| 背面描述 | The reverse presents an antiqued high-relief composition depicting a world map rendered across the annular field, showing the flight route from England to Australia as a bold engraved line arcing across Europe, the Middle East, and Asia. In the lower field, a detailed depiction of a Vickers Vimy biplane is shown in flight against a stylised sky with radiating sunrays visible at the lower right, evoking the historic 1919 arrival in Darwin. The central aperture again houses the rotating gold-plated propeller insert. The legend CENTENARY OF FIRST FLIGHT arcs along the upper left rim, while ENGLAND TO AUSTRALIA appears along the lower right, all lettered in raised Latin capitals. |

In December 1919, Ross and Keith Smith completed the first England-to-Australia flight, covering roughly 18,000 kilometres from Hounslow Heath to Darwin in just under 28 days to claim the £10,000 prize offered by the Australian government. The antiqued finish on this issue is a deliberate production technique — chemically treated post-strike to accelerate surface oxidation, deepening contrast in the recessed areas of a design pressed at unusually high die pressure.
The 2 oz fine silver format was chosen specifically to accommodate the relief depth without compromising edge detail — a practical minting constraint, not an aesthetic one.
