Australian Pavilion, Osaka Expo 2025

The striking concept design for the Australia Pavilion at Expo 2025 in Osaka is an expression of Australia's warmth, energy and optimism, and of our diverse landscape.

Buchan’s pavilion and exhibition design harnesses Australia’s unique, natural beauty as a canvas for sharing our stories and culture.

The pavilion’s form is an abstraction of a eucalyptus gumnut. The ubiquitous eucalyptus tree, with its myriad shapes and colours, is symbolic of the diversity and resilience of Australian people. In and around the pavilion, the colours of the eucalypts and their gum blossoms will reflect the vibrancy of contemporary Australian society.

The perspectives, experiences and interests of Indigenous Australians are integral to the narrative informing the design. Indigenous cultural advisor Karrda is working with the design team to embed Country into the pavilion, amplifying Indigenous culture, connection to land and water, and ways of knowing.

Taking visitors on an immersive, sensory journey, the exhibition will chase the sun across the land and water, moving from day to night and between real and surreal. Visitors will engage with Australia’s physical beauty whilst learning about our culture and achievements.

The architecture is guided by sustainable design principles, materials and delivery methodology.
