Environmental issues in Australia describes a number of environmental issues which affect the environment of Australia and are the primary concern of the environmental movement in Australia.
There are a range of such issues, some of the relating to conservation in Australia. Others, for example the deteriorating state of Murray-Darling Basin, have a direct and serious effect on human land use and the economy. Many human activities including the use of natural resources have a direct impact on the Australian environment and its ecology. Additionally Aboriginal culture has a strong connection to the land, with some landscape features considered sacred, and as such environmental damage to Australian Aboriginal sacred sites can also have significant cultural repercussions.
Some of the key issues include: Climate Change; Contamination and Pollution; Ozone Depletion; Conservation; Invasive Species; Land Degradation; Waterway health; Urbanisation and Mining Issues among others.
