Setup a Company in Australia Legal Steps, Costs & Compliance
Setting up a company in Australia (most commonly a proprietary limited company / Pty Ltd) can be a smart move if you want limited liability, clearer ownership structures, and a platform that’s easier to scale, sell, or bring investors into later. But it’s also a legal structure with real compliance obligations, and getting the setup wrong can cause expensive issues later (share disputes, director duty risks, tax problems, contract problems, or even personal liability in some scenarios).
This guide explains how to setup a company in Australia, what it costs to setup a company, and what Queensland business owners should think about before and after registration, written for people who want clarity, not jargon. If you want tailored legal advice (especially where there are multiple shareholders, investor money, vendor finance, or complex contracts), Mark Game and the Aylward Game Solicitors team can help structure it properly from day one.

What does it mean to setup a company in Australia?
When you setup a company in Australia, you create a separate legal entity that can own assets, sign contracts, employ staff, borrow money, and be sued, separately from you personally. This is the main reason many growing businesses move from sole trader or partnership into a company structure.
In Australia, companies are registered on the Australian Companies Register, managed by ASIC.
Who should setup a company?
Common reasons include:
- Limiting personal exposure (limited liability doesn’t remove all risk, but it helps)
- Bringing in shareholders/investors
- Building a business asset you can sell later
- Separating business finances and contracts from personal affairs
- Improving governance and credibility with banks/suppliers
When is a company not the right fit?
A company can be overkill if you’re testing an idea, operating very small, or want minimal compliance. Other structures (sole trader, partnership, trust) may be more suitable depending on tax, asset protection, and risk profile.
Practical tip (Queensland): If you’re signing leases, supply agreements, building contracts, or finance documents in Brisbane, Gold Coast & Sunshine Coast markets, a company can reduce personal risk, but contracts often include personal guarantees, which need legal review.
The building blocks you need before registering a company
ASIC sets out key items you should have ready before registering.
1. Company name (and availability checks)
You can choose a name (e.g., ABC Pty Ltd) or use the ACN as the company name. You should also check:
- Similar company names
- Business name conflicts
- Branding/trademark issues (especially if you’re investing in marketing)
If you plan to trade under a name that’s different from the company name, you’ll likely need a registered business name as well.
2. Addresses (registered office + principal place of business)
You’ll need an Australian address for the registered office. If the company doesn’t occupy the premises, you generally need the occupier’s consent (this is a common compliance miss).

3. Company rules: constitution vs replaceable rules
You can:
- Rely on the replaceable rules in the Corporations Act, or
- Adopt a company constitution, or
- Use a combination.
This choice matters a lot if you have more than one shareholder, future investment plans, or different share rights.
4. Share structure, shareholders, and control
Even in a small company, you should be clear on:
- Who owns what percentage
- Whether shares are equal or different classes exist
- Who controls decisions
- How disputes or exits will be handled
This is where many mates’ rate setups fail later, because no one documents the deal properly.
5. Officeholders: directors (and secretaries if applicable)
ASIC requires company officeholders to be appointed, and directors have serious legal duties.
Director ID requirement: If you plan to become a director, you must apply for a director identification number (director ID) before you’re appointed.
How to setup a company in Australia: step-by-step
Step 1: Decide the company type
Most small businesses choose a proprietary limited company (Pty Ltd), but other types exist (public companies, not-for-profit special purpose companies, etc.).
Step 2: Register online using the Business Registration Service (BRS)
ASIC confirms you can use the Australian Government Business Registration Service (BRS), and ASIC then processes the registration.
Business.gov.au suggests the online process can be fast when everything is ready (often around 15 minutes), and you may receive confirmation within about 2 business days, depending on completeness and payment.
Step 3: Receive confirmation and your key identifiers
Once registered:
- The company appears on the Companies Register
- If you used BRS, you’ll receive an email confirmation with the ACN and certificate of registration
- ASIC sends the corporate key to the registered office address (used for ongoing online management)

