Authority doctors?
Yes. 19AB applies to doctors whose medical degree is from outside Australia or New Zealand, whatever their pathway, when they bill Medicare. UK, Irish, American, and Indian graduates are all subject to the same 10-year moratorium. It does not apply to salaried work that does not attract Medicare benefits, such as a public hospital post. The difference is that Competent Authority doctors register and reach the billing stage faster, so their 10-year clock starts sooner. See the Competent Authority timeline to understand how quickly you can reach the billing stage.
