Greenhalgh's bronze medallion was presented to winners of the Victorian-based Australian of the Year award for two decades. When the NADC assumed responsibility in 1980, it apparently overlooked the issue of a trophy, so Manning Clark received a framed certificate. For the 1986 award to Dick Smith, the NADC commissioned artist Michael Tracey to produce a more appropriate trophy, which the council described in its journal "Australia Day Update": 'The trophy, symbolising achievement, incorporates a figure holding the Australian flag. The figure is made from steel and the lettering is in pewter.' In the bicentenary year Tracey was asked to cast his trophy in bronze instead of steel.
