A chief financial officer, or CFO, is the senior executive responsible for managing a company's financial strategy, reporting, and risk. The title appears on the masthead of every major Australian corporation, from ASX-listed giants to fast-growing startups. But what the role actually involves is poorly understood outside finance circles, and even within them, the CFO's scope has expanded considerably over the past decade.
The core responsibilities of a CFO
At its simplest, a CFO owns three things: the numbers, the strategy behind the numbers, and the people who produce them. In practice, that means overseeing financial reporting, managing cash flow, directing the annual budgeting process, and ensuring the company meets its legal obligations to the Australian Taxation Office, ASIC, and any other regulatory bodies with jurisdiction over its finances.
A CFO also sets the framework for internal controls. That includes making sure that no single person in the finance team can approve and pay an invoice, that reconciliations happen on schedule, and that the audit committee of the board has confidence in the numbers it reviews. Without those controls, financial statements can't be trusted, and an untrusted set of accounts is close to useless for any investor or lender.
Day to day, the CFO leads a team that might include a controller, a financial planning and analysis (FP&A) manager, a treasurer, a tax manager, and an accounts payable team. In a smaller business, one person covers most of those roles. In a large company like Wesfarmers or BHP, each function is its own department.
Strategic finance: beyond the books
Modern CFOs spend less time closing the books and more time answering the question: where should the business put its money next? That shift happened gradually as technology automated routine accounting tasks and boards began demanding more forward-looking analysis from their finance chiefs.
A CFO weighing a capital investment will model the project's internal rate of return, stress-test the assumptions, and present the board with a recommendation that accounts for what happens if revenue comes in 20 per cent below expectations. That's not bookkeeping. It's applied decision-making under uncertainty, and it's the kind of work that can determine whether a company grows or stalls.
The CFO also leads the conversation around capital structure: how much debt to carry, when to raise equity, and whether a dividend makes sense at a given point in the business cycle. These decisions have long-term consequences, and they require someone who can translate financial mechanics into plain language for a board whose members aren't all finance specialists.
Fundraising and investor relations
For companies that raise external capital, the CFO is typically the person across the table from investors and lenders. They present the financial case, answer questions about margins and projections, and defend assumptions. A strong CFO can open doors that no amount of product enthusiasm will unlock. A weak one can kill a deal that should have closed.
In the startup world, CFOs often get involved earlier than in established companies. A Series A startup might bring on a part-time CFO or a fractional finance chief specifically to prepare for a fundraising round. The work involves building a financial model, tidying up the cap table, and making sure the company's burn rate narrative is coherent and honest. Investors have seen thousands of decks; a CFO who can't defend the numbers in a room is a liability.
Risk management and compliance
Every business carries financial risk: the risk of a customer not paying, of interest rates rising, of a key supplier going under. The CFO is responsible for identifying those risks, quantifying them, and deciding how to mitigate or accept them. That's a different skill from financial reporting, and it's one that separates average CFOs from exceptional ones.
In Australia, compliance obligations are significant. Companies must comply with the Corporations Act 2001, meet reporting deadlines set by ASIC, and navigate GST, payroll tax, and fringe benefits tax obligations. The CFO doesn't do all of this personally, but they're accountable when something goes wrong. A missed lodgement or a misclassified expense can carry personal liability for a company director, and the CFO often sits on the board.
The difference between a CFO and a financial controller
The two titles are often confused in smaller businesses. A financial controller's job is backward-looking: close the books accurately, produce reliable reports, and maintain the integrity of the general ledger. It's a critical role. It isn't the same as a CFO's.
A CFO looks forward. The controller tells you what happened last month. The CFO tells you what that means for next year and what you should do about it. In a business with revenue under roughly $5 million, the two roles are often held by one person. Above that threshold, most companies benefit from separating them.
When a business needs a CFO
Not every business needs a full-time CFO. A sole trader doesn't need one. Neither does a small partnership ticking along steadily. The need becomes real when financial complexity outpaces what the founder and an accountant can handle together.
Typical triggers include: preparing for external investment, navigating a merger or acquisition, managing rapid growth across multiple entities, or facing a regulatory investigation. At those moments, the cost of a CFO is dwarfed by the cost of getting the finance wrong.
Fractional CFOs, who work across several businesses at once, have become a practical option for Australian small and medium enterprises that need strategic finance capability without the full-time salary. Rates vary widely, but a fractional CFO typically costs between $150 and $400 per hour depending on experience and scope.
What makes a CFO effective
Technical skill is the baseline. A CFO who doesn't understand accounting standards, tax law, or corporate finance basics isn't a CFO worth having. But technical skill alone doesn't make someone effective in the seat.
The best CFOs communicate clearly. They can explain a balance sheet to a non-finance director without condescending. They can push back on a CEO's optimistic projections without destroying the relationship. They build teams that don't depend on them personally, and they create systems that produce reliable information even when they're not in the room.
They're also commercially curious. A CFO who only cares about accuracy and compliance will miss the business decisions that actually move the needle. The role has always required both rigour and judgement. That combination is rarer than it looks from the outside.
