At Healthy Weight Australia, we know that the cost of gastric sleeve surgery is a major deciding factor for many people.
Like all bariatric surgery, this is an investment in you—your health, your life, and your future. Increasingly, Australians are self-funding this investment.
In fact, between 2018–19 and 2022–23, self-funded private hospital admissions for bariatric surgery rose from 305,000 to nearly 391,000.
As a leading weight loss clinic in Brisbane and Sydney, we know that financial planning is an important part of deciding to embark on weight loss surgery, so it’s worth understanding the cost of gastric sleeve surgery so you can make the best decision for you.
Average cost of gastric sleeve surgery
Sleeve gastrectomy cost varies based on a number of factors, including the surgeon’s experience, the clinic or hospital where the procedure is performed, geographic location, and whether the surgery is done in a public or private hospital.
So let’s talk broad numbers— in Australia, the average cost of gastric sleeve surgery ranges from $15,000 to $25,000 for self-funded patients, depending on the above variables.

Factors impacting gastric sleeve surgery cost
Depending on your personal situation, there are a number of additional costs that you should factor in when considering gastric sleeve surgery, including the cost of follow-up consultations, dietary supplements, and any complications that may arise during or after the surgery.
As a standard, the following variables can also impact the final bill :
- The location of the surgery : Surgeries in larger cities or private hospitals may be more expensive compared to those in regional areas or public healthcare facilities.
- The surgeon’s experience: As highly experienced or specialised surgeons may charge more due to their skills and track record.
- Private or public hospitals: As different healthcare facilities may have varying costs for the surgery itself, as well as additional fees for anaesthesia, operating room use, and medical staff.
- Inclusions : Some providers offer all-inclusive packages that cover the cost of pre-surgery tests, hospital stay, post-op check-ups, and nutritional counselling. These packages may be more cost-effective than paying for each service individually.
Finally, one of the biggest determining factors for cost is whether you have private health insurance, and if your plan covers part of the cost.
Does Medicare or private health insurance cover the cost of gastric sleeve surgery?
As of November 2025, under item number 31575, Medicare may provide a rebate of $673.65 for gastric sleeve operation cost.
To qualify, you’ll need to demonstrate clinically severe obesity (BMI ≥40 or ≥35 with comorbidities) and have previously attempted other weight loss methods.
Even if you qualify, this rebate often covers only a portion of the total cost, leaving significant out-of-pocket expenses.
If you have private health insurance (with appropriate coverage) this can bring your bill down to approximately $3,500 – $7,500.
However, a 12-month waiting period usually applies for bariatric surgery.
Without private health insurance, you can expect to pay between $14,500 and $25,000, depending on the clinic.
