A third case involving allegations of match fixing in Queensland harness racing has been adjourned for a month.

Michael Kevin Grant, of Redcliffe, appeared in the Brisbane Magistrates Court on Friday charged with match fixing.

His case was adjourned until August 30 for further mention and no further details of allegations were told to the court.

Queensland Racing Integrity Commissioner Ross Barnett said a harness racing participant, Grant faced one count of receiving inside information and three counts of possessing tainted property.

"This is the third arrest as a result of a protracted investigation into alleged systematic match fixing in the harness racing industry," Barnett said.

Detectives from the Queensland Racing Crime Squad attached to the Queensland Racing Integrity Commission made their first match fixing arrests in April.

Barnett said on April 7, Warwick man Dayl March, 46, was charged with one count of match fixing and Limestone Ridges man Bart Cockburn, 27, was charged with four counts of match fixing.

Their cases are ongoing.

The QRCS is located within the Queensland Racing Integrity Commission at Albion and is tasked with investigating serious animal cruelty and major and organised crime across all three codes of racing.
