| 背面描述 | Central device depicts a kookaburra perched and facing, rendered in slightly thinner relief with a shorter beak compared to the Type 4 design, distinguishing this as the Type 5a variant. The bird is positioned centrally within the square flan, with the country name and denomination inscription arranged around the periphery. The design is characteristic of the experimental Kookaburra penny pattern series produced in 1919 as a proposed replacement for the standard penny design. The plain square field with rounded corners frames the motif cleanly, consistent with the overall aesthetic of this pattern series. |

In 1919, the Australian government was actively exploring a domestically produced coinage to replace its reliance on British-struck pennies. Several pattern designs featuring the kookaburra were commissioned and struck in multiple metals and configurations — this silver example being among the more refined survivors of that experimental series. The kookaburra proposal ultimately failed; Australia returned to the familiar regal penny design, and the bird would not appear on circulating coinage for another decade, finally landing on the 1990 bullion dollar.
