The Musical Theatre section stages annual musicals in Timaru's Theatre Royal. This is the major work for the section and the SCDL. These productions require a large number of performers and support crew and it gives the SCDL an opportunity to showcase the local talent on a big stage and in a big theatre.
As with the Junior Section the large sets are usually built at the Playhouse and transported to the Theatre Royal. Musicians, Sound and Lighting Technicians are contracted and the Director is required to transfer rehearsals from the Playhouse to the Theatre Royal within the relatively short hire period of the Theatre Royal.
