Australia Post has released a stamp issue entitled Wilderness Australia. The stamps feature Nullarbor Plain, Daintree National Park and Cradle Mountain.
The vast Nullarbor Plain, located on the Great Australian Bight coast, is the world's largest limestone karst landscape covering an area of 270,000 square kilometres, extending 2,000 kilometres between Norseman and Ceduna. Two thirds of the Nullarbor is within Western Australia and one third is in South Australia. The name Nullarbor derives from "no trees", but the plain is covered with bluebush and saltbush plants, hardy shrubs that are drought-resistant and salt-tolerant. Historically, the Nullarbor was used by the semi-nomadic Spinifex Wangai people.
The Daintree National Park, north of Cairns, is made up of two sections - Mossman Gorge and the Cape tribulation - and is part of the traditional lands of the Eastern Kuku Yalanji people. Much of the Mossman Gorge section is covered in tall, dense rainforest and supports a range of habitats and a diverse assortment of wildlife.
Cradle Mountain forms the northern end of the wild Cradle Mt - Lake St Clair National Park, part of the Tasmanian Wilderness World Heritage Area, covering approximately 1.38 million hectares (or about 3.46 million acres) and encompassing more than 20 per cent of Tasmania. It is one of the last true wilderness regions on Earth. Aboriginal use of the Cradle Mountain area dates from 10,000 years ago. The area ranges from rainforest to grassland, containing ancient plants and a diversity of animals.
