Fraser Island

Fraser Island

Fraser Island lies just off the east coast of Australia. At 122 km long, it is the largest sand island in the world. Majestic remnants of tall rainforest growing on sand and half the world’s perched freshwater dune lakes are found inland from the beach. The combination of shifting sand-dunes, tropical rainforests and lakes makes it an exceptional site.

Île Fraser

Au large de la côte orientale de l’Australie, l’île Fraser, longue de 122 km, est la plus grande île de sable du monde. En arrière de la plage se trouvent des vestiges majestueux de grandes forêts pluviales poussant sur le sable et la moitié des lacs dunaires d’eau douce perchés du monde. Sa combinaison de dunes de sable encore en mouvement, de forêts tropicales humides et de lacs en fait un site exceptionnel.

جزيرة فرايزر

على الساحل الشرقي لأستراليا، تقع جزيرة فرايزر التي يبلغ طولها 122 كيلومتراً وهي الجزيرة الرملية الأكبر في العالم. وراء الشاطئ، نجد بقايا ضخمة لغابات مطر كبيرة تنمو على الرمل ونصف البحيرات العذبة الكثبانية المعلّقة في العالم. ويجعل اجتماع كثبان الرمل المتحركة والغابات الاستوائية الرطبة والبحيرات من هذا الموقع موقعاً استثنائياً.

Остров Фрейзера

Фрейзер, остров длиной 122 км, лежащий вблизи восточного побережья Австралии, является самым большим песчаным островом в мире. Здесь можно увидеть остатки величественных влажных высокоствольных лесов, произрастающих на песках, а также пресноводные «висячие озера», расположенные посреди дюн (половина таких озер в мире приходится именно на остров Фрейзер). Сочетание движущихся песчаных дюн, влажных лесов и «висячих озер» делает это место неповторимым.

Fraser eiland

Fraser Island ligt vlak voor de oostkust van Australië. Met een lengte van 122 kolometer is het het grootste zandeiland ter wereld. Het is een plek van buitengewone schoonheid, met lange ononderbroken witte stranden geflankeerd door gekleurde zandkliffen, majestueus-grote regenwouden en talloze zoetwatermeren met kristalhelder water. De 40 meren vormen de helft van alle zoetwaterduinmeren ter wereld. De meren worden gevormd doordat organisch materiaal - bladeren, schors en dode planten - geleidelijk terechtkomt in door de wind gecreëerde holtes en daarna omhoog komt en uithardt. De hoogste duinen op het eiland lopen op tot 260 meter boven de zeespiegel.

Brief synthesis

Fraser Island, also known by its Aboriginal name of K’gari, lies along the eastern coast of Australia. The property covers 181,851 hectares and includes all of Fraser Island and several small islands off the island's west coast. It is the world’s largest sand island, offering an outstanding example of ongoing biological, hydrological and geomorphological processes.  The development of rainforest vegetation on coastal dune systems at the scale found on Fraser Island is unique, plus the island boasts the world’s largest unconfined aquifer on a sand island.

The property has exceptional natural beauty with over 250 kilometres of clear sandy beaches with long, uninterrupted sweeps of ocean beach, strikingly coloured sand cliffs, and spectacular blowouts. Inland from the beach are majestic remnants of tall rainforest growing on sandy dunes and half of the world’s perched freshwater dune lakes. 

Criterion (vii): Fraser Island is the largest sand island in the world, containing a diverse range of features that are of exceptional natural beauty. The area has over 250 kilometres of clear sandy beaches with long, uninterrupted sweeps of ocean beach, including more than 40 kilometres of strikingly coloured sand cliffs, as well as spectacular blowouts. Inland from the beach are majestic remnants of tall rainforest growing on tall sand dunes, a phenomenon believed to be unique in the world. Half of the world’s perched freshwater dune lakes occur on the island, producing a spectacular and varied landscape. The world’s largest unconfined aquifer on a sand island has also been found here. 

