When Is a Special Resolution Required in Australia?

If you run a company in Australia, there’ll be times when a simple vote of shareholders isn’t enough. Certain big decisions need an extra level of approval called a special resolution.

Knowing when a special resolution is required matters. Get it wrong and you risk invalid decisions, delays with ASIC, and potential disputes among shareholders.

In this guide, we’ll explain what a special resolution is, the key scenarios that require one, how to pass it properly, and common pitfalls to avoid - all in plain English for busy business owners.

What Is A Special Resolution In Australia?

A special resolution is a decision of a company’s members (shareholders) that needs a higher approval threshold than an ordinary resolution.

Under the Corporations Act 2001 (Cth), a special resolution generally requires at least 75% of the votes cast by members entitled to vote on the resolution. The notice of meeting must also state that the resolution is proposed as a special resolution and set out the text of the resolution.

You can pass a special resolution at a members’ meeting (for example, at an Extraordinary General Meeting) or, for proprietary companies, by written circulating resolution in some cases (more on that below). The key is meeting the 75% threshold and following the correct notice and procedural rules.

When Is A Special Resolution Required For Small Companies?

Not every major decision needs a special resolution - but many do. Below are the most common scenarios for Australian small-to-medium companies.

Adopting, Modifying Or Repealing A Company Constitution

Changing your company’s rules is a significant step, so it requires a special resolution. This includes adopting a new constitution, amending an existing one, or replacing it entirely. If you’re formalising your rules, it’s common to put a tailored Company Constitution in place or to use a service to adopt a constitution that suits your business.

Changing Your Company Name Or Type

Changing the company’s name requires a special resolution of members. Converting your company from proprietary to public (or the other way around) also requires member approval by special resolution, plus ASIC filings.

Reducing Share Capital Or Buying Back Shares

Any reduction of share capital must be approved by a special resolution and follow the statutory process (including solvency and fairness considerations). Many types of share buy-backs also require member approval - and some (like selective buy-backs) require a special resolution with restrictions on who can vote. If you’re considering a buy-back, it’s wise to document the terms with a Share Buyback Agreement.

Varying Or Cancelling Class Rights / Issuing Preference Shares

If your company has different classes of shares (for example, ordinary and preference), changing or cancelling the rights attached to a class generally requires a special resolution passed by that class. Issuing a new class of shares with special rights (such as preference shares) will also typically trigger a class approval process. If you’re designing your capital structure, it helps to understand different classes of shares and when class consents are needed.

Providing Financial Assistance For Share Acquisitions

When a company gives financial assistance to someone to buy its shares or shares in its holding company, approval by special resolution is often required (with limits on who can vote). This area is technical - get advice before proceeding.

Voluntary Winding Up, Major Restructures Or Transfers

Starting a members’ voluntary winding up requires a special resolution. Some significant restructures, such as selective reductions of capital or certain transactions contemplated by your constitution, may also require special resolution approval.

Anything Your Constitution Requires

Your constitution can require a special resolution for additional matters beyond the Corporations Act. Common examples include approval for certain large asset sales, loans to directors, or changes to dividend policies. Always check your constitution alongside the Act when planning a major decision.

How Do You Pass A Special Resolution Properly?

Here’s a practical checklist to help you run a compliant process.

1) Confirm The Approval Path

Decide whether you’ll hold a meeting of members (often an Extraordinary General Meeting) or use a circulating written resolution if your company is eligible and the decision is suitable. For urgent matters outside an AGM, many companies convene an EGM - see our guide on Extraordinary General Meetings to plan timing and logistics.

2) Draft Clear Resolution Wording

The notice must state that the resolution is proposed as a special resolution and set out the exact wording. Keep it specific so members know what they’re approving.

3) Give Correct Notice

Members generally need at least 21 days’ notice, unless your constitution allows shorter notice and sufficient members agree. The notice should include the time, date, place (or online meeting details), the special resolution wording, and any explanatory notes.

4) Check Quorum, Voting Rights And Proxies

Confirm who can vote, what constitutes a quorum, and how votes will be counted. For class approvals, invite and count votes only from the relevant class. Ensure proxy forms and deadlines align with your constitution and the Corporations Act.

5) Record Minutes And Outcomes

Keep accurate minutes, record the votes and outcome, and attach a copy of the resolution. If documents are executed following approval, directors can generally sign them on the company’s behalf under section 127 - see the rules for signing documents under section 127.

6) Make Any Required ASIC Filings

Many special resolution actions (e.g. name changes, capital reductions, share buy-backs, constitution changes) require forms or documents to be lodged with ASIC within specific timeframes. Put these lodgements in your implementation plan so the decision takes legal effect without delay.

What’s The Difference Between Ordinary And Special Resolutions?

In simple terms, an ordinary resolution passes with more votes in favour than against (a simple majority of votes cast), while a special resolution needs at least 75% approval and special notice requirements.

Use an ordinary resolution for routine decisions (such as appointing an auditor or approving standard matters at an AGM), and a special resolution for the specific, higher-impact decisions set out in the Corporations Act or your constitution.

How Special Resolutions Interact With Your Governance Documents

Two documents do the heavy lifting in most private companies: the constitution and (if you have one) the Shareholders Agreement.

Your constitution sets out the company’s rules. A well-drafted constitution clarifies voting thresholds, quorum, class rights and decision-making mechanics for big-ticket items. If you’re updating governance, it’s worth reviewing both your constitution and any Shareholders Agreement at the same time to ensure they align.

A Shareholders Agreement can include additional approval rights or vetoes for certain shareholders. While the Corporations Act determines when a special resolution is required, your agreement may add further “reserved matters” that also need enhanced approval before directors can act.

