Are you looking for a clear, step-by-step guide on how to start a small business in Australia?
Here at Australian Business Magazine, we’ve spent years covering founders, startups, and small business success stories right across the country. We’ve sat down with many entrepreneurs throughout Melbourne, Sydney, Brisbane, and beyond, so we know what the setup process actually looks like on the ground.
In this guide, we’ll walk you through everything from finding your business idea and choosing the right structure to registrations, tax, cash flow, insurance, and grants. By the end, you’ll have a clear picture of exactly what to do and in what order.
Let’s get into it.
How Do You Come Up with a Solid Business Idea?
Start by looking at your frustrations, your strongest skills, and the problems people in your circle keep asking you to solve. Those three things together are usually where the best concepts hide.
Here’s how to narrow those down:
Look at the Problems You Already Solved
Most people overlook their best business idea because it feels too obvious or too close to home. But the thing is, your everyday skills and personal frustrations are often exactly what other people will pay to have solved.
Say you’re great at bookkeeping and your friends keep asking you to sort out their finances. That’s a business idea staring you in the face.
Research What People Are Paying For
Researching real spending behaviour saves you from building something nobody wants to buy. So browse platforms like Etsy, Amazon, and local Australian Facebook groups to spot what customers are already paying for.
Then check Google Trends with an Australian filter to see whether interest in your concept is growing or fading. If something shows consistent demand over 12 months, you should seriously consider building around it.
Check if the Market Has Room for You
A crowded market isn’t always a dealbreaker. To find your opening, look at existing operations in your space and ask honestly whether they’re actually serving their customers well. If there’s a gap, a specific niche, or an underserved location, you have a real opportunity to step in.
Pro Tip: Talk to at least 10 potential customers before you commit. Real conversations will surface objections, pricing expectations, and product gaps that no keyword tool can show you.
Once you’ve landed on a solid idea, the next step most people rush or skip entirely is putting together a business plan.
Do You Need a Business Plan Before You Start?
Yes, even a simple one-page plan gives you a proper direction and helps you secure funding faster.
You might be thinking a plan needs to be a 40-page document. In reality, a clear summary of your business goals, target audience, start-up costs, and marketing plan is enough to get moving.
Beyond these basics, lenders and investors in Australia will almost always want to see a plan before approving any funding. So think of it less as a formality and more as your personal roadmap. It also helps you spot gaps in your business skills early.
Treat it as a living document, too. As your business grows and your target market shifts, your plan should change with it. After all, what you start on day one rarely looks the same six months in.
Which Business Structure Should You Choose?
It depends on how much personal liability you’re comfortable with, how many people are involved, and your long-term goals.
Getting this wrong early on can cost thousands to fix later, and we’ve covered businesses across Sydney and Melbourne that learned that the hard way. So get professional advice early and lock in the right choice. You have four options to choose from:
1. Sole Trader
Starting as a sole trader keeps your setup costs low and gets you trading legally with minimal paperwork. The catch, though, is that you and the business are treated as one legal entity. So if the business takes on debt or gets sued, your personal assets are on the line (which explains why so many founders outgrow this structure quickly).
2. Partnership
If you want to share the workload and costs of starting a business, a partnership is worth considering seriously. In this structure, two or more people split the profits, losses, and legal responsibilities between them.
Worth Noting: A written partnership agreement between all parties, with clear terms around roles, finances, and exit conditions, keeps everyone protected from the start. Without one, a falling-out between partners can derail the whole operation.
3. Company (Pty Ltd)
Unlike a sole trader, a company is a separate legal entity, which means the business can take on debt, enter into contracts, and be sued independently of you. It’s more complex to run, with ongoing reporting obligations, but for high-growth ventures it’s often the right call.
The main things to sort out before you register include:
- Director ID Requirements: Every company director in Australia must obtain a Director ID through the Australian Business Registry Services. It’s free, and you apply online. However, you need to do it before your company gets registered.
