How Many Small Businesses Are in Australia? Martin Iglesias Explores SMEs by the Numbers in 2025
Australia's small business sector isn't just a footnote in the nation's economy—it's the main story.
There are more than 2.6 million small businesses in Australia, accounting for 97.3% of all enterprises. These operations form the backbone of commercial activity across the country. But behind these impressive figures lies a more complex narrative about growth, challenges, and the critical role of strategic finance.
Martin Iglesias of Highfield Private has spent his career helping Australian SMEs navigate the financial complexities that accompany their ambitions. His perspective on the sector's dynamics offers valuable insights for business owners seeking to understand and overcome the funding challenges that can make or break growth trajectories.
The Scale of Australia's SME Sector
According to data from the Australian Small Business and Family Enterprise, Australia is home to approximately 2.66 million small businesses (those with 0-19 employees), representing the overwhelming majority of the nation's 2.73 million total businesses. Medium-sized businesses with 20-199 employees account for just 2.5% of the total, whilst large businesses with 200 or more employees represent a mere 0.2%.
These figures tell an important story about the entrepreneurial character of the Australian economy, but they also highlight the immense diversity of needs, capabilities, and challenges within the SME community.
"Many times SMEs will have one or two really big clients," Iglesias observes. "Should they lose these, then they're in pretty dire straits because they don't really have a wide spread of customers. It's a very short funnel that they're working with, particularly in the business-to-business sector."
An Outsized Impact: Small Businesses Employ More & Produce More
The employment picture reveals another dimension of the SME sector's importance. In 2023-24, small businesses employed approximately 5.17 million Australians—representing 39% of private sector employment across selected industries. Medium businesses accounted for 3.38 million employees (26%), whilst large businesses employed 4.66 million (35%).
What's particularly noteworthy is the trend: although small business employment has remained relatively stable, medium and large business employment has been growing. From 2021-22 to 2023-24, medium business employment increased from 2.99 million to 3.38 million, whilst large business employment rose from 4.21 million to 4.66 million.
The economic contribution tells a similarly nuanced story. Small businesses generated $596 billion in value-added to the Australian economy in 2023-24, representing 32% of total private sector value creation. Medium businesses contributed $416 billion (23%), whilst large businesses accounted for $823 billion (45%).
These figures underscore a reality that Iglesias sees daily in his work: whilst small businesses are numerous, scaling to medium and large size requires sophisticated financial strategies and access to appropriate capital.
The Working Capital Challenge
These data prove that growth for small businesses isn't limited by demand or capability. Rather, it's constrained by working capital. This challenge becomes particularly acute when businesses secure contracts with large customers who impose extended payment terms.
"Sometimes with bigger customers, the supplier needs to come up with all of the working capital at the beginning," Iglesias explains. "They might need to wait 60-90 days, or even longer."
This mismatch between outlay and income creates a precarious situation. Businesses may be profitable on paper but cash-poor in practice. Rising inflation complicates borrowing even more for small businesses, especially if they weren’t prepared for the constriction.
"Oftentimes they end up in arrears with tax because they haven't accounted for these working capital outlays," Iglesias notes. "They rely on the Tax Office as a lender of last resort, and that can get them into cashflow difficulty."
Red Flags in Cash Flow Management
With more than two decades of experience at ANZ Bank and Commonwealth Bank before joining Highfield Private, Iglesias has developed a keen eye for the warning signs that indicate a business is struggling with cash flow management.
The most dramatic red flag? "A desperate call from the financial controller because they need approval to make payroll payments," he says. "That shows there are cash flow management issues."
But more subtle indicators can be just as telling. These include:
- Balance sheet mismatches: Large receivables that aren't being collected alongside blown-out payables
- Working capital deficits: An inability to meet payables despite healthy-looking revenue figures
- Breach of banking limits: Even when it's just a timing issue, these breaches indicate poor cash flow alignment
- Tax arrears: Particularly concerning to lenders, this often signals deeper structural problems
"The banks will always seek to get up to date ATO portals, which show running balance statements for taxes," Iglesias explains. "They're providing that to the banks every six months these days, or at least at annual review, to show there's no tax arrears and they're not on payment plans."
What’s Next for Australia’s Small Businesses?
The statistics paint a clear picture: Australia's economy is overwhelmingly driven by small businesses, yet the employment and economic value data show that scale matters. Medium and large businesses punch above their weight in both employment and economic contribution, creating a powerful incentive for small businesses to pursue growth.
However, that growth requires more than ambition and a good business model. It demands strategic financial planning, proactive cash flow management, and access to appropriate capital structures—precisely the areas where many SME owners struggle.
For the 2.66 million small businesses across Australia, the path to sustainable growth increasingly requires the kind of expertise that professionals like Martin Iglesias provide: a combination of technical financial knowledge, sectoral experience, and the strategic insight to align funding solutions with long-term business objectives.
As the Australian economy continues to evolve and lending landscapes shift, those SMEs that approach their financing strategically—getting their financial house in order before they need capital rather than scrambling reactively—will be best positioned to join the ranks of medium and large businesses that drive an outsized portion of the nation's economic growth.
