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. In 1998, New South Wales was the first state to proclaim a marine emblem, the Eastern Blue Groper (Achoerodus viridis). A species of wrasse, this inquisitive fish grows to a metre in length and inhabits rocky reefs, river estuaries and seagrass beds from southern Queensland to southern Victoria.
