If you're an Australian business, this question comes up almost every time.
Here's a simple way to think about it:
com.au signals that you're an Australian business. It builds local trust, tends to rank better in Australian search results, and tells your customers exactly where you operate. To register one, you need an ABN or ACN.
com is globally recognised and gives you flexibility if you ever plan to operate internationally. It's not tied to any country, which makes it more versatile long term.
Our recommendation? Get both if you can β lock in your name across both extensions so nobody else can take either.
SUMB can help you register your domain and get your business online. π
