With private health insurance
Note: Medicare rebates apply whether you have private health insurance or not. Your surgeon's practice will typically process Medicare claims on your behalf.
Private health insurance can reduce your out-of-pocket costs from $15,000-$25,000 down to $5,000-$12,000.
You need Gold-tier hospital cover (or equivalent) with bariatric surgery inclusion. Check your policy's Product Disclosure Statement or call your fund to confirm bariatric procedures are covered.
Bariatric surgery is subject to a 12-month waiting period from when you first take out appropriate hospital cover. If you upgrade from a lower tier, the 12 months restarts. Plan ahead.
Even with insurance, you'll typically pay:
Call your health fund and confirm bariatric surgery is included. Ask about gap cover schemes and known-gap doctors.
Get written pre-approval from your fund before booking surgery. This confirms coverage and provides estimated out-of-pocket costs.
Some surgeons participate in health fund "gap cover" or "known gap" schemes, charging limited or no gap fees. This can save $5,000-$10,000.
Request a detailed written quote from your surgeon's practice showing all fees, Medicare rebates, and expected insurance contributions.
Multiple pathways exist to make bariatric surgery affordable, even if you can't pay upfront.
Specialized medical loans from established Australian providers.
Access your super early on compassionate grounds for medical treatment.
Surgery must be necessary to treat a life-threatening condition or alleviate severe pain. Most bariatric patients with obesity-related comorbidities (type 2 diabetes, severe sleep apnoea, cardiovascular disease) qualify.
Direct payment arrangements with your surgeon's practice.
Best for: Patients with stable income who can pay over a shorter term without taking on formal debt. Ask about payment plan availability during your initial consultation.
Short-term payment splitting for deposits and additional costs.
Limitation: Purchase limits too low for total surgery cost. Best used for deposits, pre-op expenses, supplements, or dietitian consultations.
Realistic expectation-setting for the first 12 months post-surgery.
Estimated 12-Month Total Budget
$5,920 - $13,040

While outcomes are generally positive for suitable candidates, bariatric surgery is not a guarantee and requires lifelong commitment:
For appropriate candidates who commit to lifelong lifestyle changes, bariatric surgery represents a significant but worthwhile investment in health, longevity, and quality of life. The combination of immediate health improvements, long-term cost savings, and enhanced wellbeing typically justifies the upfront expense.
Follow these steps to understand your exact costs before committing to surgery.
Schedule consultations with 2-3 Sydney bariatric surgeons to compare approaches, experience, and pricing. Most initial consults cost $200-$350 and are partially Medicare-rebatable.

Common cost and financing questions answered.
Gastric sleeve surgery in Sydney costs $15,000-$25,000 for self-funded patients. With private health insurance and Medicare rebates, out-of-pocket costs typically reduce to $5,000-$12,000. Final costs depend on surgeon experience, hospital choice, and your health insurance coverage.

Yes, you may be eligible to access superannuation early on compassionate grounds to pay for weight loss surgery. This requires medical documentation from two specialists demonstrating the surgery is necessary to treat a life-threatening condition or alleviate severe pain from obesity-related comorbidities. Applications are assessed by the ATO on a case-by-case basis, with processing typically taking 2-4 weeks. Learn more about the process →
Gastric band (lap-band) surgery is typically the lowest-cost bariatric procedure in Sydney at $12,000-$20,000 self-funded. However, it has higher revision rates and lower weight loss outcomes compared to gastric sleeve or bypass. When factoring in long-term effectiveness and potential revision surgery costs, gastric sleeve often provides better value despite higher initial cost. Your surgeon will recommend the most appropriate procedure based on your medical profile, not just cost.
Yes, most Sydney bariatric surgeons offer payment plans through medical finance providers like Total Lifestyle Credit (TLC), Latitude Medical Finance, and Openpay. These typically offer 12-60 month terms at 0-14.9% interest rates. Many surgeons also provide in-house payment plans with deposits of 20-30% and interest-free terms over 6-12 months. Discuss payment options during your initial consultation.
Private health insurance with gold-level hospital cover typically includes gastric bypass and other bariatric procedures, subject to a 12-month waiting period. Insurance covers hospital accommodation and a portion of specialist fees, but gap fees of $3,000-$8,000 are common depending on your surgeon and fund. Check your specific policy for bariatric surgery inclusion and gap cover arrangements. Some funds offer "known gap" or "no gap" schemes with participating surgeons.
Beyond surgery costs, budget for pre-operative tests ($500-$1,500), dietitian consultations ($800-$1,500 first year), psychological assessment ($300-$500), lifelong vitamins and supplements ($60-$120/month), protein shakes during recovery ($300-$600), and potential wardrobe replacement ($500-$2,000+). Total additional costs typically range $3,000-$6,000 in the first year. Most patients find these ongoing costs manageable and worthwhile given the health benefits.