Criterion (viii): The property represents an outstanding example of significant ongoing geological processes including longshore drift. The immense sand dunes are part of the longest and most complete age sequence of coastal dune systems in the world and are still evolving. The superimposition of active parabolic dunes on remnants of older dunes deposited during periods of low sea level, which are stabilised by towering rainforests at elevations of up to 240 metres, is considered unique. Fraser Island also has a variety of freshwater dune lakes which are exceptional in terms of number, diversity and age. The dynamic interrelationship between the coastal dune sand mass, aquifer hydrology and the freshwater dune lakes provides a sequence of lake formation both spatially and temporally.

The process of soil formation on the island is also unique, since as a result of the successive overlaying of dune systems, a chronosequence of podzol development from the younger dune systems on the east to the oldest systems on the west change from rudimentary profiles less than 0.5 metres thick to giant forms more than 25 metres thick. The latter far exceeds known depths of podzols anywhere else in the world and has a direct influence on plant succession, with the older dune systems causing retrogressive succession when the soil horizon becomes too deep to provide nutrition for tall forest species. 

Criterion (ix): The property represents an outstanding example of significant ongoing biological processes. These processes, acting on a sand medium, include biological adaptation (such as unusual rainforest succession), and biological evolution (such as the development of rare and biogeographically significant species of plants and animals).

Vegetation associations and succession represented on Fraser Island display an unusual level of complexity, with major changes in floristic and structural composition occurring over very short distances. Both heathland and closed forest communities provide refugia for relict and disjunct populations, which are important to ongoing speciation and radiation. Evolution and specialised adaptation to low fertility, fire, waterlogging and aridity is continuing in the ancient angiosperm flora of the heathlands and the associated vertebrate and invertebrate fauna. Since listing, patterned fens have been discovered on the property, which along with those at Cooloola, are the only known examples of sub-tropical patterned fens in the world. These fens support an unusual number of rare and threatened invertebrate and vertebrate species.

The dynamic interrelationship between the coastal dune sand mass, hydrology, the ongoing processes of soil formation and the development of plant communities is remarkable in its scale and complexity given the uniform substrate. In particular, the development of rainforest vegetation communities, with trees up to 50 metres tall on coastal dune systems at the scale found on Fraser Island, is not known to occur elsewhere in the world. There is clear zonation and succession of plant communities according to salinity, water table, age and nutrient status of dune sands, exposure and fire frequency. The low shrubby heaths (‘wallum’) are of considerable evolutionary and ecological significance.  Fauna including a number of threatened species of frog, have adapted to the highly specialised acidic environment associated with wet heathlands and sedgelands in this siliceous sand environment.

Integrity

The property includes all of Fraser Island and a number of small adjacent islands off the west coast including Stewart and Dream Islands covering an area of 181,851 hectares. The boundary of the property extends 500 metres seaward from high water mark around Fraser Island and the smaller islands. The majority of Fraser Island is National Park, and all of the marine area within the property lies within Great Sandy Marine Park. A small area of private land on the island is managed to ensure the property’s values are maintained.

The conditions of integrity are met as there is no perceptible human threat to longshore drift and other ongoing processes that make this area outstanding. The property is sufficiently large, diverse and free from disturbance to contain all ecosystem components required for viable populations of all species and for continued maintenance of all natural phenomena. For example the evolution of soil profiles remains essentially undisturbed. Weeds, plant diseases and feral animals are present but in low numbers and are subject to active management. Disjunct and relict populations of flora and fauna, including those associated with the lakes and creeks, have remained intact and will continue to be important for ongoing speciation. While the tall forests have been affected to some extent by logging, this practice has stopped and the forests have the capacity to return to their former grandeur.

Protection and management requirements

On-ground management of the property is the responsibility of the Queensland Parks and Wildlife Service, Department of Environment and Resource Management, guided by the Great Sandy Region Management Plan, and activity-specific management plans for Fraser Island. As the majority of the island is national park, the strongly protective provisions of the Nature Conservation Act 1992 and the Recreation Areas Management Act 2006 apply. The narrow marine zone surrounding the island lies within the Great Sandy Marine Park and is subject to the provisions of the Marine Parks Act 2004. Indigenous, community and scientific advice on protection and management of the World Heritage values is provided to the State of Queensland and Australian Governments by three Fraser Island World Heritage Area Advisory Committees.

