The primary resource for debaters and adjudicators in AustralAsia is the Australia-Asia Debating Guide, available from the Debating Association of Victoria website.  This guide, written by AIDA Life Member Ray D'Cruz, is a good starting point for all things debating related.

Other resources:

• http://flynn.debating.net/ contains a wealth of knowledge on debating technique, preparation and knowlege.
• http://www.idebate.org/ is a good resource for a wide range of topics.
• http://learndebating.com/ is aimed primarily at school students, but is a good coverage of the basics of debating.

AIDA is in the process of putting together more training materials.  If you are interested in helping with that process, please get in touch!
