You want a website. Someone tells you to “register a domain.” You nod, open a new tab, and realise you’re not entirely sure what that means or where to start.
Domain name registration doesn’t need to be complicated. This post explains what a domain name is, how it relates to your website and hosting, and exactly what to do to secure one.
What is a domain name?
A domain name is the address people type to find your website. Something like yourcompany.com.au or melbourneplumber.com.
Computers talk to each other using numerical addresses called IP addresses. Domain names exist so that humans don’t have to memorise strings of numbers. When someone types your domain into a browser, the internet quietly translates it to the right IP address and loads your site.
Here’s how a domain name breaks down:
www . yourcompany . com.au
↑ ↑ ↑
subdomain your name TLDThe part after the dot, like .com, .net, or .com.au, is called a top-level domain (TLD). .com is the most recognised globally. .com.au is restricted to Australian businesses and signals local credibility. .io has become common in the tech space. For most small businesses, .com.au or .com is the right call.
Domain, hosting, website: what’s the difference?
This trips up almost everyone the first time.
- Domain name: Your address. It’s what people type to find you.
- Web hosting: The server where your website’s files actually live.
- Website: The thing people see when they arrive.
You need all three, but they’re separate things you often buy from separate providers. Think of it like this: the domain is your street address, hosting is the land your building sits on, and the website is the building itself.
You can complete domain name registration today without having a website or hosting yet. Many people do this just to lock in a name before someone else takes it.
How do you choose a good domain name?
A few principles that hold up:
Keep it short. Shorter domains are easier to type, say out loud, and remember. If you’re spelling it out to someone on the phone, every extra word is a liability.
Match your brand. Ideally, your domain matches your business name. If yourbusiness.com.au is taken, try a simple variation before defaulting to hyphens or unusual spellings, both of which create confusion.
Avoid hyphens and numbers. They look untrustworthy and are easy to mistype. If you need them to get a name, the name is probably worth rethinking.
Check for conflicts. Before you register, do a quick search to make sure you’re not stepping on a trademarked name. ASIC’s business name register and IP Australia’s trademark search are worth checking.
Think about TLD. For an Australian audience, .com.au carries more local credibility, but there’s a catch.
Do you need an ABN to register a .com.au domain?
Yes. To register a .com.au domain, you need to demonstrate an “Australian presence.” In practice, this means supplying an ABN (Australian Business Number) or ACN (Australian Company Number) at checkout.
This requirement is managed by auDA, the body that administers .au domains. It exists to protect the integrity of the Australian web space and prevent overseas entities from camping on local business names.
If you don’t have an ABN yet, you have two options: register a .com domain in the meantime, or get your ABN sorted first (which is free and takes about ten minutes through the Australian Business Register).
Domain name registration: a step-by-step guide
1. Choose a registrar. A registrar is a company authorised to sell domain names. In Australia, well-regarded options include VentraIP and Crazy Domains, both Australian-owned with good local support. If you prefer an international option, Hover is a clean, no-upsell registrar with a strong ethical reputation. Prices are similar across the board. Service quality and support vary more than cost.
2. Search for your domain. Use the registrar’s search tool to confirm availability. Most will also suggest alternatives if your first choice is taken.
3. Select a registration period. You can usually register for 1–5 years. Registering for 2 years upfront avoids the risk of forgetting to renew.
4. Understand your privacy options. When you register a domain, your details are stored in a public database called WHOIS. For .com.au domains, auDA’s rules mean your business name and ABN are publicly visible (intentional, as a trust signal), but personal contact details are largely protected by default. For .com domains, privacy protection is worth adding. Most registrars offer it for a few dollars a year, and it replaces your personal details with generic contact info.
5. Complete checkout. You’ll create an account and pay. Once processed, the domain is yours for the registration period.
How much does domain name registration cost?
Standard .com.au domains typically run $15–$30 per year. .com is similar. Premium or short domains can cost significantly more.
Watch for first-year discounts that revert to a higher renewal price. Check the renewal rate before you commit, not just the introductory offer.
What happens if you let a domain expire?
Most registrars send renewal reminders, but it’s worth setting your own calendar reminder too, because the consequences of missing one aren’t trivial.
When a domain expires, there’s typically a short grace period (around 30 days) where you can still renew it. After that comes a redemption period, where the domain is suspended but can still be recovered, usually for a steep fee. After that, it’s released back to the public, and anyone can register it, including domain squatters who buy expired names and hold them hostage at inflated prices.
Set a reminder. It’s not worth the stress.
What happens after you register?
Once you’ve registered a domain, you’ll need to connect it to hosting before a website can load there. This involves updating DNS records (Domain Name System). Your registrar or hosting provider will walk you through it. DNS changes can take anywhere from a few minutes to 48 hours to propagate. That’s normal.
If you have a developer or agency lined up, hand them your registrar login details and they’ll handle the technical side.

Frequently asked questions
Can I buy a domain without having a website yet? Yes. You can register a domain and leave it parked until you’re ready to build. It just sits there holding your name.
What if someone already has my domain name? Try a different TLD, a slight variation, or contact the owner. If someone is squatting on a trademark you own, there are formal dispute processes through ICANN and auDA for .au domains.
Can I transfer my domain to a different registrar? Yes. The process varies by TLD but generally takes a few days and requires an authorisation code from your current registrar.
Do I own my domain forever once I buy it? No. You rent it for the period you’ve paid for. See the expiry section above for why renewing on time matters.
The practical checklist
Figuring out domains, hosting, and how it all fits together can feel like a lot when you’re just trying to get a website up. If you’d like a plain-language conversation about what your project actually needs, we’re happy to talk it through. No jargon, no obligation.
