| 背面描述 | A young Leatherback Sea Turtle hatchling depicted in dynamic swimming pose, rendered with naturalistic detail against an open field. Beneath the hatchling appears a stylised shell motif alongside an outline impression of a 20 cent coin. The denomination numeral 20 appears in the field, serving as the principal legend on the reverse. |

The leatherback is the largest turtle species alive, capable of crossing entire ocean basins and diving deeper than most marine mammals — yet its hatchlings face mortality rates that can exceed 99% before reaching adulthood. Australia's north Queensland and northern territory coastlines host nesting sites of genuine conservation significance, and the species' IUCN vulnerable status has driven sustained federal protection efforts since the late 1980s.