Practically, many major share transactions happen in stages: members approve the transaction by special resolution, then directors or authorised officers execute the documents under the company’s signing rules. For day-to-day contracting authority, section 126 of the Corporations Act is relevant - see our overview of section 126 authority in the context of who can bind the company.

Common Pitfalls (And How To Avoid Them)

Here are the missteps we see most often when small businesses handle special resolutions.

Using An Ordinary Resolution When A Special Resolution Is Required

This can invalidate the decision. Always check the Corporations Act provisions and your constitution before sending a notice.

Incorrect Or Insufficient Notice

If the notice doesn’t say the resolution is “special” and include the exact text, it may be defective. Also check the notice period, content requirements, and delivery method (email vs post vs platform) permitted by your documents.

Forgetting Class Approvals

Where class rights are involved, you may need a special resolution by the affected class in addition to (or instead of) a general members’ resolution. This is common when creating or changing rights attached to shares - particularly relevant if you’re introducing preference shares or other classes. If you plan to restructure your equity, read up on share classes and class rights first.

Skipping Post-Approval Steps

Many decisions require follow-up work: lodging with ASIC, updating the share register, issuing new share certificates, or amending your constitution. Share transactions also need accurate documentation - for example, an off-market transfer should follow the formalities in this off-market share transfers guide.

Not Aligning The Constitution And Shareholders Agreement

Conflicts between your constitution and Shareholders Agreement can create uncertainty about what approval is really needed. If you’re changing decision-making thresholds, update both documents consistently, and consider whether any removal or exit provisions (for example, in complex cases of deadlock or misconduct) interact with member approvals - see the overview on removing a shareholder to understand how these governance tools tie together.

Not Documenting Share Buy-Backs Properly

Even with member approval in hand, a buy-back has steps and timing rules, including notices, solvency requirements and ASIC filings. A clear Share Buyback Agreement helps you implement the decision correctly and avoid compliance gaps.

Practical FAQs For Business Owners

Do All Proprietary Companies Have To Hold A Meeting?

Not always. Many proprietary companies can pass resolutions by circulating written resolution instead of holding a physical or virtual meeting, provided the Corporations Act and your constitution permit it. However, for special resolutions by circulation, check the specific procedural requirements and ensure you still reach the 75% approval threshold (and any additional requirements in your constitution).

Can Directors Pass A Special Resolution?

No. Special resolutions are resolutions of members (shareholders), not the board. Directors can make many operational decisions by board resolution, but when the law or your constitution calls for a member special resolution, shareholders must vote.

Is “Special Notice” The Same As A Special Resolution?

No. “Special notice” is a particular notice requirement for certain member-initiated actions (like removing an auditor). It’s separate from the concept of a special resolution, which is about voting thresholds and how the resolution passes.

What Does 75% Approval Mean In Practice?

It’s 75% of the votes cast by members entitled to vote on the resolution (not 75% of all issued shares), unless your constitution specifies otherwise. Always check how abstentions and excluded voters are treated in your specific scenario (for example, in selective buy-backs or financial assistance cases).

Where Do EGMs Fit In?

If you need to pass a special resolution outside your AGM cycle, you’ll typically call an EGM to put the resolution to members. The same 75% threshold and notice rules apply - plan the agenda, timing and voting mechanics carefully, and use the structure outlined in our EGM guide to keep things on track.

Examples: Typical Special Resolution Scenarios

To make this concrete, here are common decisions a growing Australian company might make - and why they often require a special resolution.

• Rebranding and changing your company name to align with a new product strategy.
• Replacing replaceable rules with a bespoke Company Constitution that fits your investor requirements.
• Introducing preference shares for a seed investor and varying class rights to reflect dividend priority and conversion terms.
• Running a selective buy-back to tidy up the cap table when a co-founder exits, documented with a Share Buyback Agreement and supported by solvency statements.
• Providing permitted financial assistance as part of an internal sale to a key manager (subject to the approval process and voting exclusions).
• Starting a members’ voluntary winding up when the company’s purpose is complete and returning surplus capital to shareholders.

In each case, the substance of the decision is important - but the process is equally important. The right wording, notice, voting and filings make the decision legally effective and far easier to implement.

Implementation Tips That Save Time

Here’s how to make the special resolution process smoother.

• Prepare an explanatory memorandum so members understand the commercial logic and legal effect of the resolution.
• Map out dependent steps - constitution updates, share register changes, class consents, and any ASIC lodgements - in a single timeline.
• Circulate draft documents (for example, deed of variation for constitution changes, buy-back agreements, or share issue terms) ahead of the vote so members approve with full context.
• Plan execution logistics early: after approval, directors can sign follow-on documents according to the section 127 rules for company execution, and contracting authority can be delegated under section 126.

Key Takeaways

• A special resolution generally needs at least 75% of votes cast plus specific notice wording - use it for big-ticket decisions set out in the Corporations Act or your constitution.
• Common triggers include adopting or changing your constitution, changing your company name or type, capital reductions and buy-backs, varying class rights, financial assistance, and voluntary winding up.
• Process matters: draft clear wording, give compliant notice, check quorum and voting rules (including class approvals), record minutes, and lodge required ASIC forms.
• Your governance documents work together. Align your constitution with any Shareholders Agreement and plan follow-on actions like share transfers or buy-backs with proper documentation.
• Avoid pitfalls like using the wrong resolution type, missing class consents, or skipping post-approval steps. Planning the implementation timeline upfront saves cost and time.
• If you’re unsure whether a decision needs a special resolution, it’s best to get tailored guidance before you call the meeting or circulate a resolution.
