| Reverse description | The reverse features a dynamic, pad-printed polychrome composition depicting multiple Humpback Whales in varying scales against a vivid blue ocean field rendered in shades of cerulean and cobalt. A large adult Humpback Whale is shown breaching in the upper centre of the design, its body rising above the water's surface in a naturalistic pose, with fine relief detail highlighting the characteristic tubercles and ventral pleats of the species. Additional whales are depicted swimming beneath the surface in the lower half of the field, conveying a sense of depth and movement. The legend HUMPBACK WHALE arcs along the upper rim, with the designer's initials AWB appearing in the lower field. |

| Additional information |
Australia's humpback whale population collapsed under twentieth-century commercial whaling before the species received federal protection in 1963 — one of the earliest such protections globally. Recovery has been slow but measurable, with east coast populations now estimated above 40,000. The pad-printing process used here applies colour directly to the coin's surface through a silicone transfer method, a technique the RAM has deployed increasingly since the 2010s to sidestep the cost and complexity of enamel inlay.
