The Queensland Racing Integrity Commission has moved to streamline the process for thoroughbred, harness and greyhound trainers to renew their licences.

Racing Minister Stirling Hinchliffe said the changes from the previous annual licensing system were a win for Queensland trainers.

"Instead of renewing their licences each year, Queensland trainers will hold a licence for a period of three years before they're required to renew," he said.

"In addition to this extended licence period, thoroughbred trainer licence categories have been simplified to assist in the licensing and renewal process."

QRIC Commissioner Ross Barnett said the changes were being implemented after consultation with the industry and a year-long trial of three-year licensing for stable hands and kennel attendants.

"The consultation period resulted in mostly positive feedback from trainers who told us they're happy the administrative burden of licensing would be reduced by this change," he said.