- ASIC Registration and Annual Fees: For most proprietary companies, the registration fee sits at either $503 or $611, depending on the company type. On top of that, you’ll pay an ongoing annual review fee of $329 per year for a standard proprietary company, or $67 for a special purpose proprietary company.
And that’s just the registration side. Between the Director ID, ASIC fees, and the added compliance workload, a company structure demands more from you upfront than any other option. That’s why you should get your numbers sorted first.
4. Trust
A trustee, either a person or a company, holds and runs the business on behalf of the trust’s beneficiaries. This arrangement can offer real tax and asset protection advantages, particularly for family businesses or those managing significant assets.
We recommend getting professional advice from an accountant or solicitor before going down this path. It is one of the more involved structures to set up, and the ongoing legal obligations aren’t something to handle alone.
How Do You Register Your Business in Australia?
Registering a business in Australia covers a few steps, and the bulk of it happens online. Let’s walk through what you need to get done:
Get Your Australian Business Number (ABN)
Your ABN is the foundation of your business identity in Australia, and applying for one is completely free.
Simply head to the Australian Business Register, and most applications get processed the same day. You’ll want to do this first, because almost everything else, from opening a bank account to lodging your name, requires an ABN to proceed.
When you operate without one, other businesses must legally withhold 47% tax from any payments they make to you. That’s nearly half your income gone before it even hits your account.
Register Your Business Name with ASIC
If you trade under any name other than your own, you must lodge it with ASIC. Since your business name is essentially how customers find you, choose one that’s clear, memorable, and easy to search online.
To get started, check availability on the ASIC register first. Your preferred name may already be taken. Once you’ve confirmed it’s available, registration costs $45 for one year or $104 for three years.
Keep in mind that a listed name doesn’t provide exclusive rights to use it as a trademark. For that, you’d need to file separately with IP Australia to protect your intellectual property.
How Much Does It Cost to Start a Small Business in Australia?
Most operations in Australia spend somewhere between $5,000 and $20,000 to get off the ground, depending on the business type.
That said, if you want to start a business in Australia from home, the start-up costs can sit well under $5,000. A retail shop or café, on the other hand, can push past $50,000 to $100,000 once fit-out, equipment, and stock are factored in.
The table below gives a quick breakdown of the common registration and setup costs:
| Item | Cost |
| ABN Registration | Free |
| Business Name (1 year) | $45 |
| Business Name (3 years) | $104 |
| Company Registration (Pty Ltd) | $503 or $611 |
| Annual ASIC Review Fee | $329 (standard proprietary) |
| Public Liability Insurance | $500 to $2,000 per year |
| Domain Name (.com.au) | $10 to $50 per year |
Beyond registration, the expenses that catch many new starters off guard are the ongoing ones. Think accounting software, marketing, and insurance. These costs don’t show up in any registration checklist but add up steadily over the first few months.
Budget Tip: Map out at least three to six months of expected operating expenses alongside your initial investment. That buffer gives your business a genuine runway to find its feet before the pressure of consistent revenue kicks in.
What Licences and Permits Do You Need?
The licences you need depend entirely on your industry and location, so there’s no single answer for every business. A food chain in Melbourne, for example, faces completely different requirements from a building contractor in Perth (same country, very different paperwork).
That’s why you should use the free ABLIS tool to pull up a personalised list of every licence and permit your business type requires. It’s a government resource that takes less than five minutes to use and saves a lot of guesswork.
You should check your state or territory government website too. Some industries carry additional local obligations that ABLIS won’t always capture. And frankly, those are the ones that trip people up most often. Trading without the correct licences puts you at risk of fines, forced closure, or personal liability for any incidents, so ensure compliance before you open your doors rather than after.
With licences ticked off, the question worth asking now is what happens if something goes wrong once you’re actually trading.
Do You Need Business Insurance?
Yes, and the type you need depends on your industry, whether you have staff, and the nature of your daily operations. Most businesses need at least one form of cover from day one, and public liability insurance is the most common starting point.
