State Theatre, Theatre at Arts Centre Melbourne, Australia

The State Theatre is an underground auditorium at Arts Centre Melbourne, entered from St Kilda Road by the Yarra River. It seats over 2,000 people and its stage ranks among the largest in the world. Opera Australia and The Australian Ballet use it as their main Melbourne venue.

The current State Theatre opened in October 1984 as part of The Arts Centre, near the Yarra River. Its first performances were Opera Australia's Fiddler on the Roof in May 1984 and the Victoria State Opera's Don Carlos, in John Copley's production, in August. An earlier State Theatre of 1929 on Flinders Street, with 3,371 seats, was renamed the Forum Theatre in 1963.

Opera Australia and The Australian Ballet both use the State Theatre as their main Melbourne venue. The first performances in May and August 1984 were Opera Australia's Fiddler on the Roof and the Victoria State Opera's Don Carlos, staged by John Copley. The Production Company also gave short seasons of musical theatre here before closing.

The State Theatre sits underground within Arts Centre Melbourne, entered from St Kilda Road at 100 St Kilda Road, beside the Yarra River. Trams run along St Kilda Road and the Southbank promenade is a short walk away. Because the auditorium is below ground, allow time to descend to the foyer before the performance.

The first State Theatre, built in 1929 on Flinders Street with 3,371 seats, was renamed the Forum Theatre in 1963. Its double-console Wurlitzer organ, the first built west of Chicago, was later moved to Moorabbin Town Hall. The current underground theatre opened in October 1984.
