Climate Emergency is being declared in Australia similarly to many other jurisdictions across the world (actions known as Climate emergency declaration). One such jurisdiction in Australia, Darebin City Council, was the first one in the world to declare a climate emergency in 2016. This page lists all known climate emergency declarations within Australian jurisdictions across all three levels of government in Australia (Local, State, and Federal).

There is currently no declaration of a climate emergency at the Federal level in Australia, although there have been multiple motions moved to declare one.

In October 2019, the Australian Labor Party supported the Australian Greens Party's motion to declare a climate emergency. The motion was additionally supported by crossbenchers Zali Steggall, Helen Haines, and Andrew Wilkie, as well as Centre Alliance. However, the proposition failed with members of the Morrison Government and some crossbenchers voting against it.

The Australian Capital Territory is the first and only territory to have declared a climate emergency. The South Australian Parliament voted for a climate emergency in the upper house and lower house in South Australia.

In June 2019, Councillor Trent McCarthy of the City of Darebin brought together councillors and parliamentarians in Australia and around the world in online link-ups to facilitate collaboration between councils and governments which have declared a climate emergency. Following these link-ups and a successful motion at the National General Assembly of Local Government, McCarthy announced the formation of Climate Emergency Australia, a new network of Australian governments and councils advocating for an emergency response to climate change.

Local government has been the most active level of government in declaring a climate emergency in Australia. Currently, every state in Australia has at least one local government jurisdiction that has declared a climate emergency. Only two capital city local governments have not declared a climate emergency: the City of Perth, which has not yet voted on a climate emergency declaration, and the City of Brisbane, which has voted against a motion to declare a climate emergency. Below is a list of local governments, showing which have declared a climate emergency, which have voted against a climate emergency, and which have not voted on a climate emergency.

36 of 128 local government jurisdictions in NSW have declared a climate emergency, the highest number of any state, although Victoria has the highest percentage of councils that have declared a climate emergency.

Only one local government jurisdiction in the Northern Territory has declared a climate emergency, and that is the City of Darwin.
