Legal Differences Between Small And Large Companies In Australia

Whether you’re running a lean startup or leading a fast-scaling enterprise, Australian company law doesn’t treat every company the same. As your business grows, your legal and reporting obligations often grow with it.

Understanding when a proprietary company is “small” versus “large” under the Corporations Act 2001 (Cth) helps you plan ahead, avoid last‑minute scrambles, and invest in the right systems at the right time.

In this guide, we’ll cover how a company is classified, what actually changes as you scale, and the practical steps you can take now to stay compliant and investor‑ready.

What Counts As A Small Vs Large Proprietary Company?

Most private companies in Australia are proprietary companies. The Corporations Act sets out a size test each financial year that determines whether a proprietary company is “small” or “large.” The classification primarily drives your financial reporting and audit obligations.

The Size Test (And The Current Thresholds)

A proprietary company is “large” for a financial year if it meets at least two of these thresholds on a consolidated basis:

• Consolidated revenue of $50 million or more
• Consolidated gross assets of $25 million or more
• 100 or more employees (headcount, not full-time equivalents)

If a proprietary company does not meet at least two of the thresholds above, it is a “small” proprietary company for that financial year.

Important details to keep in mind:

• The test applies on a consolidated basis (so include subsidiaries where relevant).
• “Employees” means people employed by the company or the consolidated group (it’s a headcount test, not an FTE calculation).
• The thresholds apply per financial year, so you should reassess your status each year as circumstances change.

Foreign-Controlled Small Proprietary Companies

Even if you’re “small,” your reporting obligations can change if you’re foreign-controlled. In many cases, foreign‑controlled small proprietary companies must prepare and lodge audited financial reports with ASIC unless specific relief applies (for example, being consolidated into an ultimate Australian parent’s lodged financials or relying on an ASIC relief instrument). If you’re in this category, it’s worth getting advice early on to confirm your position and timelines.

Public Companies Operate Under Different Rules

Public companies sit in their own category with additional requirements such as annual general meetings (AGMs), a company secretary, and continuous disclosure if listed. Many governance obligations that apply to “large” proprietary companies also apply to public companies by default.

Corporate Governance: Boards, Meetings And Policies

Director duties under the Corporations Act apply to companies of all sizes. However, governance tends to become more formal as your company grows and stakeholders increase.

Board Composition And Australian Residency

Proprietary companies can have a single director, provided they meet Australian residency rules. Public companies need at least three directors (two must ordinarily reside in Australia) and at least one company secretary. For all companies, you’ll need to satisfy the Australian resident director requirements for your structure.

AGMs, Secretaries And Company Records

Public companies must hold an AGM within five months after the end of the financial year and maintain additional registers and disclosures. Proprietary companies usually aren’t required to hold an AGM unless the constitution or shareholders require it, but you still need solid board processes, timely resolutions, and accurate minutes.

Public companies must have at least one company secretary, and at least one secretary must be ordinarily resident in Australia. Many growing proprietary companies also appoint a company secretary as a practical step to formalise governance and streamline compliance.

Constitution And Shareholder Arrangements

Small companies can rely on replaceable rules, but many founders adopt a tailored Company Constitution to clarify decision‑making, share issues, and signing rules.

If there are multiple owners, a Shareholders Agreement is close to essential. It sets out voting rights, exits, pre‑emptive rights, deadlock mechanisms, and how new capital is raised. As the cap table expands, investors will expect both documents to be in place and robust.

Whistleblowing And Other Corporate Policies

All companies must comply with the whistleblower protections in the Corporations Act. In addition, public companies and large proprietary companies must have a documented, made‑available Whistleblower Policy.

As you scale, other policies become important too-for example, delegations of authority, anti‑bribery and corruption, securities trading (for listed entities), and information security policies. These support consistent decision‑making and are commonly requested during investor or customer due diligence.

Financial Reporting, Audits And Other Size-Based Regimes

This is where the small vs large distinction really matters. The rules below are high‑level; the specifics can vary based on your structure and ownership (including foreign control), so plan ahead and check your exact position each year.

Small Proprietary Companies

• Generally do not have to prepare or lodge audited financial reports with ASIC unless directed by shareholders holding at least 5% of votes or by ASIC.
• Must still keep adequate financial records to enable the preparation and audit of financial statements if required.
• Foreign‑controlled small proprietary companies often have lodgement and audit obligations unless specific relief applies-confirm early to avoid surprises.

Large Proprietary Companies

• Must prepare a financial report and a directors’ report each financial year.
• Financial reports must usually be audited.
• Must lodge the audited financial report, directors’ report, and auditor’s report with ASIC within prescribed timeframes.

If you expect to become “large,” don’t wait until year‑end to get audit‑ready. Audits require consistent accounting policies, strong internal controls, reliable reconciliations, and timely documentation across the year-not a last‑minute tidy‑up.

Other Size-Based Reporting Regimes

Certain federal schemes also turn on turnover or income thresholds:

• Modern Slavery Statements are required if consolidated revenue is $100 million or more.
• The Payment Times Reporting Scheme applies to entities with total annual income over $100 million.
• Significant Global Entity (SGE) rules and country‑by‑country reporting apply to very large multinational groups.

These regimes bring additional disclosure and governance expectations (and potential penalties), so factor them into your planning if you’re approaching the thresholds.

Fundraising, Ownership And Share Mechanics

How you raise capital-and who you can offer shares to-differs by company type and stage.

Proprietary Vs Public Fundraising

Proprietary companies can’t raise funds from the public in the same way a public company can. Offers are typically limited to private placements and specific exemptions.

