How to Start an Online Business in Australia (2026)

To start an online business in Australia, pick a business model you can run around your current commitments, choose a structure (most solo founders start as a sole trader), apply for a free ABN, register a business name if you won't trade under your own name, and open a separate bank account. Then choose where you'll sell, list your first products or services, and learn from what sells. You only need to register for GST once your GST turnover reaches A$75,000.

The paperwork is the easy part and takes an afternoon. What decides whether the business survives past month three is the model you choose and how much of your week it eats. This guide covers both: the registrations and their real costs, the main online business models side by side, the eBay Australia rules that shape a reselling store's costs, and a 30-day start plan.

How to start an online business in Australia: the core steps

Every credible route follows the same backbone. Here is the version you can act on this week.

1. Check demand before you spend. Look at what already sells, not what you wish would sell. For products, that means sold listings on the marketplace you plan to use. For services, it means people already paying for the thing you offer.
2. Pick a business model. Services, digital products, content, or selling physical products. Each has a different cost, skill and time profile, compared below.
3. Choose a structure. A sole trader is the simplest and cheapest to set up, and it is where most solo founders start. A company adds cost and paperwork in exchange for a separate legal entity. If you're unsure, a short session with an accountant is money well spent.
4. Apply for an ABN. It's free through the Australian Business Register, and you need one to register a business name or register for GST.
5. Register a business name if you need one. A sole trader trading under their own first name and surname doesn't need to. Anything else, like "Coastal Home Goods", does.
6. Open a separate bank account. Keeping business money apart from personal spending makes your tax return and your profit numbers far easier to read.
7. Choose where you sell. Your own website, or a marketplace that already has buyers searching. Most first-timers get their first sale faster on a marketplace.
8. List, learn and reinvest. Put up your first listings or offers, watch what converts, and put early profit back into more of what worked.

The registrations, and what they cost in 2026

This is the part the government pages cover well, so here is the short version with links to each one.

Sources: business.gov.au pages on registering for an ABN, registering a business name and registering for GST. Beware of websites that charge you to apply for an ABN on your behalf. The government application is free.

Beyond registrations, a lean online business needs very little. A domain name is optional if you sell on a marketplace. The real costs are the tools you choose, the marketplace's fees when you sell, and any stock you buy. Those depend on the model, which is why the model matters more than the paperwork.

The main online business models, compared

"Start an online business" hides four very different paths. Choosing one that doesn't fit your situation is the most common reason people quit in the first month.

Services pay quickly but cap out at the hours you can personally work. Content and affiliate sites usually take months before they earn anything, which is a slow burn that defeats most beginners. Digital products can pay well once they exist, but you need a finished, polished product before you make a dollar.

Reselling has the lowest barrier on the axes that matter to a first-timer: modest cash, no product to invent, and buyers already searching the marketplace. The honest downside is the workload. Done by hand, it means hours of product research, copying details into listings, watching supplier prices and placing orders. For a deeper look at picking products, our guide on what to sell on eBay goes further, and making money from home in Australia lays out the broader options if you're still deciding.

Selling on eBay Australia in 2026: the rules that shape your costs

If you choose marketplace reselling, eBay's Australian rules decide a lot of your costs. Here is what eBay's own pages say as of Sep 2026.

Free selling for smaller sellers. eBay's selling fees page says you pay no final value fees if you have a registration address in Australia, sell without an eBay Pro plan, and sold AU$25,000 or less on eBay in the past 12 months. All sellers get 250,000 free listings a month on eBay.com.au. If your sales go over the threshold, eBay notifies you on the 20th of the month and moves you to the Pro Starter plan from the 1st of the next month.

Pro Starter costs. Pro Starter has no monthly fee, but final value fees apply: 13.4% on sales up to AU$4,000, 2.5% on the portion above, and AU$0.30 per order, according to eBay's Pro plan fees page.

What needs a Pro plan. Several tools that a growing store uses are Pro-only, whatever your sales: multi-quantity listings and variations, alternative postage options, scheduled payouts, Discounts Manager and third-party tool integrations. eBay also limits the bulk listing tool, Seller Hub Reports and Product research to Pro sellers. Switching to a Pro plan ends free selling, so budget for final value fees once you need these tools.

Our guide to selling on eBay from first listing to repeat sales covers the day-to-day, and setting up eBay business policies covers postage, payment and returns settings.

Why a marketplace reselling store is our pick for a first online business

A disclosure first: Ecomli makes the tool described in the next section, and a reselling store run with Ecomli is our pick for most first-time founders. Here is the reasoning, and who it doesn't suit.

A reselling store on an established marketplace gives a first business the three things it most needs. Buyers are already there, so you aren't also trying to solve the hardest problem in e-commerce, which is getting people to your store. A product that flops costs you a listing rather than a warehouse of stock, as long as you buy carefully. And the work can fit around a full-time job, especially once the repetitive parts are handled by software. That is why so many Australians start here, and our comparison of side hustles in Australia puts marketplace reselling next to the alternatives.

It doesn't suit everyone. If you already have a skill people pay for, freelancing will pay you sooner. If you want no customer contact at all, reselling isn't it: buyers ask questions, parcels go missing, and returns happen. And if you can't spare a few hours a week for check-ins, no tool changes that.

