| Reverse description | The reverse depicts a stylised representation of the solar corona during a total eclipse, shown as a radiant disc positioned above an outline map of the Australian continent. Surrounding the central design are concentric distorted circular and radial lines evoking the curvature of light predicted by Einstein's general theory of relativity, a visual reference to the 1922 Wallal solar eclipse expedition that provided crucial confirmation of that theory. The inscriptions in the field read WALLAL CENTENARY and AUSTRALIA TESTS EINSTEIN'S THEORY, commemorating the centenary of the landmark astronomical observation conducted at Wallal Downs, Western Australia. |
