Australian Business Registration Checklist: ABN, ASIC & Domain Names

Business Guide10 Apr 2026

Starting a new business is exciting, but the paperwork can be daunting. Here is a simple, straightforward checklist to make your business official in Australia.

Step 1: Get Your ABN

The Australian Business Number (ABN) is essential for tax purposes and invoicing. It's free to apply for through the Australian Business Register (ABR).

Step 2: Register Your Business Name

If you're not trading under your exact personal name, you must register your business name with ASIC.

Step 3: Secure Your .com.au Domain

Before you lock in your ASIC registration, check if the matching website domain is available. In Australia, you need an ABN to register a .com.au domain.
