Sovereign Yidindji Government

The Sovereign Yidindji Government or Yidindji Tribal Nation is an Aboriginal Australian micro-nation that claims to exercise Australian Aboriginal sovereignty. Led by Murrumu Walubara Yidindji, members of the Yidindji nation renounced legal ties with Australia in 2014. The land they claim lies in the state of Queensland and stretches "south of Port Douglas, through Cairns, inland across the Atherton Tablelands and 80 km out to sea”. The chief minister is Gudju Gudju Gimuybara, while Murrumu is foreign affairs and trade minister.

The Yidindji government is hoping to enter into a memorandum of understanding with the Commonwealth of Australia. It is also "reaching out to countries like Russia and Venezuela to establish diplomatic relations". The Yidindji nation has its own driver licensing system. Murrumu was charged by the Queensland Police Service in May 2015 after being caught with a license and registration plates issued by the Yidindji government and not by the Queensland government. Murruma claimed that the Queensland police has no jurisdiction over him.

In 2022 the micro-nation launched the 'Sovereign Yidindji Dollar', a central bank digital currency pegged to the Australian dollar and claimed to be backed by gold and silver bars.
