The Immigration Museum Courtyard is a leafy outdoor event space inside the historic former Customs House site at 400 Flinders Street in central Melbourne. The landscaped courtyard offers an atmospheric setting for receptions, cultural events and corporate gatherings, distinct from the museum’s indoor Long Room and Atrium. Guests can approach from Market Street, and Museums Victoria lists ramped accessible entry from this side of the building and accessible toilets by the Festivals Courtyard. Confirm the permitted event format, weather contingencies, catering and hire capacity directly with Museums Victoria, as these are not specified for this exact courtyard on the source page.
