Becoming a company director in Australia, eligibility, appointment and duties

Appointing a director is one of the most consequential decisions a small business can make. The person you put on the board gains legal power over the company's money, contracts and strategy, and the law holds them personally accountable for how they exercise that power. Before anyone can be appointed, both the individual and the company must satisfy a set of legal requirements in the Corporations Act 2001 (Cth) (the Act). This article sets out who must meet those requirements, the thresholds a candidate must clear before appointment, what the company must do within 28 days of an appointment, and the duties and penalties that come with the role.

Who must meet the criteria

The eligibility rules in the Act apply to anyone appointed as a director of a company registered in Australia, whether it is a proprietary company (Pty Ltd) or a public company. The practical effect of the rules:

Proprietary companies: must have at least one director, and that director must ordinarily reside in Australia.
Public companies: must have at least three directors, at least two of whom ordinarily reside in Australia.
Alternate directors: count towards those minimums only while they are actually acting in the role.
Corporate trustees: a director of a company that acts as trustee, for example of a self-managed super fund, is a director of that company and must meet the same criteria.
Shadow and de facto directors: under s 9AC of the Act, a person who is not formally appointed but acts in the position of a director, or whose instructions the board is accustomed to follow, is treated as a director. The criteria and the duties can therefore catch people who never signed a consent form.

The director identification number requirement extends even further, to directors of registered Australian bodies, registered foreign companies and Aboriginal and Torres Strait Islander corporations.

Under s 201B of the Act, only an individual who is at least 18 can be appointed as a director. The role is reserved for natural persons: a company cannot appoint another company or a trust as a director of an ordinary company.

Before the appointment takes effect, the incoming director must give the company a signed consent to act (s 201D). The company must keep that consent with its records. Failing to obtain the signed consent is a strict liability offence for the company, which means it does not matter whether the company intended to breach the requirement. In practice, the consent should be signed and filed at the same time as the minutes of the meeting that resolves the appointment.

Threshold two: the director identification number

Since April 2022, every director must hold a director identification number (the director ID) before they can be appointed. The Act requires an eligible officer to have a director ID (s 1272C), and applying for one is a personal step: no one, including an accountant, tax agent or lawyer, can apply on your behalf. The practical details of the requirement are:

Where to apply: online through the Australian Business Registry Services (ABRS) using a Digital ID such as myID.
When to apply: before the appointment takes effect. You can apply up to 12 months before you expect to be appointed.
How many you need: one, for life, even if you sit on multiple boards.
Who does what: the ABRS issues and administers director IDs, and ASIC enforces the obligations.

There is a change coming. From 1 July 2027, companies will need to provide their directors' director IDs to ASIC as part of company reporting. The practical advice now is to make sure every current director has applied, so the company is not scrambling to collect numbers later.

Threshold three: not disqualified from managing corporations

A person cannot be appointed if they are disqualified from managing corporations under Part 2D.6 of the Act. Disqualification is automatic in several situations (s 206B):

Convictions: a conviction on indictment for an offence concerning decisions that affect a corporation's business or financial standing, or a conviction for an offence involving dishonesty punishable by at least three months' imprisonment, carries automatic disqualification for five years.
Bankruptcy: an undischarged bankrupt is automatically disqualified.
Personal insolvency agreement: a person who has signed a personal insolvency agreement under the Bankruptcy Act 1966 (Cth) and has not fully complied with its terms is automatically disqualified.
Court and ASIC orders: a court or ASIC can also disqualify a person for a set period, for example after a breach of the Act.

A disqualified person commits an offence if they manage a corporation (s 206A), and a person who is disqualified can only be appointed with permission from ASIC or leave from a court (s 201B). Before appointing anyone, it is worth checking the ASIC registers for a disqualification, banning order or bankruptcy that would make the appointment unlawful.

Residency and board-size rules

Section 201A of the Act sets the minimum size of every board and where directors must live:

Proprietary company: at least one director, and that director must ordinarily reside in Australia. Where a proprietary company has more than one director, at least one must ordinarily reside in Australia.
Public company: at least three directors (not counting alternate directors), and at least two must ordinarily reside in Australia.
Edge case: a proprietary company with crowd-sourced funding shareholders must have at least two directors, with a majority ordinarily residing in Australia.

These are ongoing requirements, not one-off checks at appointment. If a company's only resident director moves overseas, the company needs to fix the position, for example by appointing another resident director.