Cost to setup a company in Australia
ASIC registration fee
ASIC publishes company registration fees and notes that the fee depends on the company type.
ASIC’s fee tables use internal fee codes and can change, so it’s important to check the current ASIC fee schedule at the time you lodge.
Hidden or overlooked costs
When people search for how much it costs to setup a company, they often forget these common extras:
- Legal advice for constitution + shareholder arrangements (especially if 2+ owners)
- Trade mark checks/registration (if brand is important)
- Accounting setup, bookkeeping, payroll systems
- Ongoing ASIC annual review fee obligations
- Business name registration (if trading name differs)
Legal obligations after you setup a company
Setting up the company is the beginning, not the end.
1. Displaying your company details
ASIC explains that you must display the company name where the company does business and include the company name and ACN on certain documents.
2. Keeping ASIC details up to date
Officeholders must keep company details up to date, maintain records/share registers, and pay required fees (including annual review fees).
3. Director duties under the Corporations Act (high-risk area)
Directors must comply with duties under the Corporations Act 2001 (Cth), including acting with care and diligence and acting in good faith and for proper purposes (and avoiding misuse of position or information).
4. Queensland-specific operational compliance (common triggers)
Even though company registration is federal, Queensland businesses should also think about state-based compliance once trading begins:
- Work Health and Safety: Queensland WHS laws impose a primary duty of care on persons conducting a business or undertaking (PCBU).
- Workers’ compensation: Many Queensland employers need to consider WorkCover arrangements and obligations under Queensland workers’ compensation legislation.
Why Queensland business owners should involve a commercial lawyer early
If your company setup is simple (single director, single shareholder, low risk), you might register without legal help. But many Queensland businesses are not actually simple once you look closer, especially if you have:
- Two or more founders (ownership and exit planning needed)
- Investors or planned capital raising
- High-value contracts or supply chains
- Property transactions or leases
- Disputes are already brewing between stakeholders
- Vendor finance / instalment sale / lease option arrangements (high risk if drafted poorly)

Frequently Asked Questions (FAQs)
1. How to setup a company in Australia?
To setup a company in Australia, you choose a company type (often Pty Ltd), prepare key details (name, addresses, directors, shareholders, rules/constitution), and then register online via the Business Registration Service, which ASIC processes. You’ll receive an ACN and certificate once registered.
2. How much does it cost to setup a company?
The cost to setup a company includes an ASIC registration fee that varies by company type, plus optional costs like legal advice, constitution/shareholder documents, business name registration, and accounting setup. ASIC publishes current fees, and they can change, so confirm before lodging.
3. Do I need a business name if I have a company?
If you trade under a name different to your company’s legal name, you generally need to register a business name with ASIC. If you only use your exact company name, you may not need a separate business name registration. Always check name rules and availability first.
4. What is an ACN, and when do I get it?
An ACN (Australian Company Number) is a unique identifier issued by ASIC when your company is registered. It’s used to identify your company and must appear on certain documents. If you register via BRS, you’ll receive the ACN in the confirmation email.
5. What is a director ID, and when do I apply?
A director ID is a unique number you keep for life. If you plan to become a director, you must apply for a director ID before you’re appointed. You can apply personally through ABRS and in advance. Your accountant or lawyer can’t apply on your behalf.
6. Should I use a constitution or replaceable rules?
Replaceable rules can work for simple companies, but a constitution is often better where there are multiple shareholders, different share rights, or future investment plans. A constitution can tailor decision-making, disputes, exits, and share transfers, issues that templates rarely handle well.
7. How long does it take to setup a company?
If your details are ready, online registration can be quick. Business.gov.au indicates it can take around 15 minutes to complete the BRS process, with confirmation often within about 2 business days, where documents are complete and the fee is paid. Timeframes can vary.
8. What legal obligations apply after company registration?
After registration, officeholders must keep company details up to date, maintain company records and share registers, and pay required ASIC fees, including annual review fees. You must also display the company name and include the ACN on certain company documents.
9. What Queensland laws should new companies think about when hiring?
If you employ staff in Queensland, you must consider WHS duties and workplace safety compliance, as well as workers’ compensation arrangements. Queensland WHS law includes a primary duty of care for PCBUs, and workers’ compensation obligations may apply through WorkCover frameworks.
