Preface [to the 2005 Australian Communications Theory Workshop]

This year marks the sixth AusCTW, which now visits Brisbane. The production of published proceedings in both hard-copy and CD-ROM for peer-reviewed papers, along with a book of abstracts, has provided a permanent conference record, contributing to and complementing the tradition of the Workshop. The incorporation of the proceedings into IEEE-Xplore will significantly widen the audience of the research presented.
