Former Bundaberg surgeon Jayant Patel has been barred from ever practising medicine again in Australia.

Queensland's Civil and Administrative Tribunal handed down its judgment this morning, finding Dr Patel lied to be registered in Queensland and concealed matters which questioned his suitability.

Judge Alexander Horneman-Wren said he must never be registered as a practitioner in the medical health profession.

Judge Horneman-Wren said Dr Patel's competence to perform complex surgeries had been found to be lacking.

Dr Patel served time in prison for killing three patients at Bundaberg Hospital but won a High Court challenge against his conviction and was released from jail in 2012.

The Medical Board of Australia and the Health Practitioner Regulation Agency brought disciplinary action against him after all criminal proceedings had finished.

They argued he lied to be registered as a doctor in Bundaberg in 2003, and performed surgeries he knew he was not competent to do.

Dr Patel did not attend the hearing.

The Medical Board of Australia said it will advise international medical regulators about the findings against Dr Patel.

The board said the findings will also be on the public record and accessible to all regulators to whom Dr Patel may apply for registration.

Disciplinary action against Dr Patel began in 2005 and the board said it is now pleased the matter is closed.

Former Bundaberg surgeon faced long series of trials

In 2010, the High Court ruled there was a miscarriage of justice in the way Dr Patel was tried for three counts of manslaughter and another count of grievous bodily harm.

This meant the Queensland jury had heard evidence which prejudiced the case.

The High Court ordered Dr Patel be re-tried, saying he had carried out surgery on patients, who later died, "competently enough".

Separate trials were ordered for each of the charges and in March 2013 Dr Patel was found not guilty of manslaughter in the first of these trials involving the death of Mervyn Morris.

In October 2013, a jury failed to reach a verdict in the second trial on the charge of causing grievous bodily harm to patient Ian Vowles.

In November 2013, Dr Patel pleaded guilty to four counts of fraud in relation to dishonestly obtaining registration and employment in Queensland.

He was sentenced to two years in jail for fraud, wholly suspended.

Queensland's Director of Public Prosecutions decided not to pursue any other charges.
