The state of small business in South Australia

Most writing about South Australian business is either a media release or a warning. This is neither. What follows is the published data on how many businesses trade here, what they do, how big they are, which sectors carry the most strain, and what an owner can reasonably take from any of it.

Every figure below carries its source and its date. Where a number is easy to misread, I've said so plainly, because a statistic about a market is a description of what already happened. It isn't a forecast about your business.

One thing to be straight about first. ADL Business Coach doesn't deliver coaching. It's a matching service: an Adelaide owner describes what's going on, and ADL Business Coach introduces them to up to 3 coaches, each of them a separate, independent Adelaide business. Those coaches pay ADL Business Coach a fee for the introduction, and that fee is how the site is funded.

How many businesses South Australia actually has

South Australia had 174,310 actively trading businesses at 30 June 2026, up 3.3% over the year, which was the second-fastest growth of any state (ABS, Counts of Australian Businesses, June 2026 release, checked 1 September 2026).

That growth figure gets quoted a lot, and it's worth understanding what sits underneath it. A count of actively trading businesses moves on entries and exits together. A rise means more businesses registered and stayed registered than closed. It doesn't mean the average business got bigger, hired anyone, or made more money. Registration and trading health are 2 different things, and only 1 of them is in that number.

Most South Australian businesses have nobody on the payroll

The single most defining fact about business in this state is size. Non-employing businesses, meaning sole traders and businesses with no employees, make up 67.3% of the total. Businesses with 5 or more staff number 19,820 (ABS, Counts of Australian Businesses, June 2025, checked 1 September 2026).

Read that again with your own business next to it. Roughly 2 thirds of the businesses in South Australia are 1 person. The overwhelming majority of the rest are small enough that the owner still knows every customer by name and still does at least part of the delivery work personally.

This matters more than it looks. It explains why so much generic business advice lands badly here: it was written for a company with a finance function, a marketing manager and a middle layer that can absorb a change. In a 1-person or 4-person business, every improvement competes directly with billable hours. That constraint, not a lack of ambition, is why most owners postpone the work that would make the business easier to run.

What South Australians actually do for a living

Source: ABS, Counts of Australian Businesses, June 2025 release, checked 1 September 2026. Division names are shortened in the chart.

Construction is the largest division at 27,626 businesses, well clear of anything else. Rental, hiring and real estate follows at 20,958, then professional, scientific and technical services at 17,228 and agriculture, forestry and fishing at 16,287. Transport, postal and warehousing sits at 14,591 and health care and social assistance at 13,694. Further down: retail trade 9,023, other services 8,198, administrative and support 7,517, financial and insurance 7,120, accommodation and food services 6,908 and manufacturing 6,628 (ABS, Counts of Australian Businesses, June 2025).

2 things stand out. Construction isn't just the largest sector, it leads by a wide margin, which is why a downturn in building work shows up in the state's numbers faster than a downturn almost anywhere else. And agriculture ranks 4th, which is unusual among the states and is the reason a grape price collapse in the Barossa or the Adelaide Hills is a South Australian economic story rather than a regional footnote.

Where those businesses sit geographically is its own subject: the northern corridor is trades, transport and manufacturing, the CBD is professional services and hospitality, the eastern and inner south is health, legal and accounting, and the Hills, Barossa and Alexandrina are agriculture and wine. The guide to Adelaide's business precincts maps that properly.

What these counts don't measure

Before going further, it's worth knowing the edges of this dataset, because they change how much weight any of it can carry.

The ABS counts are built from business register data, so a business appears when it's registered and active for tax purposes. That means a genuine, trading, profitable business and a dormant entity somebody keeps alive for 1 invoice a year can both sit inside the same total. It also means the counts say nothing at all about revenue, profitability, hours worked, or whether the owner has paid themselves this quarter.

Division-level data has a second limit. A division like "other services" bundles together businesses with almost nothing in common, and "professional, scientific and technical services" holds a sole-trader bookkeeper and a 40-person engineering firm in the same row. So the industry mix is a reliable guide to the shape of the state economy and a poor guide to what any 1 business inside a division looks like.

None of that makes the figures less useful. It just means they answer "what does South Australia look like" rather than "how is my sector doing", and those are different questions.

The sectors carrying the most pressure

2 published measures point the same way.

