Australian police revealed Thursday they had cracked a major global money-laundering ring with operatives in more than 20 countries and funds syphoned off to groups reported to include Hezbollah.
The Australian Crime Commission said more than Aus$580 million (US$512 million) of drugs and assets had been seized, including Aus$26 million in cash, in a year-long sting codenamed Eligo targeting the offshore laundering of funds generated by outlaw motorcycle gangs, people-smugglers and others.
According to the ACC, the operation had disrupted 18 serious and organised crime groups and singled out 128 individuals of interest in more than 20 countries, tapping information from agencies including the United States Drug Enforcement Administration.
The full details of which countries had been involved were not revealed but acting ACC chief Paul Jevtovic said "the reality is that the Middle East and Southeast Asia have featured prominently".
"Drug importations into Australia continue to be the main profit source by organised crime here in this country, but there is a range of other things, serious organised investment frauds, identity theft," Jevtovic said.
Eligo saw 105 people arrested on 190 separate charges and resulted in the closure of three major clandestine methamphetamine labs and Australia's largest-ever urban hydroponic cannabis hothouse in Sydney last November.
It was described as "one of the most successful money-laundering investigations in Australian law enforcement history" by the ACC.
"The task force focused on high-threat money-laundering activities and, as a result, revealed a range of different crime types which has led to these extraordinary outcomes," said Australia's Justice Minister Michael Keenan.
"Seizing more than $550 million worth of drugs and cash is a significant blow to the criminal economy," he added.
Legitimate international cash wiring services were a major focus of the operation, with the government's anti-laundering agency AUSTRAC saying they had been identified as at "high risk of being exploited by serious and organised crime groups".
A Fairfax media expose on the operation found criminals targeted foreign nationals and students in Australia awaiting remittances from overseas, hijacking the transaction by depositing dirty money to the payee and then taking the cash wired from offshore.
Fairfax said at least one of the exchange houses used in the Middle East and Asia delivered a cut from every dollar it laundered to Lebanon's powerful Shiite movement and Syria ally Hezbollah, which is banned as a terrorist organisation in Australia.
"It was just never-ending," said ACC acting chief Col Blanch. "We were regularly finding bags of $500,000 and $400,000."
Eligo netted a record Aus$5.7 million single cash seizure in Sydney at the weekend -- seven suitcases stuffed with bills uncovered in an apartment near the city's airport.
A 58-year-old US citizen who recently arrived in Australia via Costa Rica has been charged with dealing with the proceeds of crime over the stash.
"This is one of Australia's largest cash seizures," said federal police commissioner Tony Negus.
The ACC is also monitoring the use of Bitcoin, a so-called virtual crypto-currency generated by a complex computer algorithm.
Bitcoin made headlines last year when US authorities closed the Silk Road website after the currency was found being used to buy illegal drugs, forged documents, hacker tools and even the services of hitmen.
Organised crime is estimated to cost Australia Aus$10-15 billion per year by the ACC, with drugs, money-laundering, fraud, firearms and high-tech cyber offences the major issues.
Profits from transnational organised crime were estimated at US$870 billion in 2009 -- the latest available data -- according to the ACC's 2013 report into the sector. That represented about 1.5 percent of global GDP at the time.