Many early‑stage companies rely on the “small scale offerings” and other carve‑outs in section 708 of the Corporations Act. These allow offers to certain investors (e.g. sophisticated or professional investors) without a full prospectus, subject to strict limits and conditions.

Public companies can make public offers with a prospectus or other disclosure document and are subject to stricter disclosure and governance rules (especially if listed).

Employee Equity (Works At Any Size)

Employee equity is now commonplace for startups and growth companies. An Employee Share Option Plan (ESOP) sets clear rules for grants, vesting, performance conditions and exits. As you scale, investors and acquirers will scrutinise your equity plan terms and cap table hygiene.

Share Transfers And Signing Authority

As ownership expands, you’ll deal more often with share issues, transfers and contract execution. Understanding authority under section 126 (agents with company authority) versus section 127 (execution by directors/secretary) helps reduce execution risk and supports enforceable contracts-especially when counterparties ask for specific signing formats.

Employment, Privacy And Other Compliance That Scales With Size

Workplace and privacy laws apply across the board, but some obligations change depending on headcount or turnover.

Fair Work: Small Business Vs Larger Employers

All employers must comply with the Fair Work Act and applicable awards. However, a few key differences turn on your size:

• Redundancy pay generally isn’t required for a “small business employer” (fewer than 15 employees), subject to specific rules.
• The Small Business Fair Dismissal Code applies to unfair dismissal claims involving small business employers.
• Larger businesses typically have more complex consultation obligations for major workplace change and are more likely to engage in enterprise bargaining.

As you grow, formalising HR processes becomes essential. That usually includes written Employment Contracts, a clear performance framework, and a suite of workplace policies to manage risk and maintain consistency.

Privacy And Data Protection

The Privacy Act 1988 (Cth) generally applies to “APP entities,” which typically include businesses with $3 million or more in annual turnover (plus several important exceptions that can capture smaller businesses, such as health service providers or those trading in personal information).

If you’re an APP entity-or working with customers who require it-you’ll need a compliant Privacy Policy, data breach response processes, and robust information security practices. Larger enterprise customers will often audit these controls during procurement and due diligence.

Consumer Law And Standard-Form Contracts

The Australian Consumer Law (ACL) applies to all businesses. Recent reforms strengthened the unfair contract terms regime, with significant penalties for breaches. As you scale, make sure your customer terms, supplier contracts and marketing practices reflect ACL requirements and the realities of larger, more complex deals. If you’re selling online, consider clear website or platform terms alongside your ACL compliance obligations.

Work Health And Safety (WHS) And Insurance

WHS laws apply regardless of size, but larger operations face higher expectations around risk assessments, training, contractor management, and incident reporting. Your insurance program (e.g., public liability, professional indemnity, cyber) should also evolve with your contract values and operational risk profile.

Planning To Scale From Small To Large: Practical Steps

If you expect to meet the “large” thresholds in the next 12–24 months, phasing in systems now will save stress later and make audits, financing rounds and big‑customer deals smoother.

1) Build Audit‑Ready Finance Processes

• Adopt monthly closes with reconciliations and documented accounting policies.
• Introduce segregation of duties and a clear delegations of authority matrix for spend approvals.
• Stand up a central contract repository and revenue recognition tracking aligned to your policies.

2) Upgrade Governance And Board Practices

• Consider independent advisors or directors as your needs evolve.
• Move board packs to a regular cadence with KPIs, risk dashboards and compliance reporting.
• Refresh your constitution and shareholder arrangements to support future rounds or exits-many growing teams revisit their Shareholders Agreement to align on decision‑making and transfer rights.

3) Strengthen Legal Ops And Contract Execution

• Roll out standard templates and negotiation playbooks for sales and procurement.
• Clarify authority and signature blocks, including when to rely on section 126 versus formal section 127 execution.
• Set up a simple intake workflow so legal, finance and sales are aligned on approvals and risk.

4) Ready Your Cap Table And Equity

• Clean up historical grants, ensure consents are captured, and confirm vesting is documented.
• Align your ESOP with investor expectations using a clear Employee Share Option Plan.
• Plan capital raises under the relevant exemptions in section 708, or consider whether transitioning to a public company is appropriate for your goals.

5) People, Privacy And Security

• Formalise HR policies, performance management and regular training.
• Implement a Whistleblower Policy if you will be a large proprietary or public company.
• Ensure your data handling and Privacy Policy meet APP requirements and pass customer audits.

Key Takeaways

• “Small” vs “large” proprietary company status turns on consolidated revenue, assets and employee headcount (not FTEs); you’re “large” if you meet at least two thresholds.
• Large proprietary companies must prepare, audit and lodge financial reports with ASIC; small proprietary companies generally don’t-though shareholder or ASIC directions (and foreign control) can change this.
• Governance becomes more formal as you grow: think board processes, AGMs and a resident company secretary for public companies, and a mandatory Whistleblower Policy for large proprietary and public companies.
• Proprietary companies can’t publicly raise capital; early‑stage raises often rely on exemptions such as those in section 708, while public companies can make public offers with disclosure.
• Employment, privacy and consumer law apply at any size, but thresholds matter-for example, redundancy rules for small business employers and APP entity status for privacy.
• Core documents like a Company Constitution, Shareholders Agreement, Employment Contracts and a Privacy Policy support compliance and smoother growth.
• If you expect to become “large,” invest early in audit‑ready finance, governance, legal operations and data security so you’re ready when the thresholds are met.
