139 AUSTRALIA - Greater Blue Mountains Area (UNESCO)

The Greater Blue Mountains Area consists of 1.03 million hectares of sandstone plateaux, escarpments and gorges dominated by temperate eucalypt forest. The site, comprising eight protected areas, is noted for its representation of the evolutionary adaptation and diversification of the eucalypts in post-Gondwana isolation on the Australian continent. There are 91 eucalypt taxa within the Greater Blue Mountains Area, which is also outstanding for its exceptional expression of the structural and ecological diversity of the eucalypts associated with its wide range of habitats. The site provides significant representation of Australia's biodiversity with 10% of the vascular flora as well as significant numbers of rare or threatened species, including endemic and evolutionary relict species, such as the Wollemi pine, which have persisted in highly-restricted microsites. The Greater Blue Mountains Area consists of mostly forested landscape on a sandstone plateau inland from central Sydney, New South Wales. The property, which includes eight protected areas in two blocks separated by a transportation and urban development corridor, is made up of seven national parks as well as the Jenolan Caves Karst Conservation Reserve. These are the Blue Mountains, Wollemi, Yengo, Nattai, Kanangra-Boyd, Gardens of Stone and Thirlmere Lakes National Parks.

The area does not contain mountains in the conventional sense but is described as a deeply incised sandstone plateau rising from less than 100 m above sea level to 1,300 m at the highest point. There are basalt outcrops on the higher ridges. This plateau is thought to have enabled the survival of a rich diversity of plant and animal life by providing a refuge from climatic changes during recent geological history.  It is particularly noted for its wide and balanced representation of eucalypt habitats from wet and dry sclerophyll, mallee heathlands, as well as localized swamps, wetlands and grassland. There are 91 species of eucalypt (13% of the global total) in the Greater Blue Mountains Area, 12 of which are believed to occur only in the Sydney sandstone region. In addition to its rich diversity of eucalypts, the Area also contains ancient, relict species of global significance. The most famous of these is the recently discovered Wollemi pine, a 'living fossil' dating back to the age of the dinosaurs. Thought to have been extinct for millions of years, the few surviving trees of this ancient species are known only from three small populations located in remote, inaccessible gorges within the nominated property. The Wollemi pine is one of the World's rarest species. More than 400 different kinds of animals live within the rugged gorges and tablelands of the Greater Blue Mountains Area. These include threatened or rare species of conservation significance, such as the spotted-tailed quoll, the koala, the yellow-bellied glider and the long-nosed potoroo, as well as rare reptiles including the green and golden bell frog and the Blue Mountains water skink.

124 AUSTRALIA - Sydney Opera House (WHS)

A major cultural centre for Sydney and its siting at Bennelong Point had been discussed since the 1940s. In 1956 the New South Wales Government called an open-ended international design competition and appointed an independent jury, rather than commissioning a local firm. The competition brief provided broad specifications to attract the best design talent in the world; it did not specify design parameters or set a cost limit. The main requirement of the competition brief was a design for a dual function building with two performance halls. The competition generated enormous interest in Australia and overseas. The New South Wales Government’s decision to commission Jørn Utzon as the sole architect was unexpected, bold and visionary. There was scepticism as to whether the structure could be built given Utzon’s limited experience, the rudimentary and unique design concept and the absence of any engineering advice. The competition drawings were largely diagrammatic, the design had not been fully costed and neither Utzon nor the jury had consulted a structural engineer. Utzon’s design concept included unprecedented architectural forms and demanded solutions that required new technologies and materials. The New South Wales Government also faced public pressure to select an Australian architect. The Sydney Opera House is often thought of as being constructed in three stages and this is useful in understanding the history of the three key elements of its architectural composition: the podium (stage 1: 1958–1961), the vaulted shells (stage 2: 1962–1967) and the glass walls and interiors (stage 3: 1967–1973). Architect Jørn Utzon conceived the overall design and supervised the construction of the podium and the vaulted shells. The glass walls and interiors were designed and their construction supervised by architect Peter Hall supported by Lionel Todd and David Littlemore in conjunction with the then New South Wales Government Architect, Ted Farmer. Peter Hall was in conversation with Utzon on various aspects of the design for at least eighteen months following his departure. Ove Arup & Partners provided the engineering expertise for all three stages of construction.

Design and construction were closely intertwined. Utzon’s unique design together with his radical approach to the construction of the building fostered an exceptional collaborative and innovative environment. His collaborative model marked a break from conventional architectural practice at the time. The design solution and construction of the shell structure took eight years to complete and the development of the special ceramic tiles for the shells took over three years. The Sydney Opera House became a testing laboratory and a vast, open-air pre-casting factory. The Sydney Opera House took sixteen years to build; this was six years longer than scheduled and ten times more than its original estimated cost. On 20 October 1973 the Sydney Opera House was officially opened by Queen Elizabeth II. After inauguration, new works were undertaken over time. Between 1986 and 1988 the land approach and forecourt were reconstructed and the lower concourse developed under the supervision of the then New South Wales Government Architect, Andrew Andersons, with contributions by Peter Hall. Between 1998 and 1999 the recording and rehearsal room was converted into two areas: an assembly area for the orchestra and the Studio, a revitalised performance space for the presentation of innovative music and performing arts. In 1998, in accordance with the celebration of the 25th anniversary of inauguration, the Sydney Opera House Trust appointed Sydney architect Richard Johnson to advise on future development of the site and to establish planning principles. Through Johnson, the Sydney Opera House Trust began negotiations to reconcile with Utzon and to re-engage him with the building in an advisory capacity. In 1999 Utzon formally accepted Premier Carr’s invitation to re-engage with the project by setting down design principles that outline his vision for the building and explain the principles behind his design. Over three years he worked with his architect son and business partner, Jan Utzon, and Richard Johnson to draw up his design principles for the Sydney Opera House, including the refurbishment of the reception hall, construction of the western loggia, exploration of options for improving the Concert Hall acoustics, improving services to the forecourt to support performances, modification of the orchestra pit and interior of the Opera Theatre. In 2002 The Sydney Opera House Trust released the Utzon Design Principles. In 2004 refurbishment of the Utzon Room (formerly known as the reception hall) was completed.

031 AUSTRALIA - Ningaloo Coast (WHS)

Ningaloo Reef is a fringing coral reef located off the north west coast of Western Australia, approximately 1200 km north of Perth. The reef is 260 km long and is Australia's largest fringing coral reef and the only large reef positioned very close to a landmass. It is known for its seasonal feeding concentrations of the whale shark and the conservation debate surrounding its potential tourism development. In 1987 the reef and surrounding waters were designated as the Ningaloo Marine Park.

Although most famed for its whale sharks which feed there during March to June, the reef also rich in coral and other marine life. During the winter months, the reef is part of the migratory routes for dolphins, dugongs, manta rays and humpback whales. The beaches of the reef are an important breeding ground of the loggerhead, green and hawksbill turtles. They also depend on the reef for nesting and food. The Ningaloo supports an abundance of fish (500 species), corals (300 species), molluscs (600 species) and many other marine invertebrates. The reef is less than half a kilometre offshore in some ares. In 2006, researches from the Australian Institute of Marine Science discovered in the marine park's deeper waters gardens of sponges that are thought to be species completely new to science.
