Despite a few dubious looks from the staff on duty, in my most recent visit to the Wendouree Centre for Performing Arts I managed to feign enough confidence to get right into the centre of the theatre, in the midst of the Band section of the Royal South Street competition.
Royal South Street competition at the Wendouree Centre for Performing Arts
The theatre has impressive acoustics and comfortably seating 857 patrons, it is host to a variety of events year-round. It's offered for hire and there are also a number of function rooms, with catering options available.
The Wendouree Centre for Performing Arts is located at 1220 Howitt Street Wendouree. There is disabled access and a hearing aid loop system available, but parking is limited.
Office hours are restricted, so it's best to check their website for further details and upcoming events.
