Queensland's chief harness racing steward David Farquharson has been fired after being on suspension for two months.

Queensland Racing Integrity Commissioner Ross Barnett said Farquharson's employment was terminated as of Friday.

He said Farquharson was suspended in December pending an investigation into a matter reported by a racing industry participant.

"Our decision was made after a thorough and fully independent external investigation was completed," Mr Barnett said.

"I want to ensure the community that the QRIC is committed to upholding the integrity of the racing industry and all complaints are taken seriously and fully investigated."

Barnett said it was not QRIC policy to discuss the matter any further. Farquharson could not be contacted but is understood to be considering his legal position..
