Bulletin information will be available from the Microsoft web site
soon after their release, and AusCERT will be distributing bulletins

Historically, exploits targeting Microsoft vulnerabilities are
released in the days immediately following their announcement, so it
is critical that system administrators apply patches or mitigate
vulnerabilities as quickly as possible.
