AI marketing statistics Australia 2026: which numbers to trust

Short answer: Ask how many Australian businesses use AI and you get three different answers: 12% from the Australian Bureau of Statistics (formal AI use, all businesses, 2024-25), 44% from the National AI Centre’s monthly tracker of 400 SMEs (any level of adoption, February 2026), and 69% from Intuit’s QuickBooks 2026 AI Impact Report (regular use, surveyed small business owners, January 2026). None of them is wrong, they measure different populations in different ways. What we could not find anywhere is a credible Australian figure for marketing automation ROI or hours saved, so this page does not quote one.

Most statistics pages pick a number and move on. This one spends more time on where the numbers come from, because that is usually the part being skipped. Three sources give three different pictures of Australian AI adoption, and a set of ROI claims doing the rounds cannot be traced to anything real. Here is what actually holds up, with a source on every figure. For the practical side, see our AI marketing guide for Australian small business.

Why Australian AI adoption is 12%, 44% and 69% at the same time

The Australian Bureau of Statistics released its Characteristics of Australian Business report for 2024-25 on 25 June 2026, based on a survey run October 2025 to February 2026. About 12% of Australian businesses used AI in 2024-25, up from 1% in 2021-22: small and micro businesses around 11%, medium 22%, large 35%. Adoption was highest in information media and telecommunications (38%), then professional, scientific and technical services and financial and insurance services (both 24%).

The National AI Centre, part of the Department of Industry, Science and Resources, runs a monthly tracker of 400 SME owners and decision-makers. It found 43% reporting some AI adoption across December 2025 to February 2026, easing from 45% the quarter before, and 44% in February 2026 specifically.

Intuit’s QuickBooks 2026 AI Impact Report, published 13 May 2026, surveyed 3,790 Australian SMB owners and operators from July 2024 to January 2026. It found 69% using AI regularly by January 2026, up from 40% in July 2024, with 28% using it daily and 12% saying AI is now core to how they operate.

Three real numbers, three methodologies, no contradiction once you read past the headline. The ABS survey is built to represent the whole economy, including the micro businesses and sole traders that have not touched AI, so it lands lowest. The National AI Centre surveys only SMEs and counts any level of adoption, a lower bar on a narrower group, so it lands in the middle. QuickBooks, a software company, asks small business owners whether they use AI regularly, a question that counts everyday tool use, which is why it lands highest. The lesson: ask which population and bar for “using AI” matches your business.

What Australian businesses actually use AI for

Adoption numbers say nothing about what the tool is doing inside the business, and the breakdown matters more than the headline.

Among QuickBooks respondents already using AI, the top applications are data processing (38%), administration (36%), marketing (34%), customer service (32%) and bookkeeping (32%). Marketing sits mid-list, not the top. The National AI Centre tracker finds a similar pattern: content generation and data analytics are tied as the top use case, each at 54% of SME adopters.

The ABS data adds a qualifier: small businesses that were innovating in other ways adopted AI at 19%, against 4% for small businesses that were not. Adoption tends to cluster in businesses already changing how they work.

On outcomes, QuickBooks found 79% of AI-using SMBs reporting productivity gains, 43% increased revenue and 25% reduced costs. Read the fourth figure alongside those three: 21% reported costs rising. Adoption is not automatically a cost saving.

The ROI numbers we left out, and why

The figures usually attached to marketing automation, a 340% average return, a 20 to 40 hour weekly saving, a 4.2 times first-year return, circulate across agency sites with no named study, sample size or date behind any of them. An earlier version of this page quoted them too, and we have taken them out. We looked for a credible Australian source for a marketing automation ROI or hours-saved figure and did not find one, not in the ABS release, the National AI Centre tracker, or the QuickBooks report. All three cover AI adoption generally. None isolates marketing automation or quantifies its return.

That gap does not mean marketing automation fails to pay off. It means the figures used to argue that it does are not verifiable, and an unverifiable number is marketing copy, not evidence. Treat any ROI claim with no attached sample, date or named publisher like any other unsupported sales claim. Our guide on whether marketing automation is worth it for an Australian business covers the actual costs, and our guide to AI automation costs in Australia covers what setup involves.

What AI Overviews are doing to clicks

Google turned AI Overviews on in Australia on 29 October 2024, and the effect on organic clicks has been getting measured since.

Ahrefs studied 300,000 keywords in April 2025 and found that when an AI Overview appeared, the page ranking first saw an average click-through rate 34.5% lower than when none was present. An updated study using December 2025 data, published February 2026, found the gap had widened to 58% lower.

Pew Research Center took a different approach, tracking actual browsing behaviour from 900 US adults in March 2025. It found people clicked a traditional result in only 8% of visits where an AI summary appeared, against 15% when it did not, and clicked a source inside the summary itself in just 1% of visits. That is US behaviour, not Australian. But Australia has had AI Overviews for close to two years, and there is no obvious reason the mechanism, an answer satisfying the searcher before they reach the results, would behave differently here.

