Debating is an enjoyable activity that develops confidence and an ability to work in a team, research and logically argue both sides of a given topic, and speak confidently. Debating has been strongly supported in the College for many years with opportunities for participation in inter-House and inter-school competitions. Both experienced and new debaters are welcome to join the teams in early February each year. Astute coaching of the many talented young men has frequently resulted in competition victory.
Each year St. Patrick's takes part in the Queensland Debating Union (QDU) Schools Competition and acts as a host school for one or more year levels. The competition runs across most of the year, with preliminary debates held monthly in Terms 1 and 2 and finals held during Terms 3 and 4. Students in Years 7 to 12 are able to join teams competing in the QDU competition, with the College regularly participating in the finals' rounds, particularly in Year 12.
