Former Bundaberg doctor Jayant Patel is due to be sentenced on Thursday for fraudulently working as a surgeon in Queensland.
The 63-year-old pleaded guilty to four counts of fraud in the Brisbane District Court last Friday.
All criminal negligence charges against him were dropped on the same day after the state's Director of Public Prosecutions decided further trials weren't in the public interest.
Patel was extradited to Australia from his home country the US in 2008 to face allegations of killing and maiming patients while he was a director of surgery at the Bundaberg Base Hospital between 2003 and 2005.
In 2010 he faced trial charged with three counts of manslaughter and one of grievous bodily harm and was convicted on all charges.
The Indian-born surgeon was sentenced to seven years' prison but the convictions were quashed by the High Court in 2012. He was released and separate retrials were ordered.
Patel was acquitted of manslaughter in the first retrial in 2013 and in October the jury in his grievous bodily harm trial was unable to reach a verdict.
He was formally discharged from the criminal negligence charges last Friday.
At the same time he pleaded guilty to dishonestly gaining registration as a medical practitioner in Queensland in 2003 and 2004.
He also pleaded guilty to dishonestly gaining employment at Bundaberg between March 2003 and April 2005.
