The AustralAsian Intervarsity Debating Championships has its own unique debating style, generally referred to as Australs style.

Australs style debating consist of two teams of three speakers each, one team taking the role of the Affirmative, and the other the Negative. Speeches are heard alternately from the Affirmative and Negative, and have a duration of six to eight minutes. At the conclusion of the six substantive speeches, each team gets the opportunity to deliver a short Reply Speech of four minutes which wraps up the debate for each side. Both teams are given 30 minutes to prepare their speeches, from the time the topic is announced.

Australs style debating is an exciting and engaging form of discourse. To succeed, debaters are required to have a broad range of knowledge, strong teamwork skills and the ability to think creatively on their feet. Debaters are judged on their knowledge of the topic and depth of analysis, as well as their persuasive skills and ability to sway an impartial adjudicator.

The teams at Australs are required to debate a diverse array of critical issues confronting society. Previous topics have included:

* That we should boycott countries that nationalise their oil companies

* That we should abolish detention without trial

* That gun ownership should be restricted to law enforcement agencies

* That executive bonuses should be pegged to corporate performance

* That there should be minimum weight requirements for models
