Gold Coast 2018 Commonwealth Games Medal
For many generations the Gold Coast coastline has been a place for gathering, meeting and sport. The Medal design represents the soft sand lines which shift with every tide and wave and is symbolic of athletic achievement. As the water moves towards low tide, each wave moves the sand, creating and leaving behind new lines in the sand witnessed by those present.
The continual change of tide represents the evolution in Athletes who are making their mark. Records are made and special moments of elation celebrated. Although the moment in time may be fleeting, it is forever marked within the shells that are brought upon its tidelines.
