A side hustle is a small job or business you run alongside your main work — freelancing on weekends, tutoring in the evenings, selling something you make, or driving deliveries when it suits you. Done well, it brings in extra money without forcing you to quit your day job. Done badly, it eats your evenings and creates tax headaches. This guide walks through how to start a side hustle properly, step by step, so you can earn extra income with fewer surprises.
Quick answer: Pick one skill you can already sell, check that your work contract allows outside work, register for an ABN through the Australian Business Register if you are running a business, set a price, find one paying customer, and keep simple records from day one. Most people can get the basics in place within a week or two.
Step 1: Pick one idea you can actually sell
Start with what you already know how to do, not with a brand-new skill you still have to learn. Good starting points include writing, design, tutoring, pet sitting, gardening, cleaning, photography, handyman work, or selling handmade goods. Ask yourself three questions:
- What do people already ask me for help with?
- Can I deliver this in a few hours a week?
- Would someone pay for it this month, not someday?
If you cannot answer the third question, the idea is too vague. Narrow it down. “I will edit short videos for local cafes” beats “I will do social media”. One clear offer is easier to sell than ten fuzzy ones.

Step 2: Check your work contract first
Before you earn a dollar, read your employment contract and any workplace policy on outside work. Look for clauses about outside employment, conflicts of interest, non-compete rules, and confidentiality. Some employers require you to disclose or get approval for extra paid work, and some bar work that competes with their business. If anything is unclear, ask HR in writing — a short email now saves an awkward conversation later.
Even when your contract is silent, keep the two worlds apart: do side work on your own time, on your own devices, and never use your employer’s clients, tools, or confidential information. If your side hustle would compete directly with your employer, that is a red flag — pick a different idea rather than risking your main job.
Step 3: Test the idea before you spend money
You do not need a logo, a website, or business cards to start. You need one paying customer. Offer your service to three people you know, post in a local community group, or list on a platform that fits the work — for example, Airtasker for odd jobs, Upwork or Freelancer for online services, or Mad Paws for pet sitting. Charge a fair starting price, deliver well, and ask for a short review.
That first paid job tells you more than weeks of planning: whether people want it, what they will pay, and how long it really takes. If nobody bites after a few genuine attempts, change the offer or the audience before spending anything on it.
Step 4: Sort out the ABN and tax basics
If you are running a business — doing paid work regularly with the aim of making a profit — you generally need an Australian Business Number (ABN). Applying through the Australian Business Register is free, and there are no ongoing fees to hold an ABN. A hobby, like occasionally selling a few personal items, is different and does not need one, but regular paid work usually does.
As a sole trader, you report your business income on your individual tax return and pay tax on your profit — income minus genuine business expenses. Keep it simple from the start:
- Use a separate bank account for side-hustle money, even if it is just a second everyday account.
- Put aside roughly a quarter to a third of what you earn for tax, so tax time does not sting.
- Keep invoices and receipts for at least five years.
You must register for GST once your GST turnover reaches $75,000 in a 12-month period (ride-share drivers are an exception and must register regardless of income). Below that threshold, GST registration is optional. If your turnover is getting close to the threshold, or you are unsure whether you are a business or a hobby, talk to a registered tax agent — it is usually cheaper than fixing a mistake later.
Step 5: Set your price and your hours
Price by the job or by the hour, and work out what you actually keep after costs and tax. A rate that sounds good before expenses can look thin once you subtract travel, materials, platform fees, and the tax you need to set aside. Check what others charge for similar work in your area, then price near the middle while you build reviews — undercutting everyone is hard to climb back from.
Decide your hours in advance and protect them. Two evenings and a Saturday morning is a realistic starting block for most people with full-time jobs. Tell customers when you are available and when you are not. A side hustle that bleeds into every evening will not last, and neither will the energy for your day job.
Step 6: Get set up properly, but keep it cheap
Once the idea is earning, tidy up the basics:
- Business name: If you trade under a name other than your own, you need to register it. Trading under your own name does not need a separate registration.
- Payments: Make it easy to get paid — bank transfer, a payment link, or an invoicing app. Always invoice, even friends.
- Insurance: Think about public liability insurance if you work in people’s homes or with their pets. Some platforms include cover; check what is actually included.
- Licences: Most everyday services need no licence, but food, alcohol, childcare, and some trades do. Check the rules for your specific work before you start selling it.
Spend money only on things that help you earn: a basic tool, a second-hand piece of equipment, or a simple invoicing app. A fancy website can wait until the work is steady.
Step 7: Find customers without spending a fortune
Your first customers usually come from people who already trust you: friends, neighbours, colleagues (outside work hours), and local community groups. After that, a simple profile on the right platform does most of the work. Ask every happy customer for a review and permission to share it — reviews are the cheapest marketing a side hustle has.
Post useful content, not ads: a before-and-after photo of a garden job, a short tip from a tutoring session, or a quick video of a product being made. People hire people they have seen do the work. Keep your side-hustle accounts separate from your personal ones so customers see the work, not your weekend.
Common mistakes to avoid
- Starting five ideas at once. One idea, done properly, beats five half-started ones.
- Working for free for too long. One free job for a review is fair; ongoing free work is not a business.
- Mixing money. When side income lands in your everyday account, tax time becomes guesswork.
- Ignoring the contract. A side hustle is not worth losing your main job over.
- Quitting too early. Most side hustles take a few months to find their rhythm. Judge it after 10 paying jobs, not after two quiet weeks.
When to grow — or stop
Review your side hustle after three months. Are you earning enough for the hours it takes? Do you enjoy it? Is your day job still getting your best energy? If the answers are yes, consider raising prices, narrowing your offer, or setting aside money for better tools. If the work is draining you or barely covering its costs, it is fine to pause it or try a different idea — a side hustle should improve your life, not just fill it.
The bottom line
Starting a side hustle comes down to a simple sequence: pick one sellable skill, check your contract, test it with a real customer, sort the ABN and tax basics, set honest prices and hours, and keep clean records. You do not need much money to begin — you need a clear offer, a first customer, and a system that keeps the money and the paperwork tidy. Get those right, and the extra income follows.
