The ABC takes a look at the main players alleged to be behind a conspiracy to defraud the Australian Tax Office (ATO) of $165 million.
A 10th person was arrested on May 18 and charged in relation to the alleged conspiracy to defraud the Commonwealth of taxation revenue, and he and several others remain on bail.
Who’s who of the alleged tax fraud
Six of those charged — including Adam and Lauren Cranston — face a maximum of 10 years in prison.
But prosecutors agreed they could return home after meeting bail conditions because it will take months to sort out the maze of trusts and companies behind the alleged conspiracy.
Michael Cranston has been suspended from his role as the deputy commissioner of taxation at the ATO.
Unlike his son, he is not being treated as one of the conspirators.
