What Respiratory Scientists Do in Australia
Respiratory Scientists run lung function tests and overnight sleep studies that underpin the diagnosis of asthma, chronic obstructive pulmonary disease, sleep apnoea, interstitial lung disease, and cystic fibrosis. The work is hands-on and patient-facing. A typical day mixes spirometry, gas transfer testing (DLCO), body plethysmography, FeNO measurement, polysomnography setup, and CPAP titration. Most scientists work inside hospital respiratory and sleep medicine departments, though private sleep clinics are a growing employer.
Demand is concentrated in tertiary public hospitals — the Royal Prince Alfred in Sydney, the Alfred and Austin in Melbourne, Royal Brisbane and Women's, and Sir Charles Gairdner in Perth all run busy lung function laboratories. The Australian and New Zealand Society of Respiratory Science (ANZSRS) is the professional body, and its certification (CRFS) is the de facto credential employers look for. Sleep medicine has expanded sharply since 2020, and most metropolitan hospitals struggle to fill overnight sleep scientist rosters.
The occupation is small. Australia trains only a few dozen new respiratory scientists each year through bachelor's programs at Charles Sturt University, La Trobe, and the University of Sydney. That tight pipeline is exactly why the role appears on the CSOL — and why overseas-trained applicants with strong physiology backgrounds find work quickly.
ANZSCO Code 234612 — What It Covers
ANZSCO 234612 describes a scientist who conducts lung function tests to support the diagnosis and treatment of respiratory and sleep disorders, in consultation with other medical professionals. The classification sits inside Unit Group 2346 (Medical Laboratory Scientists), but Respiratory Scientist has its own dedicated code rather than falling into the broader 234611 or 234699 categories.
Tasks listed under the official ANZSCO description include calibrating respiratory testing equipment, performing spirometry and gas transfer tests, conducting bronchial provocation challenges, setting up ambulatory and in-laboratory sleep studies, analysing diagnostic data, and reporting findings to clinicians. Applicants should make sure their employment references describe these specific duties — not generic "medical laboratory" language, which can trigger a recoding to 234611.
If your work is predominantly biochemistry or haematology rather than respiratory and sleep physiology, you may be assessed under 234611 Medical Laboratory Scientist instead. The two codes are not interchangeable for migration purposes — check the skills assessment bodies list before lodging.
Skills Assessment — VETASSESS
VETASSESS is the sole assessing authority for Respiratory Scientist. The occupation falls into Group A, which means VETASSESS expects a degree-level qualification in a closely related field plus post-qualification employment in the role.
Requirements:
- Qualification assessed at Australian Bachelor degree level or higher
- Highly relevant field: Respiratory Science, Medicine, Clinical Studies, Human Biology, or Life Science with strong physiology content
- At least one year of post-qualification employment in the nominated occupation undertaken in the last five years
- Employment must be at an appropriate skill level (Skill Level 1) and at least 20 hours per week
Assessment fee: AUD $1,096 offshore / AUD $1,205.60 onshore (includes GST). Priority Processing adds AUD $825 offshore or $907.50 onshore.
Processing time: 8-10 weeks for standard assessment.
Common rejection reasons: The biggest failure mode is qualification mismatch. A general biology or pure biochemistry degree without substantial human physiology content is often assessed as insufficiently relevant. The second common pitfall is employment evidence that describes the applicant as a "technician" rather than a scientist — VETASSESS looks for evidence of clinical interpretation, equipment validation, and reporting authority, not just test administration.
VETASSESS updated its information sheet for Respiratory Scientist in February 2026, adding new integrity checks on qualification and employment claims. Document any clinical authority you hold (CRFS, ANZSRS membership, supervising junior scientists) — it strengthens the assessment.
Visa Pathways for Respiratory Scientists
Because 234612 is on the CSOL but not the MLTSSL, you cannot use the Skilled Independent (189) or Skilled Nominated (190) routes. Employer sponsorship is the working pathway.
Subclass 482 — Skills in Demand Visa
The dominant route for overseas-trained respiratory scientists. Employer-sponsored, lasts up to 4 years, and provides a transition to permanent residency via subclass 186.
- Visa fee: AUD $3,210 (primary applicant, 2025-26 indexation)
- Salary requirement: Above the Core Skills Income Threshold (CSIT) of AUD $76,515, rising to $79,499 from 1 July 2026
- Processing time: Most decisions in 1-3 months for employers with accredited sponsorship status
- Quirk: Public hospital networks (NSW Health, Queensland Health, Alfred Health) are experienced sponsors with streamlined nomination processes. Private sleep clinics sponsor less often but increasingly do for senior roles
Most respiratory scientist salaries comfortably clear the CSIT but sit below the Specialist Skills threshold of $141,210, putting applicants in the Core Skills stream.
Subclass 186 — Employer Nomination Scheme
Permanent residency through employer sponsorship. The most common route after 2+ years on a 482.
- Visa fee: AUD $4,910 (primary applicant)
- Streams: Temporary Residence Transition (TRT) for current 482 holders, or Direct Entry for offshore applicants with 3+ years experience
- Processing time: Direct Entry stream typically 6-15 months; TRT stream faster
- Quirk: Public hospitals are large employers comfortable with both streams. Direct Entry needs a positive VETASSESS assessment regardless of how long you've been employed
State Nomination
Because Respiratory Scientist is on the CSOL but not the MLTSSL/STSOL, the state nomination route via 190 and 491 is not currently open in 2026. State health departments do, however, sponsor 482 visas directly through their hospital networks — and that effectively functions as state-backed sponsorship.
NSW Health, Queensland Health, and South Australia Health are the most active sponsors of respiratory scientists. Western Australia has high demand at Sir Charles Gairdner and Fiona Stanley. Tasmania occasionally sponsors through the Royal Hobart Hospital.
