How many companies are there in Australia?

The number

3,992,217 company records, 3,710,066 of them active. Australia has one of the largest and most open company registers in the world relative to its population, because the Australian Securities and Investments Commission publishes the register in bulk.

For context, that is more than five times the size of the Polish register and roughly one company for every seven Australians. The proprietary limited company is used for holding structures, trusts, single-person consultancies and family arrangements as well as for trading businesses, which is why the number is so high.

Active against closed

Nearly a quarter of a million records are deregistered or heading that way. Any list built from a raw register extract without filtering on status will carry those, which is one of the most common sources of bounce and wasted effort in Australian outbound.

Legal forms

Ninety nine percent of the register is one legal form, so legal form carries almost no targeting information in Australia. The useful separators are status, registration age and, where available, industry and location.

Registrations by year

Counts of records registered in each year that are still present in the snapshot.

Formation has grown steadily, with 2025 the strongest year at 367,378. The 2026 figure covers only part of the year and is already above the full-year 2022 total, so the trend is still climbing.

Roughly 7,000 new Australian companies are registered every week. For any supplier of accounting, banking, insurance, software or company services, that is a continuously renewing target list.

What the data does and does not contain

State is present on only about five percent of records. 204,000 carry a state code, led by Victoria with 68,138 and New South Wales with 66,125, then Queensland with 23,845 and Western Australia with 21,214.

That is a limitation worth stating plainly rather than hiding. The Australian register is broad and shallow: it gives you the legal entity, its status, its registration date and its form, and very little else. Industry classification, headcount, revenue and contact detail all have to be added from other sources.

Anyone quoting a four million company Australian database without saying this is describing the row count, not the usable market.

What this means for targeting

Filter on status first. Removing deregistered, strike-off and external administration records takes the working population from 3,992,217 to 3,710,066 and removes the worst of the bounce risk.

Use registration date as the primary segment. With no industry or size data on most records, company age is the strongest signal the register itself provides. Newly registered companies have a defined set of purchases to make and no incumbent supplier.

Expect to enrich. An Australian campaign built on the register alone will reach legal entities rather than trading businesses. The register is the frame; the targeting comes from what you attach to it.

How the count was made

Records come from the Australian Securities and Investments Commission company register, ingested in July 2026 and deduplicated on the Australian Company Number. Status, legal form and registration date are taken directly from the register. Registration year counts include records of every status, not only active ones.

The 2026 row covers registrations to the ingest date rather than a full year.
