Australia’s small business sector isn’t a supporting act in the national economy—it is the economy. With more than 2.6 million small businesses operating across the country, making up 97.3% of all enterprises, these operations are the engine room of Australian commerce. Yet beneath these headline numbers sits a far more nuanced reality of growth hurdles, cash flow pressures, and the pivotal role that strategic finance plays in turning ambition into results.
For Sydney-based business owners, that reality is especially pointed. New South Wales is home to the highest number of businesses of any state—more than 870,000—and Greater Sydney alone accounts for nearly 595,000 small businesses, roughly 70% of the NSW total. The city’s SME density means competition is fierce, costs are elevated, and the margin for financial missteps is thin.
Martin Iglesias of Highfield Private has dedicated his career to guiding Australian SMEs through the financial complexities that come with scaling a business. Based in Sydney and working with companies ranging from $35 million to over $1 billion in turnover, his on-the-ground perspective offers practical insights for local business owners looking to understand—and overcome—the funding challenges that can determine whether a growth trajectory succeeds or stalls.
Australia’s SME Sector at a Glance
Data from the Australian Small Business and Family Enterprise Ombudsman shows the country is home to roughly 2.66 million small businesses (those employing 0–19 people), which account for the vast majority of Australia’s 2.73 million total enterprises. Medium-sized businesses with 20–199 employees make up just 2.5%, and large businesses with 200 or more employees represent a slim 0.2%.
Those figures speak volumes about the entrepreneurial DNA of the Australian economy. They also underscore the sheer diversity of needs, capabilities, and pain points within the SME community—a diversity that’s amplified in a city like Sydney, where a manufacturer in Western Sydney faces vastly different financial pressures to a professional services firm in the CBD.
“Many SMEs will have one or two really big clients,” Iglesias observes. “Should they lose these, they’re in pretty dire straits because they don’t have a wide spread of customers. It’s a very short funnel they’re working with, particularly in the business-to-business sector.”
Punching Above Their Weight: SMEs Drive Employment and Output
The workforce numbers add another layer to the story. In 2023–24, small businesses employed approximately 5.17 million Australians—around 39% of private sector employment across selected industries. In NSW alone, small businesses account for roughly 40% of the state’s private sector workforce. Medium-sized firms nationally accounted for 3.38 million workers (26%), while large businesses employed 4.66 million (35%).
The trend is worth watching closely. While small business employment has held relatively steady, medium and large business headcounts have been climbing. Between 2021–22 and 2023–24, medium business employment jumped from 2.99 million to 3.38 million, and large business employment grew from 4.21 million to 4.66 million.
The economic output story follows a similar pattern. Small businesses contributed $596 billion in value-added to the Australian economy in 2023–24—32% of total private sector value creation. Medium enterprises added $416 billion (23%), and large firms generated $823 billion (45%).
These figures reinforce something Iglesias encounters in his day-to-day work with Sydney businesses: while small enterprises are plentiful, making the leap to medium or large scale demands sophisticated financial strategies and timely access to the right capital.
The Working Capital Crunch
The data makes one thing clear—growth for small businesses isn’t typically constrained by a lack of demand or capability. More often, it’s strangled by working capital. The problem becomes especially sharp when businesses land contracts with major customers who insist on 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 to 90 days, or even longer.”
For Sydney SMEs, that gap between outlay and income can be compounded by the city’s elevated operating costs. Commercial rents in the Sydney CBD have climbed to an average of $1,771 per square metre gross, and even flexible workspace now runs at a median of $1,000 per desk per month—costs that don’t pause while you wait on a client to settle an invoice. A business can look profitable on paper whilst being desperately short on cash in practice. Layer on rising energy costs and wage pressures, and borrowing becomes even harder—particularly for those who weren’t prepared for the squeeze.
“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 real cashflow difficulty.”
Warning Signs in Cash Flow Management
With more than 20 years of experience at ANZ Bank and Commonwealth Bank before moving to Highfield Private, Iglesias has sharpened a keen instinct for the warning signs that signal trouble ahead. And in a market like Sydney—where the failure rate for small businesses sits slightly above the national average at around 6% annually—spotting those signs early is critical.
The most alarming red flag? “A desperate call from the financial controller because they need approval to make payroll payments,” he says. “That immediately signals serious cash flow management issues.”
But less dramatic indicators can be equally revealing. Key warning signs include:
- Balance sheet mismatches: Significant receivables sitting uncollected alongside payables that have blown well past their due dates
- Working capital deficits: Revenue figures that look healthy on the surface, but an inability to actually cover outgoing obligations
- Breaching banking limits: Even when it comes down to timing, repeated breaches point to cash flow that isn’t properly aligned
- Tax arrears: A red flag that makes lenders especially nervous—and one that 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 confirm there are no tax arrears and no active payment plans.”
This is particularly relevant given the federal government’s recent commitment to additional ATO funding over the next four years to enhance tax enforcement and data-matching compliance activities—a signal that scrutiny on business tax obligations is only increasing.
Where Does This Leave Sydney’s Small Businesses?
The numbers tell a compelling story: Australia’s commercial landscape is overwhelmingly shaped by small businesses, yet the employment and economic contribution data reveal that scale carries real weight. Medium and large enterprises generate a disproportionate share of both jobs and economic value, which creates a strong incentive for smaller operators to pursue growth.
But growth takes more than a solid product and a willingness to hustle—especially in a city where overheads are among the highest in the country and SME business conditions in NSW have weakened relative to other states. The NAB Quarterly SME Business Survey noted that NSW had some of the weakest SME conditions nationally in mid-2025, alongside Victoria. For Sydney business owners, that backdrop makes proactive financial planning not just advisable but essential.
For the 595,000 small businesses across Greater Sydney—and the 2.66 million nationally—the road to sustainable growth increasingly calls for the kind of expertise professionals like Martin Iglesias bring to the table: deep technical financial knowledge, real-world sectoral experience, and the strategic clarity to match funding solutions with long-term business goals.
As lending landscapes continue to shift and economic conditions evolve, the SMEs that take a strategic approach to financing—getting their financial house in order before they need capital, rather than scrambling to catch up—will be the ones best positioned to scale into the medium and large business ranks that drive an outsized share of Australia’s economic growth.
