Fiduciary Duties Of Directors, Founders And Key Employees In Australia

If you’re running a small business, wearing “decision-maker” hats is part of the job. You’re signing contracts, hiring people, managing money, pitching to investors, and making calls that shape the future of the company.

But there’s a legal layer underneath all of that which can catch business owners off guard: fiduciary responsibility.

In plain English, fiduciary responsibility is about acting in someone else’s best interests when you’ve been trusted with power, information, or control. For directors and founders, it often comes up when you’re deciding what’s “best for the company” (and not just what’s best for you personally).

This guide will walk you through the practical meaning of fiduciary responsibility in Australia, who owes fiduciary duties, what it looks like in real business scenarios, and the steps you can take to reduce risk and keep your decision-making clean.

What Is Fiduciary Responsibility (And Why Does It Matter For Small Businesses)?

Fiduciary responsibility (often called “fiduciary duty”) is a legal obligation to act in the best interests of another party in situations of trust and confidence.

People often search for “what is a fiduciary duty” or “fiduciary responsibility meaning” because it can sound abstract. But in business, it’s very practical: it’s about how you use your authority.

What Does “Fiduciary” Actually Mean?

A “fiduciary” is someone who has been put in a position where they must prioritise another person or entity’s interests because of:

• trust (they’re relying on you),
• power (you can affect outcomes), and/or
• access to information (you know things others don’t).

In a company context, the “other party” is usually the company itself. That’s a key point for directors and founders: even if you started the business, once it’s a company, it’s its own legal entity.

Why This Matters If You’re Building Or Scaling A Business

Fiduciary obligations matter because they often sit behind the disputes that break businesses:

• founders falling out over ownership and decision-making
• directors being accused of using company opportunities personally
• key employees leaving and taking clients, staff, or confidential information
• side businesses and “conflicts” that weren’t disclosed early

Getting this right early helps you protect the business, maintain investor confidence, and reduce the risk of claims that can become expensive and distracting.

Who Owes Fiduciary Duties In Australia?

Fiduciary duties can arise under different parts of Australian law. For small businesses, they most commonly show up in:

• general law fiduciary duties (judge-made law) where a relationship of trust and confidence exists, and
• statutory and general law directors’ duties (including under the Corporations Act and overlapping general law obligations).

It’s important to note that while directors’ duties and fiduciary duties often overlap in practice, they are not exactly the same thing. A single situation can trigger both sets of obligations.

Here are the common roles where fiduciary responsibility may apply.

Company Directors (Including Founder-Directors)

Directors are the clearest example. Even if you’re also a shareholder, founder, or employee, your director role comes with duties that are not optional.

In practice, directors need to manage fiduciary risk in everyday decisions like:

• approving payments, contracts, and supplier arrangements
• raising capital and issuing shares
• making decisions where a director has a personal interest
• handling company information and strategy

This is also why governance documents matter. A tailored Company Constitution can help clarify internal rules around decision-making, director powers, and procedures.

Founders And Shareholders (Sometimes)

Not every shareholder owes fiduciary duties just because they hold shares. However, fiduciary obligations can arise where a founder/shareholder has:

• control over the company (especially in a small company),
• special influence over other stakeholders, or
• an arrangement that creates a relationship of trust and confidence (for example, in a quasi-partnership style setup).

If you have multiple founders, this is one reason it’s so important to document expectations early. A clear Shareholders Agreement can reduce misunderstandings about conflicts, related-party dealings, exits, and decision thresholds.

Key Employees And Senior Managers

While not every employee is a fiduciary, senior employees (for example, a general manager, head of sales, head of product, or CFO) can owe fiduciary duties depending on their authority and the trust placed in them.

This can show up when a senior employee:

• runs a side business competing with you
• diverts a business opportunity
• uses confidential information for personal gain
• encourages clients or staff to move with them

Well-drafted employment documentation helps reduce ambiguity around expectations, confidentiality, and conflicts. For example, having a tailored Employment Contract is often a practical first step (especially for leadership roles).

Other Fiduciary Relationships You Might Encounter

Depending on how your business is structured and who you work with, fiduciary relationships may also arise in contexts like:

• agents acting on your behalf
• partners in a partnership
• trustees managing trust assets
• some adviser relationships (depending on the facts)

If you’re unsure whether a relationship creates fiduciary obligations, it’s worth getting advice early-because the risk usually isn’t obvious until something goes wrong.

What Are Fiduciary Responsibilities In Practice? (The Core Duties)

People often ask “what are fiduciary duties?” because they want a checklist. While the wording can vary, fiduciary responsibility typically includes these practical obligations.

1. Act In The Best Interests Of The Company (Not Yourself)

If you’re a director, you generally need to make decisions you genuinely believe are in the company’s best interests. That can be tricky in small businesses where your personal and business life overlap.

A common example: approving a supplier agreement with a business you own personally. Even if it’s a “good deal,” the process and disclosure still matter.

2. Avoid Conflicts Of Interest (And Disclose Them Properly)

Conflicts happen in real life. The legal issue is usually not that a conflict exists-it’s that it wasn’t managed properly.

A conflict of interest might include:

• you (or a close family member) having a financial interest in a supplier or customer
• you sitting on the board of two businesses competing in the same market
• you negotiating your own remuneration or bonuses without proper process

As your business grows, it often becomes worthwhile to document how conflicts are identified and handled. A Conflict of Interest Policy can be a practical tool-especially if you have multiple directors, investors, or a not-for-profit style governance environment.

3. Don’t Misuse Your Position

“Misuse of position” is a common theme in director disputes. It usually means using your role and authority to benefit yourself (or harm the company), such as:

• pressuring the company to enter a deal that mainly benefits you
• making decisions to disadvantage another shareholder for personal reasons
• using your authority to block approvals unless you get a personal benefit

4. Don’t Misuse Company Information

This includes confidential business information like pricing, strategy, customer lists, product roadmaps, bids, and internal financials.

