This paper describes the design of a supervised verifiable voting protocol suitable for use for elections in the state of Victoria, Australia. We provide a brief overview of the style and nature of the elections held in Victoria and associated challenges. Our protocol, based on Prêt à Voter, presents a new ballot overprinting front-end design, which assists the voter in completing the potentially complex ballot. We also present and analyse a series of modifications to the back-end that will enable it to handle the large number of candidates, 35+ , with ranking single transferable vote (STV), which some Victorian elections require. We conclude with a threat analysis of the scheme and a discussion on the impact of the modifications on the integrity and privacy assumptions of Prêt à Voter. [less ▲]
