Opera House chief executive Louise Herron said the project had improved the acoustics for artists and audiences in both orchestral and amplified mode, enhanced access for people with mobility needs and provided a more flexible and safer working environment for staff behind the scenes.
“You can feel the clarity and warmth now in both amplified and symphonic mode; the range of sound is much clearer now,” Herron said.
“I was blown away when I first heard it.”
A new lift and passageway improve accessibility, making it possible for wheelchair users and people with limited mobility to access all levels of the hall independently.

The opening concert, a performance of Gustav Mahler’s Symphony No.2, the Resurrection Symphony, will take place next Wednesday under the helm of the Sydney Symphony Orchestra’s Simone Young. Didgeridoo player William Barton will play his composition Of the Earth, accompanied by performers with 60 pairs of clapsticks made using brushbox timber salvaged from the Concert Hall’s old and new stages.
Given that half of the Opera House’s revenue comes from international tourists, Herron is hoping the reopening will be a boon for the house, which has had its revenue cut by 73 per cent since the COVID pandemic.
“This Concert Hall is ready now for the next generation and the next 50 years,” she said.
Since the venue closed for renovations in February 2020, hundreds of construction workers, acousticians, and architecture and heritage experts have been busy delivering the biggest upgrade to the Concert Hall since it opened almost 50 years ago, with all possible care and attention taken to protect and respect the heritage of this treasured performance space.

The Concert Hall is one of the largest – with 2600 seats – and longest – at 45 metres – performing arts halls in the world. It reaches 25 metres from the stage to the crown above. Perfecting the sound quality for both acoustic and amplified performances across this space was a highly technical challenge for acousticians.
At Thursday’s walk-through, NSW Minister for the Arts Ben Franklin said, “The Concert Hall is the beating heart of the Opera House.
“The renovation is a technical triumph, it will make it one of the greatest concert halls of the world.”
