| 背面描述 | A highly detailed depiction of a Green and Gold Bell Frog (Litoria aurea) perched among crossed reed stems, rendered in high relief against a polished field. The legend 'DISCOVER AUSTRALIA' arcs along the upper periphery, while the inscriptions '2012', 'GREEN & GOLD BELL FROG', '1/25oz', '9999 GOLD', and the Perth Mint 'P' mintmark appear around the lower and lateral borders. The designer's initials 'WR' are visible in the field near the frog. |

The Discover Australia series launched by Perth Mint in 2009 was built around endemic fauna, and the green and gold bell frog earned its place partly through ecological irony: once abundant across southeastern Australia, it had become locally extinct in much of its historical range by the time this coin was struck. The species gained unexpected notoriety in the 1990s when a colony was discovered surviving on the grounds of the Homebush Bay Olympic site in Sydney — delaying construction and triggering federal environmental review.
The 1/25 oz format was Perth's standard entry-level gold denomination for the series, aimed squarely at the collector rather than the bullion buyer.
