Geographical bases:

Australia is a vast continent located in the southern hemisphere, surrounded by the Indian Ocean and the Pacific Ocean.

Other information:

• Great Barrier Reef: one of the best-known natural places in the world, it is located off the coast of Queensland.
• Unique flora and fauna: Australia is famous for its unique flora and fauna in the world.
• Outback Desert: most of Australia's interior consists of it, a vast, arid plateau with spectacular landscapes, rock formations and unique wildlife.

The Great Barrier Reef

Location lies off the north-eastern coast of Australia. It is the largest coral reef system in the world, stretching over 2,300 kilometres. Known for its extraordinary biodiversity. It is home to a wide range of marine species, including numerous types of coral, fish, molluscs, sharks, rays, and many others.

Water pollution: it is caused by chemical discharges, etc. These pollutants can directly damage corals, compromise water quality and encourage the growth of harmful algae.

Climate change: it is the main threat that causes coral bleaching which can weaken it and make it more susceptible to diseases.

The Great Barrier Reef is threatened by various forms of pollution, and this is a major concern for its long-term health.

The wildlife:

Australia is home to extraordinarily diverse wildlife, with many unique species found nowhere else in the world.

1. Marsupials: Australia is famous for its marsupials, mammals that carry their young in a ventral pouch. Among the best-known marsupials are kangaroos, koalas, wallabies, wombats and numbats.
2. Monotremes: the only egg-laying mammals in the world are monotremes, and Australia is home to two species: the platypus and the echidna.
3. Reptiles: Among Australian reptiles, there are various species of venomous snakes, lizards, land and freshwater turtles, as well as the goanna, a large predatory lizard.

Invasion of non-native species: Accidental or deliberate introduction of non-native species can threaten the native fauna. These invasive species can compete for resources such as food and living space, transmit disease, or directly prey on native species.

Forest fires: In recent years there have been extremely intense and destructive fires. These fires have caused the loss of critical habitats for many animal species, leading to serious threats to wildlife.

Wildlife in Australia has faced various challenges and threats over the years. Some of the major problems include:

Outback desert:

It is a vast region of Australia that extends thousands of kilometers into the continent. Often associated with arid deserts, the Outback is actually a very differt area, including deserts, plains, mountains, forests and rivers.

1. Extent: The Outback covers approximately 70% of Australia's territory, but is sparsely populated due to its extreme environmental conditions.
2. Climate: The Outback is known for its arid and variable climate. Temperatures can be extreme, with very hot summers and cold winters. Rainfall is often limited, and many areas of the Outback are classified as desert.
3. Natural Resources: The Outback is rich in natural resources, including minerals, natural gas, and coal. The mining industry is present in several parts of the Outback, but this has also led to debates about sustainable resource management.
