A short walk from Darling Harbour, this cavernous science and design museum whirs away inside the former power station for Sydney’s defunct, original tram network. The collection and temporary exhibitions cover everything from robots and life on Mars to steam trains to climate change to atoms to fashion, industrial design and avant-garde art installations. There are great options for kids of all ages but it's equally intriguing for adults. Grab a map of the museum once you're inside. Disabled access is good.
The Powerhouse will be closing in January 2020 and much of the collection will move to a new location in Parramatta, due to open in 2023. This site will be redeveloped as an arts precinct with a design museum, theatre and more.