How to do this in Ecomli: run a reselling store without the manual grind

Ecomli is a non-API browser extension for eBay dropshippers. It works through the eBay seller account already signed in to your desktop Chrome browser, so there is no API connection to authorize, and it uses Amazon and AliExpress as product sources. eBay is the only place it sells, and the rules of your eBay marketplace apply to everything you list. Here is how it removes each grind point:

1. Find products with evidence of demand. Product Hunting researches another eBay seller's sold history or current listings and matches the products to Amazon or AliExpress, or searches Amazon keywords and Best Sellers. You start from items that have already sold instead of a hunch. A match is evidence, not proof of profit.
2. List without the copy-paste. Create Listings reads the supplier product, prices it with your markup, writes optional AI titles and descriptions from the supplier facts, applies your description template and fills eBay's listing form in your seller session, up to 10 listings at once. Safety Shield screens products, AI copy and the draft for flagged brands and restricted items first. It is a checkpoint, not a guarantee.
3. Keep prices in line with supplier costs. Stock Monitoring checks Amazon and AliExpress stock and prices for your Ecomli listings and updates the eBay price and quantity, or ends out-of-stock items, by your rules.
4. Handle supplier orders. Starter uses manual ordering. On Pro, Basic Auto Ordering lets you click Auto Order and Ecomli places the supplier order in your own browser. On Scale, once you turn it on, Advanced Auto Ordering runs on Ecomli's servers and places the supplier order for new eBay orders without a click, as long as each order is within your buying limits (a maximum purchase price and a maximum loss). Orders outside those limits need manual handling.
5. See what the store actually makes. The Overview dashboard shows eBay sales, fees, Promoted Listings costs, refunds, supplier costs and recorded profit by day or period, so a margin leak shows up as a number.

Most of this runs in your browser while it is open, so plan a daily check-in for orders outside your limits and buyer questions. Plans are billed monthly in US dollars, from Starter at US$29 to Scale at US$199, and the Ecomli plans page shows what each includes.

Your first 30 days: a realistic start plan

You don't need to do everything at once. A launch you can sustain looks like this.

1. Week 1: foundations. Apply for your ABN, register a business name if you need one, open a business bank account and set up your eBay seller account. Read eBay Australia's fee pages before you choose suppliers.
2. Week 2: first listings. Research products with demonstrated demand and a workable margin after fees, and list a small first batch. Treat these as tests, not bets.
3. Week 3: set your rules. Decide your markup, what happens when a supplier runs out, and your buying limits. With Ecomli, this is when you turn on Stock Monitoring and, on Pro or Scale, Auto Ordering within those limits.
4. Week 4: review and reinvest. Look at what sold, end what didn't, and add more of what worked. Put early profit back into listings rather than spending it.

Frequently asked questions

What is the best online business to start in Australia?

Our pick for most first-timers is a reselling store on eBay run with Ecomli, the tool we make: buyers are already on the marketplace, there is no product to invent, and the repetitive research, listing and price-checking can be handled by software. It isn't the right fit if you already have a skill people pay for (freelancing pays sooner) or want no customer contact.

What do I need to start an online business in Australia?

An ABN (free), a business name registration if you won't trade under your own name (A$47 for 1 year or A$108 for 3 years), a separate bank account, and a place to sell, such as a marketplace account or your own site. You register for GST once your GST turnover reaches A$75,000, within 21 days of becoming aware you'll go over. Most solo founders start as a sole trader.

Can a foreigner start a business in Australia?

A business located outside Australia may be entitled to an ABN if it carries on an enterprise in Australia or makes supplies connected with Australia's indirect tax zone, according to the Australian Business Register's entitlement page. If you're in Australia on a visa, check your visa conditions before you start trading, because they can limit the work you may do. eBay's free selling also requires a registration address in Australia.

What business can I start with $100K in Australia?

Almost any online model, but you don't need that much to start one. A marketplace reselling store or a service business can begin with a small fraction of it, and keeping most of the money in reserve lets you test, learn and survive a slow first few months. If you do spend more, spend it on stock with proven demand and on tools that save you hours, not on a big launch.

How much does it cost to start an online business in Australia?

The registrations can cost nothing: the ABN is free, and a business name (A$47 for 1 year) is only needed if you won't trade under your own name. eBay selling is free of final value fees for Australian-registered sellers without a Pro plan who sold AU$25,000 or less in the past 12 months. Your real costs are tools, marketplace fees once you need a Pro plan, and any stock you buy.

Do I need an ABN to start an online business?

If you're running a business, yes in practice: you need one to register a business name or register for GST, and it's free to apply through the Australian Business Register. Someone selling a few personal items isn't running a business, but a store that buys stock to resell is.

Do I need my own website to sell online?

No. Many Australian sellers run entirely on marketplaces, because the marketplace supplies the buyers. A website becomes useful later for branding and direct sales, but you don't need one to make your first sale.

How long before an online business makes money?

There is no set timeline. A reselling store can sell once listings are live, but when the first sale arrives and what a month earns depend on your products, pricing and effort, and steady income usually takes months of listing and refining. Content and affiliate models are slower. Treat the first months as learning.
