Four men and two women have been arrested and charged on the Gold Coast for their alleged involvement in so-called boiler room scams.
Police allege the group was involved in syndicates that cold call victims and pressure them into handing over cash for fraudulent investment schemes.
Two of the six accused have previously been charged with aggravated fraud and money laundering, from an earlier part of the investigation.
A further two have previously been charged with aggravated fraud.
The arrests follow a two year probe into organised crime in the region.
