GLP-1 medications in Australia — tirzepatide, semaglutide, retatrutide
GLP-1 receptor agonists are the most effective weight-loss medications available in Australia today. All three are accessed through an AHPRA-registered Australian doctor — either as a TGA-registered branded product or a compounded SAS-B prescription from a TGA-licensed Australian pharmacy.

What Australian GLP-1 prescribing is not
- Not a 'checkout' — every prescription requires a real clinical review.
- Not offshore — importing GLP-1s yourself from overseas vendors is unlawful under the Customs Act.
- Not a substitute for diet, activity and behavioural change — GLP-1s amplify those, they don't replace them.
- Not first-line for everyone — eligibility depends on BMI and comorbidity profile.
FAQ
What is a GLP-1 medication?
GLP-1 receptor agonists are injectable medications that mimic the gut hormone GLP-1. They slow gastric emptying, reduce appetite and improve glycaemic control. In Australia they're used for type 2 diabetes and — at higher doses — for chronic weight management when clinically indicated.
Which GLP-1 medications are available in Australia?
Semaglutide (Ozempic, Wegovy), tirzepatide (Mounjaro — a dual GIP/GLP-1) and liraglutide (Saxenda) are TGA-registered. Retatrutide (a triple GIP/GLP-1/glucagon agonist) is currently in late-stage trials and only accessible via compounded SAS-B prescribing.
Are GLP-1 weight loss injections legal in Australia?
Yes — when prescribed by an AHPRA-registered Australian doctor. Branded products are dispensed on a private script at any AU pharmacy. Compounded versions are lawful when prescribed under the TGA Special Access Scheme Category B (SAS-B) and dispensed by a TGA-licensed AU compounding pharmacy.
How much do GLP-1 injections cost in Australia?
As a 2026 guide: branded Mounjaro and Wegovy are roughly AUD $400–$650 per month on private script. Compounded tirzepatide or semaglutide is typically AUD $250–$550 per month depending on dose. Initial telehealth consultation with PeptideDoctorAU is $99.
Which GLP-1 is best for weight loss?
In head-to-head trials tirzepatide produced greater weight loss than semaglutide at maximum tolerated doses. Retatrutide (still investigational) showed even larger reductions in early-phase trials. The right choice depends on your goals, comorbidities, tolerance and what's available — your AHPRA-registered prescriber will discuss the trade-offs.
