#204 Australia...Thanks John!

The 55c stamp is from 1981 Fungi issue showing Armillaria luteobubalina,known as the Australian honey fungus, which is a species of mushroom in the Physalacriaceae family. Found predominantly in southern Australia, the fungus is responsible for a disease known as Armillaria root rot, a primary cause of Eucalyptus tree death and forest dieback.

The $1.45 stamp was issued in 2003 commemorating 100 years of Australia High Court.

The High Court of Australia is the highest court in the Australian court hierarchy and the final court of appeal in Australia. It has both original and appellate jurisdiction, has the power of judicial review over laws passed by the Parliament of Australia and the parliaments of the States, and interprets the Constitution of Australia. The High Court is mandated by section 71 of the Constitution, which vests in it the judicial power of the Commonwealth of Australia. The High Court was constituted by the Judiciary Act 1903. The High Court of Australia is located in Canberra, Australian Capital Territory.

The 25c stamp was issued in 2006 showing Short-Beaked Echidna.

The Short-beaked Echidna (Tachyglossus aculeatus), also known as the Spiny Anteater because of its diet of ants and termites, is one of four living species of echidna and the only member of the genus Tachyglossus. The Short-beaked Echidna is covered in fur and spines and has a distinctive snout and a specialized tongue, which it uses to catch its prey at a great speed. Like the other extant monotremes, the Short-beaked Echidna lays eggs; the monotremes are the only group of mammals to do so.

The species is found throughout Australia, where it is the most widespread native mammal, and in coastal and highland regions of southwestern New Guinea. It is not threatened with extinction, but human activities, such as hunting, habitat destruction, and the introduction of foreign predatory species and parasites, have reduced the distribution of the Short-beaked Echidna in Australia.

The 45c stamp is from 1995 Centenary of Cinema issue showing the poster of Strictly Ballroom,which was screened in the Un Certain Regard section at the 1992 Cannes Film Festival, winning the "Award of the Youth" prize in the foreign film category.
