Julian Assange has arrived in Australia after walking free from an American court following a deal with US authorities.
He pleaded guilty to one criminal charge under the deal after fighting against extradition to the US, where he was accused of disclosing military secrets.
What did Julian Assange do?
Mr Assange ran Wikileaks, a website that published many confidential or restricted official reports related to war, spying and corruption.
In 2010, it released a video from a US military helicopter which showed civilians being killed in the Iraqi capital Baghdad.