It protects the business if a customer or third party gets injured or suffers property damage, with costs typically ranging from $500 to $2,000 annually. For service-based businesses that provide advice or professional services of any kind, professional indemnity cover is worth including in your policy mix.
And if you bring on staff, the obligation goes further. Every Australian state and territory requires workers’ compensation insurance the moment you take on your first employee. The premium varies depending on your industry and payroll size, but it’s not optional.
Some business types may also need product liability, business interruption, or specific health and safety cover depending on what the work involves. A good insurance broker can help identify the right cover mix without overselling policies you don’t actually need.
What Do You Need to Know About Tax and the Australian Taxation Office?
The Australian Taxation Office manages everything from income tax to business activity statements, so knowing their requirements before you start trading is non-negotiable. (Tax issues are among the top reasons new operations struggle in year one.)
Two registrations most small businesses need to address are GST and PAYG withholding.
GST Registration
GST registration becomes compulsory once your annual turnover hits $75,000. If your customers are other businesses that claim GST credits, register voluntarily. It makes invoicing cleaner and more professional straight away.
Once registered, you must charge 10% GST on all taxable sales and lodge a Business Activity Statement with the ATO regularly. For most small businesses, BAS gets lodged quarterly. So set calendar reminders for each deadline now, because missing a lodgement date can trigger fines that eat directly into your margins.
PAYG Withholding
After your first employee comes on board, registering for PAYG withholding with the Australian Taxation Office is a legal requirement. Simply put, this means deducting tax from employee wages each pay cycle and sending those amounts to the ATO on their behalf.
You report and pay withheld amounts either monthly or quarterly, depending on your total withholding volume. Plus, keeping clean payroll records from day one makes this process significantly easier when tax return time comes around.
Note: Failing to lodge when required is a compliance breach that attracts serious penalties.
But staying compliant is only half the battle. What happens to your cash flow when the income doesn’t match the outgoings?
How Do You Manage Cash Flow as a New Business?
More Australian companies fail from poor cash flow management than from bad ideas. Through our reporting on small business struggles across the country, it comes up time and again as the breaking point.
A few simple habits keep things under control from the start:
- Track Every Dollar: Start with accounting software like Xero or MYOB to record every income and expense transaction from your very first sale. Both tools handle invoicing, payroll, and BAS preparation in one place, which saves hours of admin each month.
- Separate Your Finances: Mixing personal and business money creates bookkeeping headaches and complicates tax time significantly (nobody wants that, right?). That’s why you should open a dedicated bank account straight away.
- Plan for Slow Months Early: Businesses that survive plan for slow periods well in advance rather than scrambling when they arrive. As we covered in the costs section, budget for at least 3 to 6 months of operating expenses, so a quiet month doesn’t threaten the whole operation.
Plus, a simple cash flow forecast in a spreadsheet, updated monthly, helps spot problems before they become serious. And if numbers aren’t your strong suit, an accountant can set this up in a single session.
When Should You Hire Employees?
Hiring too early drains cash, and waiting too long caps growth. In conversations with Brisbane and Perth business owners we’ve profiled, getting this timing wrong was one of the most common early mistakes.
A safe bet is to hire when the work consistently exceeds what one person can handle, instead of when you think it might. There’s a lot to get right on the legal side, too, and we’ll cover the two biggest obligations in this section.
Understanding Fair Work Obligations
You need a clear understanding of your obligations under the Fair Work Act prior to hiring anyone in Australia. This applies to every single employee, regardless of business size, and covers things like:
- Minimum wages
- Leave entitlements
- Dismissal rules
- Workplace health and safety standards
So head to fairwork.gov.au to confirm the correct award wage and conditions for your specific industry before making any offers. Different industries operate under different awards, and paying the wrong rate, even accidentally, can trigger back-payment claims.
Legal Tip: Draft a written employment contract for every hire. Verbal agreements create disputes and offer little legal protection if things go sideways.
