Australian Bariatric Surgeons Directory 2026: ANZMOSS, Hospital + Years of Practice

ANZMOSS (Australia + NZ Metabolic and Obesity Surgery Society) is the peak professional society for bariatric surgeons in Australia and New Zealand. Membership requires FRACS qualification, current bariatric practice, and adherence to ANZMOSS Position Statements on patient selection, multidisciplinary care, post-operative follow-up, and outcome reporting. It\'s not legally required to perform bariatric surgery, but it\'s the strongest professional credential indicator. Approximately 85-90% of high-volume bariatric surgeons in Australia are ANZMOSS members.

Bariatric surgery has a documented volume-outcome relationship. Surgeons performing 100+ sleeve gastrectomies or bypasses per year have meaningfully better complication rates than surgeons performing under 50 per year. "Years in practice" is a proxy for volume but isn\'t a perfect substitute — ask directly: "How many of this specific procedure have you performed in the last 12 months?" A high-volume surgeon will answer comfortably. A vague answer is a signal.

FRACS (General Surgery) is the broader fellowship — all general surgeons hold it. FRACS (Upper GI) or FRACS (Bariatric) indicates additional subspecialty training in upper gastrointestinal surgery, which is where bariatric procedures are performed. Many highly experienced bariatric surgeons hold General Surgery fellowship + have built bariatric practice through experience rather than subspecialty fellowship. Both can be excellent; the subspecialty signal is one input among many.

Yes — for bariatric surgery, the hospital + multidisciplinary team matter substantially. Look for: dedicated bariatric ward or wing, in-house bariatric dietitian + psychologist, 24/7 anaesthetist coverage with bariatric experience, complications-management protocol (e.g. leak rescue pathway). Hospitals where bariatric surgery is volume-light may lack rescue pathways for rare complications. Most high-quality bariatric surgeons operate at hospitals with established bariatric programs (e.g. Epworth, North Shore Private, St Vincent\'s, Wesley, Hollywood Private, etc.).

Search the AHPRA register (ahpra.gov.au) by name. Every Australian-registered surgeon must hold current AHPRA registration without conditions. AHPRA also publishes any past tribunal decisions. The surgeon\'s AHPRA listing will show their FRACS specialty (General Surgery, with subspecialty interest in bariatric/Upper GI). Cross-check with the ANZMOSS member directory at anzmoss.com.au. If a surgeon is performing bariatric surgery but isn\'t AHPRA-registered as a surgeon, that\'s a major red flag.

A credible bariatric surgeon should offer at least: sleeve gastrectomy (~60-70% of Australian primary bariatric procedures), Roux-en-Y gastric bypass (~15-20%), and revision surgery (for failed sleeves or band conversions). Many no longer offer lap-band as primary procedure — long-term data on lap-band is poor. SADI-S, mini-bypass and BPD-DS are advanced procedures offered by specialist high-volume centres. A clinic that only offers sleeve gastrectomy isn\'t necessarily limited — sleeve is the dominant procedure — but lacks revision capability.

Bariatric surgery has a learning curve documented at ~50-100 cases for sleeve gastrectomy. Surgeons under 5 years post-fellowship may still be moving along this curve — though many newly-qualified surgeons trained in high-volume bariatric centres bring excellent skills. "Years in practice" matters less than recent volume + fellowship-trained outcomes. A 30-year-experienced surgeon performing 10 cases/year may have worse outcomes than a 5-year surgeon performing 200 cases/year. Volume + currency matter more than vintage.

ANZMOSS Position Statement requires: bariatric surgeon (FRACS), bariatric dietitian (APD with bariatric experience), psychologist or psychiatrist, GP coordinator, and post-operative nurse follow-up. Many credible clinics also include: endocrinologist (for diabetes + thyroid co-management), exercise physiologist, pre-operative anaesthetic assessment. If a clinic offers surgery without bariatric-specific dietitian + psychology, the post-op support is probably inadequate — this is a major predictor of long-term outcomes.
