Mounjaro Cost Australia 2026: What Does Tirzepatide Actually Cost?
Key Takeaways
Mounjaro is the most effective weight loss injection available in Australia — but without PBS support, the costs add up. Here's every cost you need to know, by dose, and how to minimise out-of-pocket expenses.
Mounjaro (tirzepatide) is the most effective weight loss injection currently available in Australia — but without PBS support, the costs can add up. Here's a complete breakdown of what Mounjaro costs in 2026, by dose, and how to keep your out-of-pocket expenses as low as possible.
How Much Does Mounjaro Cost in Australia?
Mounjaro is a private prescription medication for weight management — it is not currently listed on the Pharmaceutical Benefits Scheme (PBS) for this indication. Patients pay the full pharmacy price out-of-pocket. As of 2026, costs vary by dose:
| Dose | Supply | Approx. Monthly Cost |
|---|---|---|
| 2.5mg (starting dose) | 4 pens | $180–$220 |
| 5mg | 4 pens | $220–$260 |
| 7.5mg | 4 pens | $250–$300 |
| 10mg | 4 pens | $280–$320 |
| 12.5mg | 4 pens | $300–$340 |
| 15mg (maximum) | 4 pens | $310–$350 |
These are indicative pharmacy prices and may vary. The medication cost above is separate from the GP consultation — though eligible patients can access bulk-billed telehealth appointments at no out-of-pocket cost through Weight Loss GP Australia.
Is Mounjaro PBS-Subsidised in Australia?
As of June 2026, Mounjaro (tirzepatide) is TGA-registered in Australia for both type 2 diabetes and chronic weight management in adults, but is not yet listed on the PBS for weight management. This means all weight management prescriptions are fully private.
Mounjaro is PBS-listed for type 2 diabetes in patients meeting specific criteria — but prescribing under the diabetes indication when the primary goal is weight loss alone is not appropriate clinical practice.
PBS subsidy applications are assessed by the Pharmaceutical Benefits Advisory Committee (PBAC). If and when Mounjaro is listed for weight management, subsidised prices would be approximately $31 per prescription for general patients ($7.70 for concession cardholders).

Mounjaro vs Ozempic vs Wegovy: Cost Comparison
All three weight loss injections are private prescriptions for weight management in Australia. At maintenance doses:
- Ozempic (semaglutide 1–2mg/week): $120–$220 per month
- Wegovy (semaglutide 2.4mg/week): $200–$280 per month
- Mounjaro (tirzepatide 5–15mg/week): $220–$350 per month
Mounjaro costs more — but produces meaningfully greater weight loss. In the SURMOUNT-1 trial (New England Journal of Medicine, 2022), patients on tirzepatide 15mg lost an average of 20.9% of body weight over 72 weeks — compared to approximately 14.9% for semaglutide 2.4mg in the STEP-1 trial. Assessed on a cost-per-kilogram-lost basis, Mounjaro often compares favourably despite the higher monthly cost.
Is the GP Consultation Cost Covered?
The prescription requires a GP assessment. At Weight Loss GP Australia, consultations are bulk billed for eligible patients under Medicare telehealth item numbers — meaning the appointment costs $0 out-of-pocket. Eligibility depends on your Medicare card status and clinical circumstances, which your GP will confirm at the time of booking.
How to Minimise Your Mounjaro Costs
- Bulk-billed GP consultation — Eliminating the appointment fee is the first step
- Compare pharmacies — Prices vary between dispensing pharmacies; calling ahead is worth doing
- Stay at the lowest effective dose — Many patients achieve their goals at 5–7.5mg without needing to escalate to $350/month
- Monitor PBS developments — A future PBS listing would dramatically reduce costs for eligible patients
Frequently Asked Questions — Mounjaro Cost in Australia
How much does Mounjaro 5mg cost in Australia?
Approximately $220–$260 for a four-week supply (four auto-injector pens), depending on your pharmacy. This is the first maintenance dose after the initial 2.5mg starting phase.
Is Mounjaro cheaper than Ozempic in Australia?
At lower doses the prices are comparable. At higher maintenance doses (10–15mg), Mounjaro is more expensive than Ozempic. However, Mounjaro produces significantly greater average weight loss, so individual cost-effectiveness depends on your response to treatment.
Can I get a rebate for Mounjaro in Australia?
There is no Medicare rebate for the medication cost. Some private health extras policies may cover a partial prescription rebate — check your policy terms. The PBS website lists current subsidised medications; Mounjaro for weight management is not currently listed.
Does Medicare cover the Mounjaro GP consultation?
The GP telehealth consultation may be bulk billed under Medicare telehealth item numbers for eligible patients. The medication cost itself is not Medicare-rebatable for weight management.
When will Mounjaro be on the PBS in Australia?
There is no confirmed timeline. PBAC review processes typically take 12–24 months after application, and the outcome is not guaranteed. The RACGP's obesity management guidelines support pharmacological treatment of obesity as a medical condition, which strengthens the clinical case — but the PBAC also assesses cost-effectiveness relative to alternatives.