Food and beverage services in South Australia had a 52.8% 4-year survival rate, the lowest 4-year survival of any large South Australian sector (ABS business survival data, SA, checked 1 September 2026). And since July 2021, accommodation and food has been the state's number 1 division for company insolvencies at 535 companies, ahead of construction at 379 (ASIC insolvency statistics, as at 1 September 2026).

Both of those deserve care rather than alarm. A 4-year survival rate counts businesses that stopped trading, which includes owners who sold, retired, changed structure, or simply decided they'd had enough. It isn't a count of failures. And an insolvency count is a raw number, not a rate: accommodation and food has 6,908 businesses in the state, and a division with more businesses will generally record more insolvencies than a smaller one.

Both sectors get their own treatment. What SA insolvency data tells owners about their own risk works through what the ASIC numbers can and can't say about a specific business, and why Adelaide hospitality businesses struggle to make it past year 4 goes into the cost structure behind that 52.8%.

The survival gap, and the honest reading of it

There's 1 more figure worth putting on the table, and it's the one most often misused. In building construction in South Australia, businesses with 5 to 19 staff survived at 89.3% over 4 years, against 50.6% for non-employing builders (ABS business survival by employment size, Construction division, South Australia).

That's a wide gap and it's a real one. What it isn't is an instruction to hire.

The data shows an association, and the causation runs both ways. Businesses that were already working, already winning steady contracts and already generating enough margin to carry a wage were the ones in a position to hire in the first place. Hiring also changes a business: it forces systems, it spreads the load, it stops the whole operation halting when the owner is sick. Both of those things are true at once, and no published figure separates them. Anyone who tells you the number means "hire staff and you'll survive" has read it backwards.

The pressures owners name themselves

The pressures reported across South Australian small business are consistent: labour shortages, insurance and input costs, cash flow, energy costs, and succession or exit.

Insurance, energy and input costs are the ones that arrive as a bill and get absorbed quietly, usually out of the owner's own margin, because re-pricing feels riskier than wearing it. Rising costs in South Australia goes through what the current published figures actually show, including 1 direction that surprised people this year.

Succession is the slower pressure and the more expensive one to ignore. A large share of South Australian businesses are family-owned, and in agriculture and wine especially, the handover question and the business question are the same question. Succession planning for SA family businesses covers the operational side of that, and preparing an Adelaide business for sale covers what a buyer looks at first. Neither replaces your accountant and your lawyer, and both say so.

The pressure specific to the Hills and the Barossa right now is different again, and it's affecting real local families. Running a business through a grape price collapse treats it as an operating problem rather than a headline.

Free and subsidised help exists, and most owners never use it

Before anyone pays for advice, South Australia has publicly funded support that costs nothing or close to it: small business support officers through the state government, a free dispute resolution service, a free financial counselling helpline for businesses in trouble, and subsidised capability programmes.

I'd rather send you there first than take an enquiry a free service would have answered better. Free and subsidised business advice in South Australia lists what's actually running, checked on each programme's own official source, with the date it was checked.

That post exists because most owners genuinely don't know these services are there, and because a matching site that never mentions the free options isn't worth trusting on anything else.

What the numbers change about your own decisions

Here's the honest limit of everything above. State-level data tells you what the weather has been. It tells you nothing about your business specifically, and it can't.

What it's genuinely useful for is 3 things.

1. Calibration. If you're a sole trader wondering whether you're behind for not having staff, you sit inside the 67.3% majority. That's the normal shape of a South Australian business, not a failure to grow.
2. Sequencing. If you're in food and beverage or building construction, the published record says the margin for error in those sectors is thinner than average. That's a reason to cost jobs and roster more deliberately than a business in a gentler sector needs to, not a reason to panic.
3. Timing. Grants and subsidised programmes open and close. Insurance and input costs move on their own schedule. Knowing roughly when things move is worth more than reacting after the invoice lands.

Reading your own business against the state figures

If you want to do something with this page beyond reading it, take an hour and write down 4 numbers for your own business: revenue over the last 12 months, gross margin, how many hours a week you personally work, and how much of the revenue depends on you being in the room.

Those 4 tell you more about your position than any state statistic will. Most owners can't produce all 4 from memory, and that gap is usually the real finding.

If you'd like someone experienced to look at the whole picture and tell you what they see, that's what business advisory is for, and it's a different job from coaching. Coaches in the network work with owner-operators across South Australian industries, at the size most South Australian businesses actually are.
