Radiology Benchmarks — National Snapshot
Radiology services are one of the most concentrated medical categories we benchmark — many regions in regional Australia have no on-site radiology at all, with patients travelling to a parent region. The charts below quantify that concentration nationally, by Greater Capital City and by Rest-of-State region, and identify where the catchment gaps are widest.
Radiology Supply — State Breakdown
Australia-wide there is approximately 1 Radiology per 12,702 people across 2,200 verified locations. State-level supply is summarised below.
| State / Territory | Pop per Radiology | Locations |
|---|---|---|
| Australian Capital Territory (ACT) | 1 : 7,458 | 65 |
| Tasmania (TAS) | 1 : 10,871 | 54 |
| New South Wales (NSW) | 1 : 11,511 | 756 |
| South Australia (SA) | 1 : 12,366 | 157 |
| Queensland (QLD) | 1 : 12,731 | 447 |
| Northern Territory (NT) | 1 : 13,523 | 19 |
| Victoria (VIC) | 1 : 13,607 | 531 |
| Western Australia (WA) | 1 : 17,866 | 171 |

About the Radiology Benchmarks
How AreaSearch builds, verifies and benchmarks every Radiology location in Australia.
What's in the dataset
This page is built from AreaSearch's database of verified medical and health service locations across Australia — a continuously maintained inventory of every Radiology provider with a fixed, publicly-listed clinic address. Every record is geocoded to a precise latitude and longitude, validated against public registries and business directories, and assigned to its Australian Bureau of Statistics statistical area for like-for-like benchmarking.
What's deliberately excluded
To keep the supply benchmarks comparable across regions, the dataset excludes any provider without a fixed, verifiable street address. Specifically:
- Mobile and home-visit services — in-home aged care, mobile physiotherapy, NDIS home-based providers, telehealth-only practitioners, and any service delivered without a clinic address.
- Providers without public details — locations whose street address is not publicly listed (e.g. unlisted private specialists who only see referrals, sole practitioners operating from a residential address that is not advertised).
- Unverified entries — a location is only included once AreaSearch has independently confirmed it operates at the listed address.
This means the population-per-provider ratios you see represent the physical, walk-in catchment a resident can reach — not every practitioner who could theoretically deliver care in the area.
Geographic breakdown
Every benchmark is reported at multiple ABS Statistical Geography levels — from the entire country down to a few street blocks — so you can size opportunities at the scale that matches your decision:
- National — one-line summary across all Radiology locations in Australia.
- State — eight states and territories (NSW, VIC, QLD, WA, SA, TAS, NT, ACT).
- Greater Capital City (GCC) — 16 regions splitting each state into "Greater Capital" (metro) and "Rest of State" (regional).
- SA4 — ~89 large sub-state regions (~300,000 residents each) suited to network-scale planning. Available to AreaSearch Pro subscribers.
- SA3 — ~340 mid-sized regions (~30,000–130,000 residents) — suburb clusters and regional towns. Used for the opportunity analysis and distribution profiles.
- SA1 / Mesh Block — ~25,000 SA1s (a few street blocks) and ~33,000 mesh blocks (same building / next door). Used for the closeby and same-block co-location matrices.
How the metrics are computed
- Population per provider — the resident population of the area divided by the count of verified Radiology locations operating in it. Lower is better access.
- Distance to nearest — Haversine geodesic distance from each location to its nearest Radiology neighbour, and to the nearest residential mesh block centroid (a proxy for typical resident travel).
- Gap z-scores — how many standard deviations a region's population-per-provider sits above or below the national mean. Z > 1 = meaningfully under-supplied.
- Co-location rates — of small areas where category A has a presence, the percentage that also have category B. Computed independently at SA3, SA1 and mesh-block scales.
- Cross-category correlations — Pearson correlation of population-per-provider ratios across SA3 regions, showing which categories rise and fall together.
Who uses this data
These benchmarks support healthcare site-selection, network planning and competitive analysis for clinic operators, pharmacy groups, allied health franchises, hospital and aged-care developers, primary health networks, state health departments, REITs and healthcare investors. If you need the underlying location-by-location dataset, SA4 and below benchmarks, or a custom catchment study, contact AreaSearch.
Refresh cadence
The verified location inventory is refreshed continuously as registries publish updates and AreaSearch's verification pipeline confirms changes. Benchmark aggregates on this page are rebuilt quarterly. Population denominators come from the latest Australian Bureau of Statistics Estimated Resident Population release.
