How secure are Australia's business domains?
Most businesses in Australia use a .au domain. Across 2,226,672 of them, here's how their security stacks up — aggregate patterns only, never an individual business. As of 2026-06-28.
We use .au as a stand-in for Australia, based on the domain's ending rather than where a company is legally registered — so a Australia business on a generic ending like .com isn't counted here.
