Heritage Action Plan

As temporary custodians of this State, National and World Heritage site, we are committed to ensuring the Sydney Opera House’s heritage significance – the building and its functions as a performing arts centre and gathering place for the community – is conserved and celebrated for current and future generations.

The Heritage Action Plan 2022-25 sets out the Opera House’s priorities and ambitions for heritage management over the next four years. It aligns with and supports the Utzon Design Principles, Conservation Management Plan and the Sydney Opera House Strategy 2018-23 to achieve our vision, mission and values.

Cultural heritage fosters peace and mutual understanding between peoples and nations, and is a driver and enabler of sustainability. Together with our other community actions plans, the Heritage Action Plan 2022-2025 underpins the Opera House’s commitment to the United Nations Global Goals, which provide a roadmap to a more sustainable and prosperous future for all.

[The Sydney Opera House] stands by itself as one of the indisputable masterpieces of human creativity, not only of the 20th century but in the history of human kind.

Conservation is the care and continuing development of the Opera House in such a way that its significance is retained or revealed and its future secured.

Dr James Semple Kerr, The Conservation Plan 2013

Why is the Sydney Opera House significant?

The Opera House is one of the great buildings of the 20th century and Australia’s pre-eminent performing arts venue. The epitome of excellence and creativity, it elevates and enriches the human experience. Its heritage significance is founded in:

  • The Opera House’s function, form, materials, colour, spaces and setting;
  • Its unique combination of architecture, engineering, design and the performing arts;
  • The building’s central role in the life of the city and in Australian culture and identity; and
  • The cultural traditions of the Gadigal and the connection to Country.
