Northbridge Piazza - Outdoor Event Area — Northbridge, WA. Northbridge Piazza's Outdoor Event Area is an open-air civic event space at 142 Lake Street in central Northbridge, managed by the City of Perth. The city promotes community performances, festivals, outdoor screenings, art events and cultural programming, supported by grassed areas and a permanent stage beneath the large public Super Screen. The outdoor event area and Super Screen may be hired separately or together through the city's event application process; this is not a conventional enclosed event room. Organisers need approval for their event footprint, power, logistics and expected crowd numbers, which are not stated as one universal legal capacity. Contact the venue operator for current availability, current hire rates and confirmation of event-specific inclusions before booking.
