The Australia Pavilion at World Expo 2025 Osaka, designed by Buchan, embodies the theme 'Chasing the Sun' and is inspired by the ubiquitous eucalypt and gumnut. Found across Australia, the eucalypt's many shapes and colours symbolise the diversity and resilience of the Australian people, reflecting the World Expo theme 'Designing Future Society for Our Lives'. The Pavilion's bold arc and ribbed facade takes its cue from a gumnut bursting into flower – a powerful symbol of new life and the boundless potential of future generations. Beneath the arc, a landscaped Cultural Precinct with yarning circle and sheltered stage creates a gathering place for performance and cultural exchange. Built on circular economy principles, the temporary structure is designed as a canvas for Australia's stories and connection. Inside, a sensory bushwalk immerses visitors in the sights, sounds and feel of being on Country, inviting connection with the continuous living culture of Indigenous Australians.
The Australia Pavilion’s design by Buchan enhanced the way our team operated and engaged with global audiences during World Expo 2025 Osaka. Its open, flowing architecture supported visitor movement, enabling us to welcome millions while maintaining operational efficiency. The pavilion’s flexible spaces accommodated cultural programming, diplomatic engagements and industry events, allowing us to showcase Australia’s creativity, innovation and hospitality at scale. Buchan’s design thoughtfully integrated functionality with a strong national narrative, creating an environment that supported staff capability, enriched the visitor experience and strengthened Australia’s presence on the world stage.
