Starting a small business in Australia can be an exciting opportunity, but turning an idea into a real business requires planning.
Before you spend money on branding, equipment or advertising, you need to understand your customers, choose an appropriate business structure, complete the right registrations and work out your startup costs.
The good news is that you do not need everything figured out before you begin.
This guide explains how to start a small business in Australia and gives you a practical 90-day plan to help move from an idea to your first customers.
What You Need Before Starting a Small Business in Australia
Before you register your business, have a basic understanding of:
- What product or service you will offer
- Who your target customers are
- What problem you are solving
- What competitors are offering
- How you will make money
- Your expected startup and ongoing costs
- Which business structure may suit you
- Whether you need licences or permits
You do not need a perfect business plan at this stage. The goal is to understand whether your idea is realistic before making a major financial commitment.
Test Your Business Idea Before Spending Money
One of the most useful steps when starting a small business is testing whether customers actually want what you plan to sell.
Start by researching your target market and competitors.
Ask yourself:
- Who is most likely to buy from me?
- What problem does my product or service solve?
- What alternatives already exist?
- How much are competitors charging?
- How will customers find my business?
- What can make my offer different?
You can test demand by talking to potential customers, offering a small trial, creating a simple landing page or taking a limited number of initial orders.
The goal is to learn before you invest heavily.
Choose the Right Business Structure
Your business structure can affect your tax obligations, legal responsibilities, administration and personal liability.
Common structures in Australia include sole trader, partnership, company and trust.
Sole Trader
A sole trader structure is relatively simple to set up and manage. You operate the business personally and generally report business income through your individual tax return.
It may suit some freelancers, contractors and small businesses with straightforward operations.
However, a sole trader generally has unlimited personal liability for business debts and obligations.
Partnership
A partnership involves two or more people running a business together.
Partners generally share income, losses and responsibilities according to their partnership arrangement. A written agreement can help clarify ownership, responsibilities and decision-making.
Company
A company is a separate legal entity from its owners.
A proprietary company is commonly structured as a Pty Ltd business in Australia. Companies have their own registration, reporting and administrative requirements.
Which Structure Is Right for You?
There is no single business structure that works for every business.
Your decision may depend on:
- Business risk and personal liability
- Number of owners
- Expected growth
- Tax considerations
- Administrative requirements
- Plans for investors or partners
If you are unsure, consider getting advice from a qualified accountant or business adviser before registering.
Register Your Business Correctly
Once you have decided to move forward, check which registrations apply to your business.
| Registration | When It May Apply |
| ABN | Many businesses carrying on an enterprise in Australia |
| Business name | When trading under a name different from your own name or registered company name |
| Company registration | If you choose to operate through a company |
| GST registration | Generally when GST turnover reaches the applicable threshold |
| Licences and permits | Depending on your industry, activities and location |
Apply for an ABN
An Australian Business Number (ABN) is an 11-digit number used to identify your business when dealing with government agencies and other businesses.
ABN applications are generally free through the Australian Business Register.
Register a Business Name
If you operate under a name different from your own name or your company’s registered name, you may need to register a business name.
Before choosing a name, check its availability and consider whether it conflicts with an existing trade mark.
Business Name vs Trade Mark
A business name registration does not provide the same protection as a registered trade mark.
If your brand is important to your business, consider checking trade mark availability before investing heavily in branding.
Check GST and Licences
Businesses generally need to register for GST when their GST turnover reaches the applicable threshold, although other circumstances can also affect GST registration.
You should also check whether your business requires specific licences or permits. Requirements can vary depending on your industry, activities and location.
The Australian Business Licence and Information Service (ABLIS) can help you identify relevant requirements.
Understand Your Startup Costs
Your startup costs will depend heavily on the type of business you are starting.
Common expenses can include:
- Business registration
- Website and domain
- Insurance
- Accounting software
- Professional advice
- Equipment
- Marketing
- Stock or inventory
The following examples are illustrative only. Actual costs can vary.
Example Startup Budget for a Sole Trader
| Item | Estimated Cost |
| ABN | $0 |
| Business name, if required | $47 |
| Domain and simple website | $200–$600 |
| Insurance | $400–$1,500 per year |
| Accounting software | $360–$800 per year |
| Accountant setup/advice | $300–$1,000 |
| Illustrative total | About $1,300–$4,000 |
Example Startup Budget for a Pty Ltd Company
| Item | Estimated Cost |
| ASIC company registration | $636 |
| Legal setup and advice | $600–$2,000+ |
| Accountant setup | $300–$1,000+ |
| Business name, if required | $47 |
| Insurance and website | $600–$2,100 |
| Annual review fee | $342 |
| Illustrative first-year total | About $2,500–$6,100+ |
Government fees can change, so check the current fees before registering.
It is also sensible to keep a cash buffer for unexpected expenses and slower sales periods.
Set Up Your Business Finances
Good financial organisation from the beginning can make running a business much easier.
Consider setting up:
- A dedicated business bank account
- Accounting or bookkeeping software
- A system for recording expenses
- A process for sending invoices
- A system for tracking income
- Regular financial reviews
For companies, keeping business and personal finances separate is particularly important.
Even for sole traders, using a separate account for business transactions can make bookkeeping and record keeping easier.
Keep relevant invoices, receipts and financial records according to Australian requirements.
Build the Essentials Before Launch
You do not need an expensive website or complicated technology to start.
Focus on the essentials.
Create a Simple Website
Your website should clearly explain:
- What you offer
- Who you help
- Why customers should choose you
- How customers can contact or buy from you
Set Up Professional Communication
Consider using a business email address based on your domain.
Depending on your business, you may also need social media profiles, online booking, payment processing or customer management software.
Start with the tools you actually need and add more as your business grows.
Launch Small and Get Your First Customers
Your first launch does not need to be complicated.
Focus on getting real customers and learning from their feedback.
You can:
- Contact people in your network
- Ask for referrals
- Publish useful content
- Use social media
- Run a small advertising campaign
- Partner with complementary businesses
- Attend relevant local events
Your first customers can help you understand whether your pricing, offer and customer experience need improvement.
Your 90-Day Small Business Launch Plan
| Timeline | Main Goal | Key Actions |
| Days 1–14 | Validate | Research customers, competitors and demand |
| Days 15–30 | Decide | Choose your structure, business name and basic plan |
| Days 30–45 | Register | Apply for an ABN, register your business name if needed and check licences |
| Days 45–60 | Set Up | Organise banking, accounting, insurance and finances |
| Days 60–75 | Build | Create your website, pricing and basic systems |
| Days 75–90 | Launch | Get your first customers, collect feedback and improve |
This is a guide rather than a strict deadline. Some businesses may need more time for licensing, product development, premises or other requirements.
Common Mistakes to Avoid
Spending Too Much Before Testing Demand
Do not spend your entire budget on branding, equipment or advertising before confirming that customers want your product or service.
Choosing a Structure Without Understanding It
Your structure can affect liability, tax and administration. Understand your options before registering.
Ignoring Licences and Permits
Check the requirements for your industry and location before starting operations.
Mixing Personal and Business Finances
Keeping clear financial records from the beginning can make bookkeeping and tax preparation much easier.
Setting Prices Without Calculating Your Costs
Your prices need to account for direct costs, overheads, taxes, payment fees and the time required to deliver your product or service.