What the company must do when a director is appointed

The appointment itself usually follows the company's constitution or, where there is no constitution, the replaceable rules in the Act. The members appoint directors by ordinary resolution at a general meeting, or the existing directors fill a casual vacancy where the rules allow it. A shareholders agreement may add further steps, such as a right for a particular shareholder to nominate a director.

Once the appointment is made, two things must happen:

Keep the consent: the signed consent (s 201D) stays with the company's records.
Notify ASIC: the company must lodge a notice of the director's personal details with ASIC within 28 days of the appointment (s 205B). The lodgement is done online through ASIC's services.

The 28-day window starts on the day of appointment, not the day the paperwork is signed. It is common for companies to miss the deadline when the appointment is agreed informally and the resolution is documented later.

The duties that come with the role

Once appointed, a director takes on the duties in Part 2D.1 of the Act, whether or not they are paid and regardless of what the company's constitution says:

Care and diligence (s 180): exercise powers and discharge duties with the degree of care and diligence a reasonable person would show in the same position. A director who makes a business judgment in good faith, after informing themselves and with no material personal interest, is protected by the business judgment rule.
Good faith and proper purpose (s 181): act in good faith in the best interests of the company and for proper purposes.
Use of position (s 182): not use their position to gain an advantage for themselves or someone else, or to cause detriment to the company.
Use of information (s 183): not improperly use information obtained through the role to gain an advantage or cause detriment to the company.
Insolvent trading (s 588G): not allow the company to incur a debt when it is insolvent, or when there are reasonable grounds to suspect that it is.

The same duties apply to shadow and de facto directors under s 9AC, so an influential founder or adviser who effectively runs the board can be liable even without a formal appointment.

The cost of getting it wrong

The penalties attached to these requirements are significant, and ASIC actively enforces them:

Director ID: failing to hold or apply for a director ID when required is both a strict liability offence and a civil penalty provision. The maximum civil penalty for an individual is 5,000 penalty units, currently $1.65 million, or three times any benefit gained (s 1317G). Applying for multiple director IDs or misrepresenting a director ID is a criminal offence.
Duties: breaching the civil duties can attract a pecuniary penalty of up to 5,000 penalty units for an individual, currently about $1.65 million, or three times the benefit gained, along with compensation orders and disqualification. The criminal versions of the duties (s 184) carry fines and imprisonment. Insolvent trading can be pursued as a civil penalty, as a compensation claim by a liquidator, and as a criminal offence where dishonesty is involved.
Company obligations: the company commits a strict liability offence if it fails to obtain a signed consent (s 201D), and faces penalties for late or missing ASIC lodgements (s 205B).

Penalty units are indexed, so the dollar figures above rise over time. What matters for a director is that the exposure is personal: the company's insurance and constitution cannot fully shield an individual from these consequences.

Compliance checklist

Before the appointment takes effect, work through this list:

The incoming director applies for their director ID, well before the appointment date.
Someone checks the ASIC registers to confirm the candidate is not disqualified, bankrupt or subject to a banning order.
The signed consent is obtained before the appointment and filed with the company records.
The appointment follows the constitution, the replaceable rules and any shareholders agreement.
The board still meets the residency and minimum-number requirements after the appointment.
A notice of the appointment is lodged with ASIC within 28 days.
The incoming director is briefed on their duties under Part 2D.1 and s 588G.

When a lawyer should be involved

A corporate lawyer can handle the parts of an appointment that carry the most risk:

reviewing the constitution and shareholders agreement to confirm who can appoint directors and how;
checking a candidate's disqualification status and advising on the consequences of an invalid appointment;
drafting the consent to act, the board or shareholder minutes and the ASIC lodgement;
advising a new director on their duties, including the insolvent trading obligation, before they sign anything;
assessing whether anyone who is not formally appointed is exposed as a shadow or de facto director.

Most appointments are straightforward, but the cost of an invalid appointment, a missed lodgement or a breach of duty is out of all proportion to the effort of getting the paperwork right with advice.

The timing trap in every appointment

Two deadlines decide whether an appointment is clean: the director ID must be in place before the appointment takes effect, and the ASIC lodgement is due within 28 days after it. The step most often missed is the director ID, because people assume the company or an adviser arranges it. It cannot: only the individual can apply, and applying is free and takes minutes online. If you are about to become a director, apply for your director ID before you sign the consent, and ask whoever runs the company to diarise the 28-day lodgement on the day of the appointment. Getting those two dates right keeps the appointment valid, the registers accurate and the new director on the right side of the personal penalties that attach to the role.
