What Illawarra Radiology Group does

Illawarra Radiology Group is a private diagnostic imaging practice founded in 1960 and headquartered in Wollongong, New South Wales, Australia. It operates four imaging practices across the Illawarra region (Wollongong, Corrimal, Dapto, Shellharbour) plus an X-Ray-only site at Wollongong Medical Centre, delivering a comprehensive multi-modality service line that includes multi-slice CT, 1.5 Tesla MRI (Medicare-licensed), ultrasound with colour doppler, 3D digital mammography, EOS low-dose standing imaging, dental OPG/lateral cephalometry, and image-guided interventional procedures such as biopsies and joint injections. The practice serves two primary customer groups: general public patients (referred by GPs, specialists, and allied health practitioners) and the referring clinicians themselves, who receive results via Fetch, InteleViewer, and the InteleConnect Portal, and submit electronic referrals through eOrders (Best Practice) and eRequests (Gentu, Genie). Patients access images and reports through a Zed Technologies-powered Patient Portal available on web, iOS, and Android.

The business operates a private billing model with Medicare rebates applied per the Medicare Benefits Schedule, bulk-billing available to Healthcare Card and Pension Card holders for the majority of outpatient examinations, and gap/out-of-pocket fees for interventional procedures and certain non-bulk-billed services. Illawarra Radiology Group has been a wholly-owned subsidiary of Sonic Healthcare (ASX: SHL) since its 2000 acquisition, operating as a locally managed, medically led practice within Sonic's decentralized federation of diagnostic imaging entities. The practice holds QIP accreditation as a diagnostic imaging practice and is compliant with Australian Privacy Principles and GDPR for its Patient Portal. Leadership comprises CEO Dr James Linklater OAM (appointed February 2020; musculoskeletal radiologist) and COO Donna Press (oversees 300+ staff across the network). Distribution is referral-led and physical-location-driven, supplemented by digital channels including eReferral integrations, the Patient Portal, and government screening program infrastructure (NLCSP from 1 July 2025, with results uploaded to the National Cancer Screening Register and My Health Record).

Scale indicators3 records

Recent moves7 records

Expansion highlights6 records

Others

• Intelerad Medical Systems: Provides the InteleViewer and InteleConnect imaging platforms used by IRG and many other radiology practices globally. Functions as an infrastructure vendor to the radiology industry rather than a direct competitor.
• Zed Technologies: Technology partner powering IRG's Patient Portal application. Provides patient-facing digital imaging access to several Australian radiology providers and is an adjacent ecosystem enabler rather than a direct competitor.

Regional players

• Lake Imaging: Regional Victoria-based multi-modality diagnostic imaging provider. Operates with a similar regional multi-site model and comprehensive imaging offering, but serves a different Australian geography (regional Victoria vs. Illawarra NSW).
• PRP Diagnostic Imaging: Australian regional diagnostic imaging group offering multi-modality services across multiple NSW locations. Comparable in regional multi-site operating model and service mix to IRG, with overlapping Illawarra/Sydney catchment.

Broad incumbents

• I-Med Radiology Network: Australia's largest radiology network with over 240 clinics nationwide. Directly competes with IRG in multi-modality diagnostic imaging but at significantly larger scale, making it the dominant broad incumbent peer in Australian diagnostic imaging.
• Capital Radiology: Australia-wide diagnostic imaging network with extensive clinic footprint. Competitor in multi-modality imaging across the broader New South Wales market, with similar service portfolio but larger geographic reach.

Direct peers

• Queensland X-Ray: Part of the Sonic Healthcare group, providing comprehensive diagnostic imaging across multiple locations in Queensland. Directly comparable in service mix, multi-site model, and corporate parent to Illawarra Radiology Group.
• Castlereagh Imaging: Sister Sonic Healthcare imaging practice in NSW sharing the same CEO (Dr James Linklater) and COO (Donna Press). Offers multi-modality diagnostic imaging including CT, MRI, ultrasound, and mammography, serving as the closest operational and governance-level peer to IRG.
• Hunter Imaging Group: Another Sonic Healthcare/ASX:SHL imaging network in the Hunter region of NSW. Provides a comparable multi-modality diagnostic imaging service offering and is part of the same Sonic Imaging federation, making it a highly comparable regional peer.
• SKG Radiology: Western Australia-based radiology group also under Sonic Healthcare, offering multi-modality imaging including MRI, CT, ultrasound, mammography, and interventional procedures. Operates as a regional multi-site diagnostic imaging peer.
