Email Security in Australia
SPF, DMARC and DNSSEC: how much of the .au namespace is actually protected against spoofing and hijacking.
SPF, DMARC & DNSSEC adoption
Email authentication is widely deployed (SPF 46.5%, DMARC 23.0%), but DNSSEC lags badly at 1.1%, roughly a quarter of the global average.

DNSSEC signing across .au
Just 1.16% of registered .au is DNSSEC-signed, the namespace's weakest link. Signing is unchanged on July 2026.
