Method. Figures are the latest available snapshot (July 2026), refreshed each edition. Registry figures come from a full RDAP sweep of the registered .au universe (3,798,553 names); infrastructure figures (hosting, email, DNS, builders, authentication) come from a DNS-enrichment sweep and use heuristic provider labels (ASN / MX / nameserver patterns), so treat them as indicative shares.
