The colourful theme for the Australia Pavilion, which became synonymous with the hosting of the Expo with Australia as host nation, was designed by prominent Australian artist Ken Done, and featured huge playful colourful letters making up the word Australia in an Australia Pavilion Entrance set, and Exit set, with the entrance set a stack of nine, 3x3, some 2.1 metres high each, and the exit set, in a line of nine letters, some 5.6 metres high each. These letters became a very popular photo opportunity for the Expo, and the theme was also found on the brightly coloured Australia Pavilion uniforms also.
