Racing industry participants in Queensland have held a rally to protest against proposed changes to the sport's organisational structure.

Around 1000 breeders, owners, trainers, jockeys and bookmakers from across the state attended the two-hour meeting at Doomben racecourse on Wednesday when they also opposed a decision by the state government and Racing Queensland to cut $18.8 million in prize money.

Racing Queensland is currently being run without a board and has an interim chairman in John Muir and an interim chief executive officer in Ian Hall.

A proposal put forward for a new seven-member board to be made up of four non-racing people and one representative from each of the three codes of racing has also been opposed by those at the rally.

The plan is due to be debated in parliament in March but industry participants have called on the government to scrap the idea.

Instead, there was a unanimous call for the government to appoint a board under the current scheme and for that board to hold off making changes until a review was conducted.

State opposition leader Lawrence Springborg, Brisbane Lord Mayor Graham Quirk, and Katter Party state member Shane Knuth were all in attendance at Doomben.

However, rally convenor Ian McCauley said politics should not play a part in the event.

He said Queensland premier Annastacia Palaszczuk and racing minister Grace Grace had both been invited but declined.

"We are racing people. (But) for too long there have been shadowy figures in the corridors of parliament house making decisions," McCauley said.

Leading trainer Rob Heathcote said the confidence he had shown by spending $700,000 on yearlings this year had been eroded by recent decisions.

He said the industry should revert to the former model where gallops, greyhounds and harness racing had their own administration.

Breeder Basil Nolan said the recent sustainability plan released by the state government had no long-term future for racing.

"There has been $70,000 a Saturday ripped from prize money in the metropolitan area alone," Nolan said.

"At the same time we can get no-one to give us exact figures on RQ's projected loss and how much it costs to run every year."

Mr Quirk said he was attending in his capacity as a small-time breeder and not in his role as Lord Mayor.

"I am not one to snipe at state government but what worries me is that without incentives we will lose jobs and no new ones will be created," he said.

The meeting also passed a motion of no confidence in Mr Hall.

AAP has sought a comment from Mr Hall.
