Which Domain Extension is Right for Your Australian Business?

In 2025 your domain name is your online identity. For Australian businesses, the choice between a .com and a .com.au domain extension can significantly impact your online presence and search engine optimisation (SEO) efforts. Let’s dive into a comprehensive comparison to help you make an informed decision.

What’s the Difference?

Before we delve deeper, let’s clarify the basic differences:

  • .com: A global top-level domain (TLD) used worldwide
  • .com.au: An Australian country code top-level domain (ccTLD) specifically for Australian entities

Pros and Cons: .com vs .com.au

.com Domains

Pros:

  1. Global recognition
  2. Easier to remember
  3. Potential for international expansion

Cons:

  1. Higher competition for domain names
  2. May not clearly indicate Australian presence

.com.au Domains

Pros:

  1. Clear Australian identity
  2. Potentially better local SEO performance
  3. Higher trust factor for Australian customers

Cons:

  1. Limited to Australian-based entities
  2. Stricter registration requirements

SEO Considerations

When it comes to search engine optimisation, both domain extensions have their merits. Here’s what you need to know:

Local SEO

If your target audience is primarily Australian, a .com.au domain might give you an edge. Google and other search engines often prioritise local results, and a .com.au domain is a strong signal of Australian relevance.

Global SEO

For businesses with international aspirations, a .com domain offers more flexibility. It’s universally recognised and doesn’t limit your perceived market to a specific country.

Actionable Tip: Regardless of your chosen domain, focus on creating high-quality, relevant content and building authoritative backlinks. These factors often outweigh the impact of TLD choice on SEO performance.

Trust and Credibility

In the Australian market, a .com.au domain can instil a sense of trust and local presence. Australian consumers often feel more comfortable dealing with clearly identifiable local businesses.

However, a .com domain doesn’t necessarily diminish trust. Many well-known Australian brands successfully use .com domains. The key is to clearly communicate your Australian identity through your website content and branding.

Availability and Registration

.com Domains

  • Open to anyone
  • No geographical restrictions
  • Often more competitive and expensive for popular names

.com.au Domains

  • Restricted to Australian entities (businesses, organisations, or individuals)
  • Require an Australian Business Number (ABN) or other eligible identifiers
  • Generally less competition for names, but stricter eligibility criteria

Making Your Decision

Consider these factors when choosing between .com and .com.au:

  1. Target Audience: Primarily Australian or international?
  2. Business Goals: Local focus or global expansion plans?
  3. Brand Identity: How important is the “Australian-ness” of your brand?
  4. SEO Strategy: Local SEO benefits vs. global reach
  5. Availability: Is your preferred name available in both TLDs?

The Hybrid Approach

Can’t decide? Some businesses opt for both:

  • Use .com.au as the primary domain for the Australian market
  • Secure the .com version and redirect it to your main site
  • Consider separate .com site for international audiences if needed

This strategy allows you to leverage the benefits of both domain extensions.

Conclusion

There’s no one-size-fits-all answer to the .com vs .com.au debate. Your choice should align with your business goals, target audience, and overall digital strategy.

Remember, while your domain choice is important, it’s just one piece of the digital marketing puzzle. Focus on creating value for your audience, optimising your website for search engines, and building a strong online presence regardless of your chosen TLD.
