What are ABN and ACN in Australia
An Australian Business Number (ABN) is an 11-digit unique identifier issued by the Australian Business Register (ABR). It is used to identify businesses and individuals operating as sole traders, freelancers, contractors, or under any business structure within Australia. Whether you’re starting a small side hustle, freelancing, or launching a full-scale business, an ABN is often the first official registration step.
✅ Who Needs an ABN?
You need an ABN if you:
- Are you running or starting a business in Australia
- Work as an independent contractor, consultant, or freelancer
- Sell products or services online or in person with the intention of making a profit
- Operate as a sole trader, partnership, company, or trust
🔹 Even international students in Australia can apply for an ABN if they work independently or operate a small business (e.g., Uber Eats, graphic design, online selling).
🎓 Do Students Need an ABN?
Yes, international students who plan to work as freelancers, independent contractors, or gig workers must apply for an ABN. Common examples include:
- Food delivery (Uber Eats, DoorDash)
- Ride-sharing (Uber, Ola)
- Freelancing (design, IT, content writing)
- Online businesses (dropshipping, tutoring, etc.)
👉 Important: Students must comply with their visa work restrictions, which generally allow up to 48 hours per fortnight during academic sessions.
