The College Union includes all past and present resident students who choose to join. The Union funds the newsletter Boomalakka and makes small travel grants to students for approved purposes. There is a biennial dinner, and frequent year-group reunions and other activities. The Secretary of the Union and the Alumni Officer are the two main points of contact.
The St Paul’s College Women’s Organisation was founded in 1927 for women with family connections to past and present Paul’s students. It is a vital part of the College family. Every year it funds some small but significant improvement to the daily life of the students, the cumulative effect of which has been enormous.