Our opinion, not a statistic: being a cited source inside an AI answer is worth chasing in its own right, separately from ranking, and businesses building expertise content now will have a head start over those who wait. See our guides on SEO, AEO and GEO for Australian businesses and on getting cited in ChatGPT and Perplexity.

What 400 business owners say is stopping them

The National AI Centre tracker also asks non-adopters why they have not moved. Around 65% cite distrust of AI decisions or a wish to keep humans in control, and 54% say AI is not relevant to their business, with overlap between the two. Separately, 19% of SMEs say they do not know how to use AI at all.

QuickBooks asked its own customers a similar question and got a more practical answer: 39% cite privacy and security concerns, 31% say they lack knowledge of what AI can actually do. Trust and relevance dominate the broader SME population, while a more tech-familiar group worries more about data handling. Either way, the barrier is rarely the technology itself, it is understanding what it does.

What this means for your ad budget

None of the figures above tell you what to spend on ads, so we are not attaching a number to something we cannot verify. What we can point to are the ranges in our own Australian pricing guides. Google search clicks have a median of about A$3.81 in Digital Nomads HQ’s May 2026 index (Keyword Planner estimates), with legal around A$17.48 and trades around A$9.25. Most small businesses still start with a monthly ad budget of A$1,000 to A$2,500. Full detail is in our guides to Google Ads cost in Australia and digital advertising budgets for small business.

The one number industry averages cannot give you

Every figure on this page describes someone else’s business. The only one that describes yours is the one you record yourself, and it takes about an hour.

Before changing anything, write down five things: enquiries last month, by source. Average time to first reply, checked against real timestamps. How many quotes went unanswered and were never followed up. Your enquiry-to-customer rate. Average customer value. Make one change, wait a month, and record the same five numbers again.

This beats any adoption percentage for a simple reason. A 69% figure tells you the category is mainstream. A 44% figure tells you plenty of businesses your size have not moved yet either. Neither tells you whether a change worked in your business. Your own before-and-after does, and it protects you from concluding AI marketing failed when the real issue is that no baseline was recorded. See our guide to how analytics can fuel your marketing.

Frequently asked questions

How many Australian small businesses actually use AI? It depends which survey you read. The Australian Bureau of Statistics found about 12% of Australian businesses used AI in 2024-25, and about 11% of small and micro businesses. The National AI Centre’s monthly tracker of 400 SMEs found 44% in February 2026, counting any level of adoption. Intuit’s QuickBooks 2026 AI Impact Report found 69% of the small and mid-sized business owners it surveyed using AI regularly. None of the three is wrong. Pick the one whose population and definition match your business.

What is the real return on investment for marketing automation in Australia? We could not find one. The ‘340% return’ figures circulating on agency websites carry no named study, sample size or date, which means they cannot be checked. None of the three sources on this page, the ABS, the National AI Centre or QuickBooks, puts a return or hours-saved figure on marketing automation specifically. Until a credible Australian source publishes one, the only ROI figure worth acting on is the one you measure in your own business.

Why do three different reports give three different AI adoption numbers for Australia? Because they measure different things. The ABS is the national statistics agency, and its business survey is built to represent the whole economy, including the many micro businesses and sole traders that have not touched AI, which is why it lands lowest. The National AI Centre surveys only SMEs and counts any level of adoption, a lower bar on a narrower group, so it lands in the middle. QuickBooks is a software company surveying small business owners about using AI regularly, a question that counts everyday tool use, which is why it lands highest. All three are legitimate answers to different questions.

What do Australian businesses mostly use AI for? According to the QuickBooks 2026 AI Impact Report, the top uses among adopters are data processing (38%), administration (36%), marketing (34%), customer service (32%) and bookkeeping (32%). The National AI Centre tracker finds content generation and data analytics tied as the top use case, each at 54% of SME adopters. Marketing sits inside a broader pattern of administrative and analytical use, not as a category on its own.

How much are AI Overviews cutting into website clicks? Ahrefs studied 300,000 keywords in April 2025 and found an AI Overview correlated with a 34.5% lower average click-through rate on the top-ranking page. An updated study published February 2026, using December 2025 data, found the gap had widened to 58% lower. Separately, Pew Research Center tracked real browsing from 900 US adults in March 2025 and found people clicked a traditional result in only 8% of visits with an AI summary present, against 15% without. That figure is US behaviour, not Australian, but Google turned AI Overviews on here on 29 October 2024, and the direction is unlikely to differ.

What is stopping more Australian small businesses from using AI? The National AI Centre tracker finds around 65% of non-adopters cite distrust of AI decisions or a wish to keep humans in control, and 54% say AI is not relevant to their business. Separately, 19% of SMEs say they do not know how to use AI at all. QuickBooks finds a more practical barrier among its own customers: 39% cite privacy and security concerns and 31% say they lack knowledge of what AI can do.

Should I trust a marketing agency’s AI ROI statistics? Trust the ones that name a source, a sample and a date, and be sceptical of the ones that do not. A ‘340% return’ figure with no attribution cannot be checked, and we could not trace that one to any published survey. That does not make AI marketing worthless. It means the only number you can fully rely on is the before-and-after you measure yourself.