If you're targeting a specific state, apply directly to hospital networks rather than waiting for a points-based invitation.
Salary and Employment Outlook
| Role Level | Salary Range (AUD) |
|---|---|
| Graduate Respiratory Scientist | $80,000-$95,000 |
| Senior Respiratory Scientist | $95,000-$115,000 |
| Chief / Senior Scientist (HSO P2) | $115,000-$130,000 |
| Sleep Scientist (overnight) | $90,000-$120,000 (penalties add 15-25%) |
| Locum / Casual | $50-$70/hour |
Public hospital roles are graded under state Health Service Officer (HSO) award scales — for example, Queensland Health pays HSO P1 around $88,000-$120,000 plus 12.75% employer super and 17.5% annual leave loading. Overnight sleep scientists earn substantial shift penalties that push effective annual pay 15-25% above the base.
Private sleep clinics (Respiratory & Sleep Disorders Centre Melbourne, Sleep Health Foundation network, Air Liquide Healthcare) sometimes pay slightly more for senior scientists but offer less defined career progression than public hospitals.
Tips for a Successful Application
1. Pursue ANZSRS Certification Early
The Certified Respiratory Function Scientist (CRFS) and Registered Sleep Scientist (RSS) credentials from ANZSRS aren't legally required but are the de facto standard for senior public hospital roles. Most overseas applicants can attempt the certification exams after demonstrating equivalent training. Holding CRFS substantially shortens employer onboarding and supports your VETASSESS skill-level claim.
2. Choose 234612 — Not 234611
If your work is predominantly respiratory and sleep physiology, nominate 234612 specifically. Some applicants reflexively pick the broader 234611 Medical Laboratory Scientist code because it appears elsewhere on visa lists, but 234611 covers pathology lab science (biochemistry, haematology, microbiology) and will fail if your actual duties are pulmonary function testing.
3. Get Employment References Right
VETASSESS rejection for this occupation often comes down to references that describe the applicant as "performing tests" without clinical interpretation. Have your supervisor explicitly describe your role in protocol selection, result interpretation, equipment validation, and reporting authority. If you've trained or supervised junior staff, name them.
4. Apply Directly to Hospital Networks
The fastest sponsorship route is direct application to public hospital lung function and sleep medicine departments — not generic job boards. NSW Health, Alfred Health, Queensland Health, and St Vincent's Health Australia run their own recruitment portals and have experienced visa sponsorship teams.
5. Document Sleep Medicine Capability
Sleep scientist demand outpaces lung function demand in most Australian capitals. If your background includes polysomnography setup, CPAP titration, and home sleep apnoea testing, foreground that in your CV. It expands the pool of departments willing to sponsor you.
Step-by-Step Migration Roadmap

- Lodge VETASSESS Group A assessment — pay $1,096 offshore or $1,205.60 onshore
- Apply to Australian hospitals — public networks and private sleep clinics; tailor each application
- Receive a job offer with sponsorship — confirm the employer has an active SBS (Standard Business Sponsorship) approval
- Employer lodges nomination — for the Core Skills stream
- Lodge subclass 482 visa application — pay $3,210 and complete health/character checks
- Receive 482 grant — typically 1-3 months for accredited sponsors
- Work in Australia and accrue experience — pursue ANZSRS certification in parallel
- Apply for subclass 186 after 2+ years — TRT stream gives permanent residency
- Settle into permanent residency — eligible for Australian citizenship after 4 years
Frequently Asked Questions
Why isn't Respiratory Scientist on the MLTSSL?
The MLTSSL is reserved for occupations with broad, durable national demand suitable for the points-based system. Respiratory Scientist is highly specialised with a small annual recruitment volume — perhaps 100-200 roles nationally each year. The Department of Home Affairs puts it on the CSOL instead, which routes applicants through employer sponsorship where workforce planning matches need to supply more precisely.
Can a Cardiac Physiologist or Sleep Technician nominate 234612?
Probably not. Cardiac physiologists are usually assessed under a different code (often 251999 Health Professionals nec, or 234611). Sleep technicians without a degree are typically assessed below Skill Level 1 and don't meet 234612 requirements. VETASSESS looks for both the qualification fit and task fit — half-matches fail.
Will the OSCA classification change anything?
The Australian Bureau of Statistics released OSCA 2024 Version 1.0 in December 2024, which renames Respiratory Scientist as 263936 Respiratory or Sleep Scientist. The Department of Home Affairs has not yet adopted OSCA for migration purposes — ANZSCO 234612 remains the operative code in 2026. Track the skilled occupation list updates for transition timing.
How long does the full pathway take from offshore?
Realistic timeline: 4-6 months from VETASSESS application to 482 visa grant if everything runs cleanly. Add another 2-3 years on a 482 before transitioning to 186 permanent residency. Direct Entry 186 from offshore is theoretically possible but rare for respiratory scientists because employers typically want to confirm clinical fit before committing to permanent sponsorship.
What if my degree isn't called "Respiratory Science"?
VETASSESS assesses field relevance, not degree title. A Bachelor of Science with majors in human physiology and biomedical science can be assessed as highly relevant if the coursework includes respiratory physiology, cardiopulmonary anatomy, and clinical measurement. Pull your full transcript and unit descriptions before lodging — VETASSESS reads them line by line.
Are there any state-specific advantages?
Queensland Health and NSW Health run the largest respiratory and sleep medicine networks and are the most consistent 482 sponsors. South Australia has a smaller but highly engaged employer in SA Health. Western Australia and the Australian Capital Territory both have unfilled positions but smaller annual volumes. None offer 190/491 nomination for 234612 in 2026, so target metropolitan public hospital networks directly.
