| 背面描述 | A standing male figure in work attire is depicted beside a large bucket wheel excavator, a piece of heavy industrial mining equipment used in open-cut mining operations. The design celebrates the Australian mining industry, rendered in a bold, illustrative style with strong compositional emphasis on the machinery. The denomination 20 and the inscription AUSTRALIAN MINING appear in the field, integrating the lettering into the overall industrial theme. |

Part of the Royal Australian Mint's ongoing themed circulation series, this 20-cent issue commemorates the mining industry at a moment when Australia's resources boom — driven largely by Chinese demand for iron ore and coal — was already beginning to cool after a decade of record export revenues. The Pilbara and Hunter Valley operations that defined that era were generating roughly 19% of GDP at the boom's peak in the early 2010s.
