Mokbel built and controlled a drug manufacturing and trafficking empire that turned over tens of millions of dollars from the mid-1990s until 2007.
In 2006 he fled a drug trial a few days before it was due to finish to hide out in a farmhouse in the Victorian country town of Bonnie Doon, before taking a yacht from Western Australia to Greece.
Mokbel was eventually arrested at an Athens cafe in June 2007, wearing a wig.
At a pre-sentence hearing in May, Justice Simon Whelan described him as "absolutely incorrigible".
Mokbel expressed remorse through forensic psychologist Wendy Northey.
"I have a lot of making up to do," he told Northey during one of their recent sessions.
"I won't be going anywhere near drugs again."
Mokbel said he felt "saddened by it" and recognised drug dealing caused damage to "a lot of people".
Prosecutor Peter Kidd, SC, did not accept the submission, saying it flew in the face of Mokbel's history of persistent and calculated drug-related offending.
"The matters for which he now purports to express concern and remorse would have been obvious to him at all times during the course of his protracted offending," he said.
Whelan will hear some final submissions from lawyers today before sentencing Mokbel at a time to be fixed.
