Web devs, lock in May 3 and 4 as the dates for WebDU 2012 to be held at the Four Points Sheraton in Darling Harbour.

A day of workshops will be held on May 2, 2012.

The conference has also issued a call for papers, with potential speakers required to submit a relevant topic for a 50-minute session.  The WebDU site says that just about anything to do with web and rich internet-application development and related topics will be considered. Submissions are due by January 8, 2012.

WebDU 2012 will be the ninth year that the conference has taken place.