Key threats requiring ongoing attention include degradation due to visitor numbers, inappropriate fire, invasive plants and animals, and climate change. Recreational use of the area is intensive and localised degradation can occur from excessive numbers of visitors potentially impacting on, in particular, lake water quality. Appropriate fire management is required to maintain the integrity of the World Heritage values. Significant human and financial resources are being directed to the management of these threats as well as to the protection and monitoring of the property.

Overarching protection of the World Heritage values occurs under national legislation, the Environment Protection and Biodiversity Conservation Act 1999. All World Heritage properties in Australia are ‘matters of national environmental significance’ under that legislation, which is the statutory instrument for implementing Australia’s obligations under the World Heritage Convention. By law, any action that has, will have or is likely to have a significant impact on the World Heritage values of a World Heritage property must be referred to the responsible Minister for consideration. Substantial penalties apply for taking such an action without approval. In 2007, Fraser Island was added to the National Heritage List, in recognition of its national heritage significance under the Act.

Long Description

Fraser Island lies just off the east coast of Australia. Stretching over 120 km along the southern coast of Queensland, Fraser Island is the largest sand island in the world.

It is a place of exceptional beauty, with long uninterrupted white beaches flanked by strikingly coloured sand cliffs, majestic tall rainforests and numerous freshwater lakes of crystal-clear waters.

The massive sand deposits that make up the island are a continuous record of climatic and sea level changes over the past 700,000 years.

Fraser Island features complex dune systems that are still evolving, and an array of dune lakes that is exceptional in its number, diversity and age.

The highest dunes on the island reach up to 260 m above sea level. 40 perched dune lakes can be found on the island. These lakes are formed when organic matter, such as leaves, bark and dead plants, gradually build up and harden in depressions created by the wind.

The island also has several barrage lakes, formed when moving sand dunes block a watercourse, and 'window' lakes, formed when a depression exposes part of the regional water table.

A surprising variety of vegetation types grow on the island, ranging from coastal heath to subtropical rainforests. It is the only place in the world where tall rainforests, up to 50 m high, are found growing on sand dunes at elevations of over 200 m.

Birds are the most abundant form of animal life on the island with over 230 species being recorded. It is a particularly important site for migratory wading birds which use the area as a resting place during their long flights between southern Australia and their breeding grounds in Siberia. A species of particular interest is the endangered ground parrot, which is found in the wallum heath lands.

Few mammal species are present on the island. The most common are bats, particularly flying foxes. The dingo population on the island is regarded as the most pure strain of dingoes remaining in eastern Australia.

The lakes on Fraser Island are poor habitats for fish and other aquatic species because of the purity, acidity and low nutrient levels of the water. Some frog species are adapted to survive in this difficult environment. Appropriately called 'acid frogs', they tolerate the acidic condition characteristic of the Fraser Island lakes and swamps.

The earliest date for the occupation of Fraser Island is currently 1,500-2,000 years. Visible remains of Aboriginal settlement include middens, canoe and gunyah trees, and a few other markings such as scars where bees' nests have been removed. The Badtjala and Kabi Kabi groups of Aboriginal people have cultural and other traditional affiliations with the area. European contact, initiated by Matthew Flinders in 1802, was sporadic and limited to explorers, escaped convicts and shipwreck survivors.

Historical Description

In 1860 Fraser Island was gazetted as an Aboriginal reserve. The reserve was largely revoked two years later following the discovery of valuable stands of timber. The remnant Aboriginal reserve was revoked in 1906, after the Aborigines were removed from Fraser Island. In 1908 the central part of Fraser Island was declared a forestry reserve, and by 1925 most of the island had been set aside as state forest. Fraser Island (Great Sandy National Park) (74,900ha), was gazetted in 1971.

The remainder of Fraser Island consists predominantly of vacant Crown land of 78,404ha in public ownership, which has been proposed as a National Park extension subject to resolution of Aboriginal Land interests. Parts of this have been effectively managed for conservation purposes, and prior to the Commission of Inquiry had been proposed for "preservation zoning" (DASET, 1991; A.Turner, pers.comm., 1992).

The Fraser Island (Great Sandy Region) was accepted as a natural World Heritage Site in 1992, on the basis of criteria (ii) and ( iii ).

Legislation is proposed to cover the whole area nominated, as a regional park (DASET, 1991).
