Powerhouse Parramatta: Here’s What’s Coming
Western Sydney is about to get something it has never had before — a world-class museum right in its own backyard. Powerhouse Parramatta is opening in late 2026 and it is shaping up to be one of the most significant cultural landmarks this region has ever seen. Here is everything you need to know.
What Is Powerhouse Parramatta?
Powerhouse Parramatta is NSW’s largest museum, sitting on the banks of the Parramatta River on Dharug land. At 30,000 square metres, it is the biggest cultural infrastructure project in Australia since the Sydney Opera House — and the first major state cultural institution ever built in Western Sydney.
The $915 million museum was designed by acclaimed Franco-Japanese architects Moreau Kusunoki alongside Australian firm Genton, and built by Lendlease. Construction began four years ago and the main building is now complete, with exhibition fit-outs underway ahead of the late 2026 opening.
Why Is This Such a Big Deal for Western Sydney?
For a long time, Western Sydney — home to nearly 10% of Australia’s entire population — has lacked the kind of major cultural infrastructure that other parts of Sydney take for granted. Powerhouse Parramatta changes that. This is the first NSW state cultural institution to be permanently based in the region, and it signals a real shift in how the state invests in communities west of the CBD.
Construction alone delivered significant economic benefits, with over 4,000 workers contributing more than 2.7 million hours on site — three quarters of whom were from Western Sydney. More than $329 million in contracts went directly to local businesses. Once open, the museum is expected to welcome around 2 million visitors every year.
What’s Inside? A Breakdown for Families
This is not your standard museum. Powerhouse Parramatta has been designed as a dynamic, evolving institution that brings together art, design, science, technology, education and community. Here is what families can expect:
• Seven large-scale exhibition spaces, including one of the largest column-free spaces in Australia at 18 metres high and over 2,000 square metres
• A cinema and a 600-seat theatre for live performances and screenings
• Learning and digital studios for hands-on experiences
• A rooftop garden with telescopes, a greenhouse, Indigenous plant species and sweeping views across Parramatta to the Sydney CBD
• A restaurant and café
• A 24-hour publicly accessible green domain between the museum and the Parramatta River — open every day for festivals, events and community gatherings for up to 10,000 people
The Lang Walker Family Academy — A Game Changer for Kids
One of the most exciting elements for families is the Lang Walker Family Academy — a dedicated STEM learning hub built into the museum. It offers immersive education programs and overnight residencies for up to 10,000 secondary students from Western Sydney and regional NSW each year, giving kids access to world-class science, technology and cultural experiences they might not otherwise get.
For parents who want their children exposed to hands-on learning in an inspiring environment, this is a genuine point of difference from any other attraction in the region.
The Opening Exhibition: Task Eternal
The first major exhibition to open at Powerhouse Parramatta will be Task Eternal — a large-scale, immersive aerospace exhibition exploring humanity’s enduring quest to defy gravity, take flight and journey into space. Developed in partnership with architectural practice Open, it will be one of the most ambitious aerospace exhibitions ever staged in the world.
Five major international exhibitions are in development for opening, with the full program to be announced later in 2026. Watch the Powerhouse website for updates.
Sustainability: A Museum Built for the Future
Powerhouse Parramatta opens with net-zero emissions from day one — making it the first public building in Australia to achieve a 6 Star Designed rating under the Green Building Council of Australia’s new Green Star Buildings framework. Sustainability is embedded throughout: water harvesting, renewable energy systems, zero-waste exhibition practices and a productive landscape developed in collaboration with First Nations communities through Caring for Country principles.
