Mountains: Inscribed on the World Heritage List in 2000, the Greater
Blue Mountains just to the west of Sydney consist of more than one million
spectacular hectares of sandstone plateaux, escarpments and gorges dominated
by temperate eucalypt forest. The coin’s reverse depicts the Three Sisters
rock formation from Echo Point in colour. The design includes a Blue
Mountains Tree Frog, an inhabitant of the region’s rocky rivers and streams.
