LEGO PLAY Presents IAC 2025 Space Day

Overview

Ignite your imagination at IAC 2025 Space Day as LEGO PLAY transforms Darling Harbour into a free intergalactic wonderland on Friday, October 3. Inspiring adults and kids alike to look to the stars and beyond, expect a free, family-friendly festival of space exploration and curiosity.

Equipped with myriad building blocks alongside curious characters, ranging from spacewalking astronauts to shape-shifting mutants, guests can spend the day building rovers, shuttles and space stations primed to take a minifig on an interplanetary adventure.

Meanwhile, the program is jam-packed with fascinating encounters. Moonwalk into Martin Place to snap a selfie with a 10-metre-tall inflatable astronaut, then take remote control of Roo-Ver — an Aussie-built rover destined for the lunar surface as part of NASA's Artemis campaign.

There's also the chance to meet and greet astronauts, including Australia's first female astronaut, Katherine Bennell-Pegg, alongside a host of other international space leaders. With loads more to explore, IAC 2025 Space Day is ripe for all things celestial fun.
