After a good few years in the works (and a fair dose of controversy), Powerhouse Parramatta is officially opening its doors later this spring – and it’s kicking things off with a 23-day festival packed with 179 events. Running from November 7 to 29, the Opening Festival will take over the new museum across four weekends, with a stacked program covering everything from space and science to First Nations culture, design, music, film and food.
