FOUR people were convicted last year of money laundering totalling $1.6 million.
The convictions bring to six the number of tried cases in the country since 2005.
The Financial Intelligence Unit said in its 2011 annual report the four were between the ages of 25 years and 30 years at the time of the offences dating as far back as 2005.
The youngest person implicated, an Australian, was 25 years old at the time of the offence while the oldest was a 30 years old.
The largest sum involved in an individual case was $840,000, while the lowest was $90,930.
The longest sentence meted by the High Court for the offence was seven years in a case involving a woman.
