SC Magazine reports that a phased rollout of DNSSEC will begin in Australia next month. From the article:

Next month, regulator auDA (the .au Domain Administration) and its wholesale domain name provider AusRegistry will phase in the Domain Name Security (DNSSEC) protocol across Australian domain names such as those ending in com.au and net.au.  The regulator said the five-stage process will gradually bring domain name owners into the fold as it tests systems over coming months, before rolling out the technology to the mass market.
