Digital currency exchanges in Australia are now obligated to register with AUSTRAC, the country’s financial intelligence unit that is mandated to observe and collect data on domestic businesses with the intent of uncovering money laundering and counter-terrorism operations; AUSTRAC shares its findings with over 40 Australian agencies. As of 3 April 2018 digital currency exchanges must comply with federal Anti-Money Laundering (AML) and Counter-Terrorism Financing (CTF) regulations and businesses must register with AUSTRAC by 18 May 2018.
