Some expedition brochures of Australia guarantee special perks included in their mission of enabling people to explore the diverse wildlife, plant life and aboriginal heritage of Australia. With promises of exploring the wetlands and aboriginal artwork of tropical Arnhem Land, to sighting Koalas in southern eucalyptus forests, and experiencing where kangaroos, cockatoos, platypus, tree kangaroos and crocodiles all dwell, some expeditions carry a maximum group size of 16, and claim to be suitable for most ages with small lodges and tented camps are provided. So far, only Australia has an accreditation system to rate tour operators and resorts on the basis of their "greenness". However, among all these promises, the question must be asked, "How is the environment and ecosystems of Australia being affected and who is benefiting from this business?" The issue of how ecotourism affects the environment and its native population is important and must be addressed. Environmental damage has already been done worldwide due to forestry, creating farmland, industrialization, etc., and Australia's commitment to conserving the environment while at the same time providing economically for its people (specifically the indigenous Aboriginals) must be examined.
