Australia's pavilion will offer visitors a close look at the country's unique landscape and indigenous heritage.

Inspired by the eucalyptus tree and its flowering blossoms, the pavilion's design incorporates innovative and sustainable construction techniques.

There will also be Australian performing arts, sports, science demonstrations, and live entertainment. Two mascots -- Ruby the kangaroo and Coco the koala -- will welcome guests.

Its cafe will offer authentic Australian treats, such as meat pies and lamingtons, alongside the country's world-famous coffee.
