These 'platypus' print briefs were based on the design created by Gloria Smythe (Mortimer-Dunn) for the Australian women's Olympic swimming team in 1988. They have a white nylon cord drawstring waist with a green gauze gusset and green seams. On the left hip is a printed yellow panel with the Australian Olympic shield.
The fabric features an all over print of yellow stylised platypuses on a dark green background, with the text 'Australia' in white. This print was chosen instead of the original design of water creatures inspired by Aboriginal rock carvings. The background of the Mabo native title land rights case in 1988 led the committee to decide that the inclusion of Indigenous motifs would be too controversial.
