| 背面描述 | The deeply domed reverse depicts a rich and detailed underwater tableau of the Great Barrier Reef, featuring a prominent shark swimming amidst an array of colourful coral formations, sea anemones, and diverse marine flora rendered in high relief with applied colour highlights. A large stylised wave rendered in iridescent colour occupies the centre of the composition, evoking the dynamic and vibrant ecosystem of the reef. The denomination $5 appears in the lower centre field, integrated among coral and sea life motifs. The legend GREAT BARRIER REEF arcs along the upper border, with the date 2022 at the lower left and the motto BEAUTY, RICH & RARE along the lower border. |

| 附加信息 |
The Royal Australian Mint's domed coinage program has pushed technical boundaries since its first curved-planchet issues in the mid-2010s, requiring custom striking equipment and specialized die geometry to achieve consistent relief across a concave and convex surface simultaneously. The Great Barrier Reef subject carries particular urgency given that large-scale coral bleaching events — most severely in 2016, 2017, and 2022, the very year of this strike — have affected over half the reef system.
Ian Rank-Broadley's fifth portrait was replaced for Australian coinage by Jody Clark's sixth portrait in 2019.