Superannuation and Your Responsibilities
After sorting Fair Work obligations, superannuation is the next compliance piece to get right. Employers must pay 12% super on top of ordinary wages for each eligible employee, and those contributions go directly into the employee’s nominated fund each quarter.
From there, treat super deadlines with the same urgency as taxes. Late or missed contributions attract ATO penalties and interest charges that compound quickly (we’ve spoken to enough business owners who learned this one the expensive way).
Plus, register for Single Touch Payroll through the ATO to report wages and super every time payroll runs. It keeps everything transparent and saves a mountain of paperwork at year’s end.
Are There Grants Available for Small Businesses in Australia?
Yes, but eligibility depends on your industry and which state or territory you’re operating from. Not every grant suits every business, so it pays to do your research before applying.
The business.gov.au portal is the best starting point for federal grants, loans, and support programs. The listings get updated regularly, so check back often for the latest updates.
If you want to start a small online business in Australia, you should explore the Digital Solutions Program. It’s a government-backed initiative offering subsidised digital advice and training specifically for entreprenuers.
State-based funding is a separate pool entirely. Queensland, Victoria, and NSW each run their own small business support initiatives, and the eligibility criteria differ from federal programs. The smartest move is to bookmark your state government’s small business page alongside the federal portal.
You might be thinking grants are too competitive or too complicated to bother with. In reality, many go unclaimed simply because owners don’t know they exist. Most require a completed business plan and a registered ABN, so if those are already sorted, you’re closer to being eligible than you think.
Small Business Setup Checklist
Now that you know what’s involved in starting a business in Australia, use this checklist to make sure nothing slips through the cracks during setup.
| Step | Task | Done? |
| 1 | Validate your business idea | ☐ |
| 2 | Write your business plan | ☐ |
| 3 | Choose your business structure | ☐ |
| 4 | Register your ABN at abr.gov.au | ☐ |
| 5 | List your business name with ASIC | ☐ |
| 6 | Check licences and permits via ABLIS | ☐ |
| 7 | Set up business insurance | ☐ |
| 8 | Lodge for GST if turnover exceeds $75,000 | ☐ |

| 10 | Open a dedicated business bank account | ☐ |
| 11 | Set up accounting software | ☐ |
| 12 | Research available grants at business.gov.au | ☐ |
We recommend working through each item in order, since some steps, like getting your Australian Business Number (ABN), must be done before others can follow.
Every box ticked means one less thing that can catch you off guard once trading begins. And if you’re still working through a few of these, that’s completely fine. Business starting is a process, and what matters is that each step gets done properly rather than rushed.
Your Next Step Starts Here
Starting a new business in Australia is one of the most important decisions you’ll ever make for your financial future, but the setup phase is where many people lose momentum.
The reason comes down to information overload. There are too many sources with too little clarity, and nobody hands new starters a clear map. That’s exactly what this guide was built to do.
So take that checklist and work through it section by section. The businesses that succeed long-term are the ones that built solid foundations and kept their own business on the right side of the law from day one.

FAQs
Here are some of the most common questions we hear from people starting out:
Can I Register a Business Under My Own Name in Australia?
Yes. If you trade under your own name, you don’t need to lodge business registrations with ASIC.
That said, setting up a separate business name gives your brand more credibility and makes it easier for customers to find you. It’s one of the key things worth sorting early, even if it’s not legally required.
What Tax Deductions Can I Claim as a New Business Owner?
You can claim most expenses directly tied to earning income as tax deductions. This includes accounting fees, marketing costs, relevant software subscriptions, and home office expenses if you run the business from home. The ATO website gives free access to a full breakdown of what qualifies, so check it before your first tax return.
Can I Buy an Existing Business Instead of Starting from Scratch?
Yes, and for some people it’s a faster path to becoming your own boss. Purchasing an existing business means inheriting customers, revenue, and processes that are already running. You’ll still need to review the structure, understand your tax obligations, and check whether the new ownership requires you to provide insurance cover for staff.
