The Victorian Head of the River regatta is contested between the eleven Associated Public Schools of Victoria (APS). The Head of the River is the oldest continuous schoolboy rowing event in the world, dating back to 1868, and throughout its history has changed format on a number of occasions: from a duel-style race between Melbourne Grammar and Scotch College on the Yarra River in Melbourne, to the current regatta, with the race usually being the last of the official APS rowing season. The race has been rowed on Lake Nagambie since 2001, which is a full-buoyed international standard course allowing six-boat finals.
