Diagnostic Imaging Services in Australia: Market Size, Businesses & Forecast 2026

The Diagnostic Imaging Services industry in Australia provides essential medical imaging procedures, including X-rays, ultrasounds, CT scans, and MRIs, to assist in patient diagnosis and disease monitoring. The industry operates within a highly structured framework heavily subsidized by the federal government's Medicare Benefits Schedule (MBS). According to the Australian Institute of Health and Welfare (AIHW), 10.8 million Australians received at least one Medicare-subsidised diagnostic imaging service in 2024-25 (AIHW Pathology, imaging and other diagnostic services report). In total, the sector delivered 32.2 million diagnostic imaging services during the 2024-25 period (AIHW Pathology, i

What does the Diagnostic Imaging Services in Australia industry cover?

This industry consists of independent clinics, specialized practices, and hospital-based units primarily engaged in providing diagnostic imaging services directly to patients upon medical referral. These clinical services use non-invasive radiation, magnetic fields, and high-frequency sound waves to produce detailed internal anatomical views. Key modalities within this defined scope encompass general X-rays, medical ultrasounds, computed tomography (CT), magnetic resonance imaging (MRI), mammography, nuclear medicine, and positron emission tomography (PET) scans.

• •Primary services cover both diagnostic examinations and interventional radiology procedures such as image-guided biopsies and pain management injections.
• •Operations exclude general medical practices, specialized pathology analysis labs, and firms primarily manufacturing or wholesaling medical imaging hardware.
• •Clinical outputs are interpreted by accredited radiologists and nuclear medicine physicians who deliver formal diagnostic reports back to the referring medical practitioners.

Who operates in the industry and how is it structured?

The Australian market exhibits a mixed structure characterized by several large, national corporate consolidators operating alongside a large volume of small, independent community clinics and regional practices. A majority of diagnostic imaging services are delivered in non-hospital, community-based settings to optimize patient access and regional coverage. The Australian Diagnostic Imaging Association (ADIA) acts as the peak industry body, representing private and not-for-profit radiology practices that operate across hundreds of locations nationwide.

• •In the broader diagnostic sector, 91% of combined Medicare-subsidised pathology and imaging services were delivered in non-hospital settings in 2024-25 (AIHW).
• •The sector employs a highly specialized workforce comprising registered radiographers, sonographers, nuclear medicine technologists, and specialized nursing staff.
• •Corporate clinic networks heavily utilize centralized digital health infrastructure and Picture Archiving and Communication Systems (PACS) to distribute radiologist reporting workflows across regional hubs.

What drives demand in the industry?

The primary drivers of volume growth within the industry are Australia’s aging demographic profile and a rising societal prevalence of complex chronic diseases like cancer and cardiovascular conditions. Furthermore, federal public health screening initiatives and ongoing technical advancements in scanner resolution accelerate referral rates from primary care practitioners. Government health statistical reports show a long-term increase in per-capita utilization of medical imaging, solidifying its role as an indispensable diagnostic tool.

• •The proportion of the Australian population receiving at least one diagnostic imaging service reached 39.7% during the 2024-25 financial year (AIHW).
• •The overall volume of diagnostic imaging services rose to a rate of 118 services per 100 people in 2024-25, up from 102 services per 100 people in 2014-15 (AIHW).
• •Targeted national health policies, such as the National Lung Cancer Screening Program, actively utilize localized radiology networks to fulfill early intervention objectives.

Who are the notable companies in the industry?

Competition in the Australian market is fought on clinical reputation, geographic location network, technology availability, and billing policies. Large ASX-listed healthcare corporations command significant market share through multi-regional clinic brands, while competing with agile localized operators. Notable real entities active in the Australian diagnostic imaging sector include corporate providers with extensive multi-state footprints.

• •Sonic Healthcare Limited operates a dominant Australian radiology division consisting of eight practice groups across more than 130 radiology centres.
• •Integral Diagnostics Limited is a prominent ASX-listed specialized diagnostic imaging provider operating extensive clinic networks across Australia and New Zealand.
• •Capitol Health Limited operates a prominent network of community-based diagnostic imaging clinics, primarily trading under the 'Capital Radiology' brand.
• •Healius Limited has historically maintained an extensive nationwide presence in the domestic diagnostic imaging market alongside its core pathology divisions.

What are the recent trends and outlook?

A key trend shaping the industry is the commercial pressure arising from increasing operational costs relative to historical government funding and indexation freezes. Rising patient out-of-pocket costs have emerged as a significant structural barrier, threatening affordable care and causing some patients to defer necessary medical examinations. Moving forward, the industry is focused on securing structural policy reforms and capitalizing on technological enhancements such as artificial intelligence triage tools.

• •The reintroduction of Medicare indexation for X-ray, ultrasound, and CT scans occurred in July 2020 after a historical 22-year policy freeze (ADIA).
• •Historical industry analysis from the ADIA identified that upfront patient out-of-pocket fees for primary care radiology services averaged $227 per service.
• •Historical Australian Bureau of Statistics (ABS) survey data cited by the ADIA indicated that approximately 300,000 patients annually had foregone recommended radiology services due to out-of-pocket costs.

How is the industry regulated?

The sector operates under stringent federal and state regulatory frameworks governing radiation safety, practitioner licensing, and corporate billing compliance. Providers must meet strict accreditation standards to maintain eligibility for government funding and insurance reimbursements. Key legislative structures govern which medical equipment qualifies for public subsidies, heavily influencing corporate equipment procurement and capital investment strategies.

• •Diagnostic imaging items must comply with specific rules set out under the federal Medicare Benefits Schedule (MBS).
• •Medical practitioners, including radiologists and nuclear physicians, are subject to professional registration requirements via the Medical Board of Australia and Ahpra.
• •The industry has historically navigated complex capital rules, such as the federal 'licence' system that regulates which specific MRI scanners can access Medicare rebates.
