Australia is primarily battling water and air pollution caused by mining and oil spills. While the country does not currently have nuclear power plants, mining activities related to uranium extraction can contribute to environmental contamination. Additionally, oil spills, either from accidents involving oil tankers or offshore drilling operations, pose significant threats to Australia's marine ecosystems. Pesticide usage is also a concern, but it is not one of the main contributors to water and air pollution in the country.
