Melbourne Convention and Exhibition Centre (MCEC) Acknowledges the Traditional Owners of Narrm, the Wurundjeri Woi Wurrung people of the Kulin Nation. We pay our respects to their Elders past and present, and to Elders of all First Nations communities that visit MCEC.

Plenary is a world-renowned architectural marvel at the heart of the Convention Centre, great for conferences, speaker events and concerts. Plenary 1 or 3 can be sectioned from the larger theatre, creating a smaller theatre seating up to 1,482 guests. It provides your delegates and speakers with easy access to neighbouring meeting rooms, exhibition spaces, a banquet room and on-site accommodation.
