This medallion cover features limited medallion and corresponding stamp from Marine Emblems stamp issue.

Australia’s states and territories have been given various official emblems, including floral, bird, animal and marine. This issue features the marine emblems of three states. The Leafy Seadragon (Phycodurus eques) was adopted as South Australia’s marine emblem in 2001. Around 24 centimetres in length, this ethereal-looking fish is hard to spot, as it is camouflaged by the long, seaweed-like protrusions growing on its body. Leafy Seadragons can be found along Australia’s southern and western coasts.
