Hyperbaric Oxygen Therapy for Australian Patients: Clinical-Grade 2 ATA in Thailand

Australian patients seeking clinical-grade hyperbaric oxygen therapy (HBOT) face a challenging landscape at home. Public hospital hyperbaric units operate with long waiting lists and are restricted to a narrow set of Medicare-approved indications. Private access is limited, expensive, and geographically concentrated in major metropolitan areas. For Australians who need a sustained course of HBOT at therapeutic pressure, travelling to a well-equipped international facility is often the most practical option.

Longevity Thailand in Chiang Mai operates a Thai FDA-approved hard shell hyperbaric chamber at 2 ATA (atmospheres absolute), offering Australian patients access to clinical-grade HBOT within a well-established medical tourism destination. This article covers the current state of HBOT in Australia, why 2 ATA pressure matters, what our chamber delivers, and how to plan your treatment trip.

HBOT Availability in Australia

Australia has a small number of hospital-based hyperbaric medicine units, located primarily in major cities including Sydney, Melbourne, Adelaide, Fremantle, and Townsville. These units provide critical services for conditions approved under Medicare and established clinical guidelines, including:

Medicare-funded indications. Decompression illness (diving injuries), gas gangrene, carbon monoxide poisoning, chronic non-healing wounds, radiation tissue injury, and selected soft tissue infections. Access for these conditions is covered but often involves waiting periods.

Limited scope beyond approved indications. For patients seeking HBOT for sports rehabilitation, post-surgical recovery, neurological conditions, chronic inflammation, or longevity optimisation, public hospital units are generally not an option. These applications fall outside the approved indication list, and referral pathways are typically unavailable.

Private sector constraints. A small number of private hyperbaric facilities exist in Australia, but they are few in number and concentrated in select cities. Session costs at private Australian facilities are substantial, and for patients requiring 20 to 40 sessions, the cumulative expense can be prohibitive.

Geographic challenges. Australia’s vast geography means that many patients live hours from the nearest hyperbaric facility. For someone in regional Queensland, Western Australia, or Tasmania, accessing regular HBOT sessions at a metropolitan hospital represents a significant logistical and financial commitment.

Soft shell alternatives. Some Australian wellness centres offer mild hyperbaric sessions using portable soft shell chambers at 1.3 ATA. These devices do not achieve clinical-grade pressure, do not deliver pure oxygen through a BIBS system, and should not be confused with medical-grade HBOT. The clinical evidence supporting therapeutic outcomes is based on protocols using hard shell chambers at 1.5 to 2.4 ATA.

Why 2 ATA Clinical-Grade Pressure Matters

The therapeutic effect of HBOT depends directly on the pressure at which treatment is delivered. This principle is governed by Henry’s Law: the amount of gas dissolved in a liquid is proportional to the pressure of that gas above the liquid.

At 2 ATA, breathing near-pure oxygen through a built-in breathing system (BIBS) produces an arterial oxygen partial pressure (PaO2) of approximately 1,400 mmHg. Under normal breathing conditions, PaO2 is roughly 100 mmHg. This more than tenfold increase in plasma-dissolved oxygen drives the key physiological mechanisms that underpin HBOT’s clinical benefits:

Enhanced tissue oxygenation. Oxygen dissolved in plasma travels independently of haemoglobin, reaching compromised tissues, including ischaemic, inflamed, and post-surgical areas, that red blood cells cannot access efficiently.

Angiogenesis. The cyclical pattern of hyperoxia during treatment and normoxia between sessions promotes new blood vessel formation, improving long-term perfusion in affected tissues.

Stem cell mobilisation. Published research has demonstrated that HBOT at therapeutic pressures increases circulating stem and progenitor cells, supporting the body’s endogenous repair mechanisms.

Anti-inflammatory modulation. HBOT at 2 ATA influences cytokine signalling and reduces markers of oxidative stress, effects that are not reliably observed at sub-therapeutic pressures.

Soft shell chambers at 1.3 ATA produce only modest increases in dissolved oxygen and do not replicate these physiological responses. For a comprehensive review of the science, see our detailed article on HBOT at 2 ATA: why pressure matters.

Our Chamber in Chiang Mai

Longevity Thailand operates a purpose-built hard shell hyperbaric chamber that meets the clinical standard for therapeutic oxygen therapy:

2 ATA operating pressure. The chamber delivers treatment at 2 atmospheres absolute, the pressure level supported by the majority of clinical HBOT research and established treatment guidelines.

BIBS oxygen delivery. Patients breathe near-pure oxygen at 90% or greater purity through a dedicated built-in breathing system mask or hood. This ensures consistent, high-concentration oxygen delivery throughout each session.

Hard shell construction. The chamber is a rigid, medical-grade device with precise pressure control, continuous monitoring instrumentation, and full safety systems. This is fundamentally different from portable soft shell units.

Dual-occupancy design. The chamber accommodates two users simultaneously, enabling patients to share a session with a companion or allowing efficient scheduling for intensive treatment courses.

Thai FDA approval. All HBOT protocols are delivered under full Thai Food and Drug Administration regulatory compliance. Sessions are supervised by trained hyperbaric technicians with physician oversight.

Safety systems. The chamber includes emergency depressurisation capability, continuous pressure and oxygen monitoring, patient-operator communication systems, and fire suppression measures consistent with international hyperbaric safety standards.

