Your domain extension says more about your brand than you might think. It's the first clue visitors get about who you are, what you do and how credible your business feels online.

Here in Australia, a .com.au address tells customers you're a local business they can trust. Globally, .com still dominates — it accounts for nearly half of all registered domains worldwide — but today's domain space is packed with alternatives that let you shape your identity your way, from .ai for tech innovators to .store for ecommerce brands and .co for startups ready to scale.

Let's walk through the most common domain extensions in 2026 — starting with the Australian ones — and how to choose the right one for your business website.

The most popular domain extensions in 2026

When choosing a domain, start with what feels familiar to your audience. Look at which domain extensions are most common in your industry and pick one that aligns with your brand and customer expectations. For Aussie businesses targeting local customers, that often means leading with a .com.au or .au. If your audience is global, a classic .com or a trendier TLD like .ai or .io may be the better call.

Here are the top domain extensions to consider in 2026 — Australian options first, then the global favourites.

Let's take a closer look at each one.

1. .com.au

A .com.au domain is the most recognisable extension for Australian businesses — think of names like bunnings.com.au or woolworths.com.au. Local customers are used to seeing it, and it's a strong signal that your business is based in Australia and plays by local rules.

To register a .com.au, you'll need an eligible Australian presence (such as an ABN, ACN or registered business name) and the domain must have a close and substantial connection to that entity. It's an easy win for building trust with Aussie customers from the moment they land on your site.

2. .au

Introduced as a direct namespace, .au gives Australian businesses and individuals the chance to grab a shorter, snappier domain — like yourbrand.au instead of yourbrand.com.au. It's modern, clean and great for brands wanting a bold, uniquely Australian identity.

Eligibility is similar to .com.au: you need to be an Australian person, business or organisation. If you already own the matching .com.au, it's worth securing the .au version too, so no one else can.

3. .net.au

The .net.au extension is the Australian cousin of .net. Originally aimed at internet service providers and network-focused businesses, it's now a popular alternative for Aussie tech companies and digital brands when the .com.au is already taken. Eligibility rules mirror .com.au — you'll need an Australian business presence.

4. .org.au

The .org.au TLD is the home of Australian charities, not-for-profits, associations and community groups. If your organisation is incorporated as an association, a registered charity or a similar not-for-profit entity in Australia, .org.au instantly tells visitors you're mission-driven and locally based. It's a strong choice over the global .org when your audience is primarily Australian.

5. .com

A .com domain, like Amazon.com, is hands-down the most popular TLD in the world. It was originally used to designate for-profit businesses, but it's now the go-to for just about any type of site. Because it's so familiar, people instinctively type .com when entering a web address, which helps boost recognition and credibility — especially if you're targeting a global audience.

If your ideal .com is already taken, you can explore premium domain name options, buy the domain from the current owner, or set up a domain backorder to be notified when it becomes available.

6. .net

Much like .com, the .net extension (short for "network") is open to anyone. It was originally intended for internet service providers and networks, but it's now a popular alternative to .com. It's less crowded, so you're more likely to find your preferred name available. The .net TLD is best suited to companies with a digital or technical focus, like Behance.net.

7. .org

The .org extension was designed for not-for-profit organisations but is now available to anyone. It's a popular pick for NGOs, charities, political parties and online communities, like UNICEF.org. As one of the original TLDs, .org is recognisable and authoritative, and names are often easier to score than on .com. That said, it's not ideal for ecommerce or for-profit brands — users don't typically associate .org with selling products.

8. .co

The .co TLD was originally the country code for Colombia, but it's grown into a popular global option. It works well for companies positioning themselves as innovative or trend-driven, like 500.co. It's also more available and often more affordable than premium .com domains. The one catch: some visitors may type .com out of habit, so it pays to secure a matching .com or .com.au where you can.

9. .ai

The .ai TLD has quickly become a favourite among tech companies, startups and innovators in the artificial intelligence space. While it originally represented the country code for Anguilla, it's now widely recognised as a symbol of cutting-edge technology and forward thinking. That makes .ai a strong pick for businesses in software, robotics or digital services, like perplexity.ai.

10. .io

Originally tied to the British Indian Ocean Territory, the .io TLD has grown into a favourite among developers, SaaS companies and gaming platforms, such as pendo.io. It feels clean and cutting-edge, so it's a strong choice for digital-first brands that want to look sleek and innovative.

11. .xyz

.xyz is a creative, unconventional domain extension that appeals to brands and individuals who want to stand out. It's popular among creators, blockchain projects and next-generation businesses looking for something bold and memorable — like abc.xyz, the home of Alphabet (Google's parent company).

12. .shop

The .shop TLD instantly tells visitors they're in a place to browse and buy. It's great for retailers and ecommerce businesses that want to put products front and centre while keeping the web address short and intuitive. A well-known example is netflix.shop.

13. .pro

The .pro TLD is built for professionals and businesses that want to emphasise expertise and credibility. Originally limited to licensed professionals, it's now open to anyone and is commonly used by consultants, agencies, software companies and service providers wanting to highlight their professional focus. It's also used by some gaming-related websites, like deckshop.pro.

14. .store

The .store TLD is designed for retail and ecommerce brands. It makes your online shop instantly recognisable and pairs nicely with your main .com.au or .com domain to create a direct storefront. For example, dudeperfect.store leaves no doubt about where to go when it's time to buy.

15. .online

As one of the most adaptable domain extensions, .online works for virtually any type of business or personal brand. It emphasises accessibility and web presence, which makes it a great fit for freelancers, startups and organisations that operate fully online. One example is notepad.online.

16. .inc

Professional, credible and premium — the .inc TLD is built for incorporated businesses, such as whill.inc. It instantly signals legitimacy and corporate standing, making it a strong choice for established companies and startups chasing an executive image. It can also lift investor and client confidence.

Note: In Australia, most companies are structured as Pty Ltd rather than "Inc.", but .inc is still a valid option if you want a global, corporate feel.

17. .info

The .info TLD is ideal for websites focused on education, data or resources, such as mta.info. It signals that your content is there to inform rather than sell, so it's perfect for blogs, directories and information hubs. It helps position your site as a go-to source for reliable knowledge.
