If you run a small company, a startup, or a business that is finally big enough to need a real leadership structure, you have probably used the words CEO, Managing Director and Director almost interchangeably. On a business card or an About Us page the differences barely matter. Once you start signing contracts, raising capital, or appointing people to roles, they do. The labels describe separate positions with different legal consequences, and conflating them is one of the most common governance mistakes small Australian companies make.
The good news is that the law is more forgiving than most founders expect. It does not punish you for choosing a title that happens to be popular. It does care about who sits on your board, who owes statutory duties, and who has the authority to bind the company. Whether you are choosing your own title or deciding how to structure your leadership team, a little clarity now saves real disputes later.
What the law actually says about the two roles
Under the Corporations Act 2001 (Cth), being appointed CEO does not, by itself, make someone a director. A director is a member of the board. A CEO is the most senior executive responsible for the day-to-day running of the business. The two positions are separate, and a CEO will only become a director if a separate appointment is made following the company's constitution or the replaceable rules.
How directors get appointed
Directors are appointed in one of two ways, depending on what your constitution says. Under s 201G of the Corporations Act 2001 (Cth), which is a replaceable rule, a company may appoint a director by a resolution passed in a general meeting. Under s 201H, also a replaceable rule, the existing directors may appoint a new director by resolution. For a proprietary company, an appointment made by the other directors must then be confirmed by a shareholders' resolution within two months, or the person stops being a director.
What matters is that these are separate steps. Hiring someone as your CEO does not trigger them. If you want your CEO on the board, someone has to pass the resolution that puts them there and the document that records it.
Managing Director is different again
A Managing Director is a different creature, and this is where the confusion usually starts. Under s 201J of the Corporations Act 2001 (Cth), the directors may appoint one or more of themselves to the office of Managing Director. In other words, to be Managing Director you must already be a director. The Managing Director is a director who has also been given executive authority to manage the company.
So there are in effect three common arrangements. A company may have a CEO who is not a director, a Managing Director who is a director, or a CEO who is also appointed to the board. The label alone does not tell you which one you have. What determines it is whether the appointment resolution and the governance documents say the person sits on the board.
The CEO is usually still an "officer"
Even when a CEO is not on the board, they usually carry serious legal obligations anyway. This flows from the meaning of officer in s 9AD of the Act. An officer includes a director or secretary, but it also covers anyone who makes, or participates in making, decisions that affect the whole or a substantial part of the business, or who can significantly affect the company's financial standing. Most CEOs fall into that category.
The duties each role owes
Both roles carry legal responsibilities, although they arise in different ways.
Duties of a director
Directors owe statutory duties in Part 2D.1 of the Corporations Act 2001 (Cth). Under s 180, a director must exercise their powers and discharge their duties with the degree of care and diligence that a reasonable person in their position would exercise. Under s 181, they must act in good faith in the best interests of the company and for a proper purpose. Related provisions prohibit improper use of position and improper use of information. These are serious, and in some circumstances a breach can be a civil penalty matter or even a criminal offence.
Duties of a CEO and other officers
The duty of care and diligence in s 180 and the good faith duty in s 181 apply not just to directors but to other officers as well. That means a CEO who is not a director still owes these statutory duties. On top of that, their employment or service agreement adds contractual obligations about performance, confidentiality, intellectual property, restraints and termination. If a CEO is also a director, both sets of obligations apply at once, and managing conflicts becomes genuinely important, particularly when board decisions touch the CEO's own pay or performance.
The business judgment rule
Directors and officers are not expected to be perfect, which is one reason the business judgment rule in s 180(2) exists. It provides some protection for a decision made in good faith and for a proper purpose, where the person is free of a material personal interest, has informed themselves as they reasonably believe is appropriate, and rationally believes the decision is in the company's best interests. Documenting your reasoning is the practical way to show this protection is available.
When the difference actually matters
It helps to see how these distinctions play out in the situations you are likely to deal with.
Your CEO wants to sign a large contract
A common moment of panic is discovering a CEO has signed something significant and wondering whether it is binding. Under s 126 of the Corporations Act 2001 (Cth), an individual can exercise a company's power to make contracts and execute documents if they act with the company's express or implied authority and on behalf of the company. Whether the CEO has that authority depends on the constitution, any delegation from the board, and the person's actual role. A CEO who is not a director can still have authority, but you want that authority to be explicit and documented so there is no doubt later.
You are choosing between CEO and Managing Director
If you like the title Chief Executive Officer, the main question is whether that person should also sit on the board. Many growing companies keep the CEO off the board so the directors can supervise the executive independently. Others put the CEO on the board, sometimes as Managing Director, to combine leadership with governance accountability. There is no right answer, only a consistent one. If you want the title Managing Director, the person must be a director first, which narrows the choice.
A founder-CEO wears every hat
Founders often hold three roles at once: shareholder, director and CEO. That is common, but it creates friction points. When the founder-CEO's pay is set, new shares are issued, or a related-party deal is approved, the same person is on both sides of the decision. Independent board oversight, careful minutes and a proper conflicts process help make sure those decisions are defensible and fair.
A co-founder believes their role makes them a director
Sometimes two co-founders start a company, one takes the title CEO and the other assumes that makes them both board members automatically. It does not. If the constitution and appointment records only show the second person as a shareholder or employee, they have none of the protections or powers of a director. That misunderstanding tends to surface painfully at the first dispute over strategy or money.
When you might not need help yet
Most of the time, the question of whether a CEO is a director is answered by checking two things: the constitution or replaceable rules, and the resolutions that appointed your people. If you are a sole founder with no investors and no employees, and you call yourself CEO to sound professional on LinkedIn, nothing needs to change. There is no legal requirement to have a CEO, and a title alone does not create liability.
The point at which you should stop and get advice is the first time a second person gets a title, the board starts making decisions, or the company signs contracts, issues shares or raises money through someone other than a founder. That is when the gap between a label and a genuine appointment starts to cost money.
It costs nothing to check. Most commercial law firms offer a free initial consultation, and a five-minute conversation describing your structure will normally give you an excellent steer on whether you have a problem at all, or whether the sensible step is just a clean set of resolutions and a short governance document. Resolving it early is far cheaper than untangling it after a dispute or a signed contract.
The distinction worth carrying with you
The simplest way to hold the whole thing in your head is this: a director sits on the board and owes statutory duties, while a CEO runs the business and is an officer who owes similar duties, and the CEO only becomes a director through a separate appointment. A Managing Director is always a director because the law requires it. Titles are marketing; appointments and duty are law. If you want your leadership roles to mean exactly what they appear to mean, name the positions, appoint them properly under your constitution, and record the decisions. If you are at all unsure whether your current structure matches your titles, a short free conversation with a lawyer will give you a clear steer on whether it is worth cleaning anything up. It is one of the cheapest governance checks a growing Australian business can run.