A classic risk point is when someone leaves (director or senior employee) and uses what they know to compete, solicit clients, or replicate a product. Even if you have contracts in place, fiduciary duties can still be relevant.

5. Don’t Take Company Opportunities For Yourself

If an opportunity arises because of your role (or because a customer or supplier approached the company), you generally can’t just take it personally.

For example, imagine:

• a customer approaches the company for a large deal, and a director redirects it to their personal business, or
• you learn about a property/site/partnership opportunity through the company, and you buy it privately without offering it to the company first.

This is one of the most common “it felt harmless at the time” issues that later becomes a legal problem.

Common Fiduciary Responsibility Risk Scenarios For Directors And Founders

Fiduciary responsibility isn’t just a “big company” problem. In small businesses, the risks often come from informal decision-making, blurred roles, and undocumented side arrangements.

Related-Party Deals And Founder “Handshake” Arrangements

Small businesses often do related-party deals because they’re convenient:

• renting premises from a director
• using a director’s vehicle or equipment
• engaging a family member’s agency or consultancy

These aren’t automatically unlawful. The issue is whether the director properly disclosed the interest, whether the arrangement was fair to the company, and whether approvals were handled correctly.

Director Loans, Drawings, And “I’ll Pay It Back Later”

Mixing personal and business funds is a common operational reality in early-stage businesses, but it can become a governance and duty issue quickly if it’s not recorded and managed.

If you’re taking money out of the company (or putting money in), it’s important to understand how it should be treated and documented (including from a legal perspective, and also for accounting and tax). For example, this often overlaps with how you document a director loan and what approvals are required.

Note: This section is general information only and isn’t accounting or tax advice. If you’re unsure how a payment should be recorded or treated for tax purposes, you should speak with your accountant or tax adviser.

Side Hustles And Competing Businesses

It’s common for founders and senior employees to have side projects. The question is: does it compete with the company, use company resources, or rely on confidential information?

If it does, you may be in fiduciary duty territory, particularly if the side business was not disclosed or approved.

Founder Exits And “Taking Clients”

When a founder or senior leader leaves, the business can be exposed if:

• key client relationships were managed informally (without strong contracts in the company’s name)
• IP ownership wasn’t documented
• there were no clear restraints/confidentiality expectations

Fiduciary obligations can be relevant here, but it’s much easier to manage risk proactively than to argue about it later.

How Do You Manage Fiduciary Responsibility? Practical Steps And Documents

If you’re thinking, “This all sounds important, but what should I actually do?”-you’re asking the right question.

Managing fiduciary responsibility is mainly about creating clear processes and documentation so decisions are transparent, fair, and defensible.

1. Be Clear On Roles (Director vs Shareholder vs Employee)

In small companies, one person can be all three. The risk is assuming “I own the business, so I can do what I want.”

A company is a separate legal entity. That means you should treat decision-making as company decision-making-particularly when money, assets, or opportunities are involved.

2. Document Decisions (Especially Where There’s Any Conflict)

If a decision could be questioned later, document it now. This might include:

• board minutes or written resolutions
• disclosures of interests
• quotes or benchmarking showing a deal was commercially fair
• clear approvals for related-party arrangements

For smaller companies without formal board meetings, written resolutions are often a practical approach. A Directors Resolution Template can help you keep your records consistent.

3. Put Governance Foundations In Place Early

Good governance isn’t about red tape-it’s about avoiding avoidable disputes. Depending on your business, this might include:

• a Company Constitution setting out internal rules
• a Shareholders Agreement setting expectations between owners
• delegations of authority (who can sign what)
• a conflicts policy and approval process

These documents don’t just “look nice” for investors-they make it much easier to show that directors and key decision-makers acted properly.

4. Protect The Business If You Have Multiple Directors (Indemnities And Access)

Many companies put formal protections in place for directors, including how directors are indemnified and how they can access company records after they stop being a director (which often becomes an issue in disputes).

Depending on your situation, a Deed of Access & Indemnity can be part of a sensible governance pack for your board and your company’s risk profile.

5. Use Strong Employment And Contractor Arrangements For Key People

If your senior staff have access to confidential information, pricing, strategy, or customer relationships, it’s worth making sure your documents match the reality of their role.

A tailored Employment Contract can help set expectations around:

• confidentiality and IP
• conflicts and outside work
• return of company property and information on exit
• handovers and notice processes

6. Build A “Culture Of Disclosure”

One of the simplest ways to reduce fiduciary risk is to encourage early disclosure internally.

For example, if a director is considering a side investment, or a senior manager wants to consult on weekends, it’s usually better to raise it early and manage it properly than to find out after it becomes a problem.

This is particularly true once you have investors or multiple founders-because perceptions of fairness matter, even when nobody intended to do the wrong thing.

Key Takeaways

• Fiduciary responsibility is a legal obligation to act in another party’s best interests in relationships of trust-commonly, directors acting in the best interests of the company.
• Directors (including founder-directors) often owe fiduciary duties, and in some cases senior employees and founders can also have fiduciary obligations depending on their role and influence.
• Director obligations can come from both general law (including fiduciary principles) and statute (the Corporations Act), and a single set of facts can trigger both.
• Common problem areas include conflicts of interest, related-party deals, misuse of information, taking company opportunities personally, and messy exits where clients or IP are involved.
• Practical risk management steps include documenting decisions, disclosing conflicts early, and having strong governance and operational documents (like a Company Constitution and Shareholders Agreement).
• Clear processes and tailored contracts make it much easier to show decisions were made properly and reduce the chance of disputes escalating.
