Disgraced greyhound racing trainers have spoken out about their treatment a year after they were caught up in the live-baiting investigation broadcast on the ABC's Four Corners program.

Legendary trainer Ron Ball, from Prenzlau, south-west of Brisbane, was one of 22 trainers warned off by Racing Queensland.

Police charged 37 people with animal cruelty.

Mr Ball admitted he was trialling his dogs at trainer Tom Noble's property at Churchable, south-west of Brisbane, in February 2015 where surveillance cameras recorded numerous incidents of live baiting, but he claimed he did not see it.

"I hadn't done anything wrong and I didn't see anything that was being done wrong," Mr Ball said.

He challenged Racing Queensland's determination against him, which also saw him removed from the industry's prestigious Greyhound Hall of Fame, and a decision was made earlier this month to reduce his life ban to 10 years.

But Mr Ball said he intended to take the matter to the Supreme Court to clear his name.

He was not charged with criminal offences.

"It's mentally, physically, financially been just destructive," he said.

"It's cost me approximately $140,000 now - no income for 12 months, barred from every greyhound track in Queensland and your character that you hold in the industry is being tarnished."

'I'm flat out paying my bills'

Glass House Mountains greyhound trainer and breeder Ray Gatti appealed his life ban through the Queensland Civil and Administration Tribunal where the term was reduced to 10 years.

The 91-year-old pensioner said the industry ban had a significant financial impact on him.

"I used to get a quid out of the dogs and I'm getting nothing out of them now and they're costing me. I've still got them," Mr Gatti said.

"I've got no money at all to tell you the truth - I'm flat out paying my bills."

Mr Gatti was also defending a charge of animal cruelty which related to him being on Noble's property where live animals were used as lure for the dogs.

Noble pleaded guilty in February to 15 charges of animal cruelty and was awaiting sentencing.

"I was clocking them [the dogs] and Tracey [Kunde] was grabbing them off the arm and putting them in the kennels," Mr Gatti said.

"If I'd have seen anything different on the arm I would've noticed it. But I never noticed any pig on the arm at all, only on a video afterwards.

"I had no idea I was there that day, until I got notification from Racing Queensland."

Live baiting a 'generational thing'

Racing Queensland stood behind its decisions and in a statement wrote: "Any determinations made by Racing Queensland to warn off for life were judged on the merits of each individual case".

Greyhound Racing New South Wales abandoned its investigations into eight suspended trainers in February because of concerns about the legality of the surveillance footage used to implicate the men.

RSPCA Queensland chief executive officer Mark Townend said officers nationally would continue to work with police to investigate and penalise offenders.

"I think we've got the easy pickings you might say and then it'll be a slow process trying to get underground to where it's still happening in the back blocks of Queensland," he said.

"I think it's [live baiting] a generational thing.

"I think some of those older people in the industry need to move out and realise we're serious about taking them to court and realise there's actually a serious animal cruelty charge and they could do some jail time."

Poor management 'to blame'

The president of the Australian Federation of Greyhound Breeders, Owners and Trainers Associations, Brenton Wilson, said while his organisation did not believe the practice was common, it backed the strong stance against animal cruelty.

"That's the only way our sport can move on is through zero tolerance and best practice and do things better than anybody else," he said.

Mr Wilson blamed poor management from the states' racing boards for the industry's current crisis, and said greyhounds - particularly in Queensland - needed better stadium facilities and safer tracks for the dogs.

"There hasn't been one policy, there hasn't been any positive thing for 20 years," he said.

Interim board to be announced

The Queensland Government appointed an integrity commissioner after an inquiry into the industry last year found Racing Queensland failed to do the job.

A spokesman said it would announce an interim board in the coming weeks after the last one was sacked.

But Animal Liberation president Chay Neal said he did not believe the inquiry's proposed changes would tackle all the welfare issues, particularly overbreeding and euthanising dogs that were either injured or not fast enough to compete.

"We certainly think it's had more than its chance and we see no alternative than for the industry to be shut down," he said.

Racing Queensland said it had increased adoptions through the Greyhound Adoption Program (GAP), and introduced rule changes designed to improve the health and welfare of breeding females and minimise the number of puppies born.
