Mercure Ballarat Convention Centre is a 690 m² large-scale event venue, with operator-advertised capacity for up to 600 seated guests. The hotel’s own Convention Centre page describes flexible configurations, in-house event catering, event-planning support and integrated audiovisual technology. A separate regional tourism chart lists higher theatre and cocktail figures; to avoid overstating bookable occupancy, this listing uses the hotel’s explicit 600 seated configuration and flags larger layout figures for confirmation. The centre connects to hotel accommodation and other function spaces for conferences, awards and gala events. Confirm current availability, specific inclusions and final hire conditions directly with the operator.
