International conferences are held annually in the summer, the first one being a science conference in 2006. Leading universities and tertiary institutions have joined SPCC as co-organisers in some of these international endeavours. The annual conference aims to give students a chance to learn, share and exchange ideas with students from around the world.
In July 2017, SPCC joined by The University of Hong Kong to co-host the International Student Science Conference again.