Travel from Australia to Chiang Mai

Getting from Australia to Chiang Mai is straightforward, with well-established routing options from all major Australian cities.

From Sydney and Melbourne. The most common route involves a connection through Bangkok’s Suvarnabhumi Airport. Total travel time is approximately 11 to 13 hours depending on the layover. Several airlines operate daily services on the Sydney to Bangkok and Melbourne to Bangkok legs, with frequent onward connections to Chiang Mai (approximately 75 minutes).

From Brisbane, Perth, and Adelaide. Connections are available through Bangkok or regional hubs such as Singapore or Kuala Lumpur. Travel times vary between 12 and 15 hours depending on routing and connection times.

Visa requirements. Australian passport holders receive visa-free entry to Thailand for stays of up to 30 days. No advance application is necessary. For patients planning a longer treatment course, a 60-day tourist visa can be obtained from the Thai consulate before departure, or an e-visa can be applied for online prior to travel.

Airport transfers. Chiang Mai International Airport is compact and easy to navigate. Transfers to the clinic and accommodation areas typically take 15 to 30 minutes. Our patient coordination team arranges private airport transfers on request.

Climate and timing. Chiang Mai’s most comfortable season runs from November through February, with cooler temperatures and clear skies. This period coincides with the Australian summer, making it a convenient time for treatment. However, the clinic operates year-round and the clinical environment is fully air-conditioned.

Planning an Extended Treatment Course

HBOT requires sustained, repeated sessions to achieve cumulative therapeutic benefit. Australian patients should plan for an extended stay in Chiang Mai.

Course length. Depending on the clinical indication, treatment courses range from 10 to 40 sessions. Each session lasts 60 to 90 minutes at pressure, with additional time for pressurisation and depressurisation.

Session frequency. Protocols typically involve one to two sessions per day, five to six days per week. A 20-session course can be completed in approximately two to three weeks.

Typical stay duration. Most Australian patients stay for two to four weeks, depending on their protocol. Some patients complete an initial intensive course and return for follow-up sessions at a later date.

Cost comparison. Even accounting for return flights, accommodation, and daily living expenses, the total cost of an HBOT treatment course in Chiang Mai is typically a fraction of what comparable treatment would cost at an Australian private facility, where such access is available at all. A detailed, transparent quotation is provided after your pre-arrival assessment.

Accommodation. Chiang Mai offers excellent accommodation at a range of price points, all significantly more affordable than equivalent options in Australian capital cities. Options include luxury hotels with full amenities, serviced apartments with kitchen facilities for longer stays, and boutique hotels near the clinic. Our coordination team provides tailored recommendations based on your treatment schedule and preferences.

Recovery environment. Beyond the clinical setting, Chiang Mai offers a pace of life, access to fresh food, and range of wellness amenities that many Australian patients find beneficial for recovery. The city’s massage traditions, yoga studios, and natural surroundings provide a supportive complement to intensive medical treatment.

Combining HBOT with Regenerative Treatments

Many Australian patients use their time in Chiang Mai to access a broader range of regenerative therapies alongside HBOT. Evidence suggests that combining HBOT with complementary treatments may enhance clinical outcomes.

Stem cell therapy. HBOT creates an oxygen-rich tissue environment that may support stem cell survival and engraftment following injection. Pre-conditioning with hyperbaric oxygen can improve the tissue conditions into which cells are delivered.

Exosome therapy. Hyperbaric oxygen may enhance tissue receptivity to exosome-mediated regenerative signalling, potentially amplifying the benefits of exosome protocols.

NAD+ infusions. Combining HBOT with NAD+ therapy targets multiple mechanisms of biological ageing simultaneously, addressing both tissue oxygenation and cellular energy metabolism.

Peptide protocols. Peptides such as BPC-157 and thymosin beta-4 may complement HBOT through their effects on tissue repair, angiogenesis, and anti-inflammatory modulation.

Your physician will design an integrated protocol based on your clinical assessment and treatment goals. For further detail, see our articles on HBOT combined with stem cells and exosomes and HBOT with NAD+ and peptides.

Continuity of Care for Australian Patients

One of the most important aspects of medical travel is ensuring that your care continues seamlessly after returning to Australia.

Pre-arrival coordination. Before you travel, our medical team reviews your health history, existing imaging, pathology results, and medication lists. Any recommended pre-travel blood tests can be completed at standard Australian pathology providers such as Laverty, QML, or Melbourne Pathology.

Treatment documentation. We provide comprehensive treatment summaries in a format suitable for sharing with your Australian GP or specialist. These documents detail all treatments administered, clinical rationale, biomarker results, and recommended follow-up.

Telehealth follow-up. Scheduled video consultations with your treating physician are available at defined intervals after treatment. This ensures ongoing clinical oversight and allows protocol adjustments based on your progress.

Remote biomarker monitoring. Follow-up blood tests can be completed at any Australian pathology service, with results reviewed by our medical team. This enables objective tracking of treatment outcomes without requiring a return visit.

GP liaison. Our physicians can communicate directly with your Australian GP or specialist to ensure coordinated ongoing care. We understand the importance of maintaining a collaborative relationship with your primary healthcare provider.

Insurance considerations. HBOT for wellness, longevity, and elective rehabilitation is generally not covered by Australian private health insurance or Medicare. Patients should budget for treatment as an out-of-pocket expense. We recommend travel insurance that covers medical treatment abroad.
