Some of the industry's most well-known trainers and owners including Reg Kay, Stuart Mills and Deborah Arnold, spoke on camera, saying live baiting was eliminated many years ago and the sport was 100 per cent clean.

Trainer John Thompson was captured instructing another man on how he should be smashing in a baby possum's head so the live-baiting of its mother could begin. It is "the most horrific cruelty you would ever come across" said Hayley Cotton, an investigator with Animal Liberation Queensland, who secretly filmed the abuse.

The airing of the footage on Monday night followed Fairfax Media's report on Sunday that a parliamentary inquiry has been set up to scrutinise allegations of industry mismanagement, inappropriate distribution of TAB funds and widespread mistreatment of dogs in the $50 million-a-year greyhound racing industry in NSW.

Evidence of widespread cheating and illegal live baiting throws into question the validity of thousands of greyhound races and millions of dollars, Four Corners reported. The program accused the sport's regulators of presenting an entirely different image of the sport; of glitz, glamour and animal welfare. A pig photographed during an RSPCA raid in Queensland.

Earlier this month, allegations of live baiting prompted simultaneous raids by the RSPCA and police in three states which resulted in 22 people being suspended.

Adam Wallish, chief executive of Greyhound Racing Victoria, released a statement on Monday night accusing the program of being unbalanced and saying it was a "small minority" involved in illegal practices. The Victorian government on Monday night announced a "broad investigation" by Chief Veterinary Officer of Victoria Charles Milne into allegations of animal cruelty in the greyhound racing industry. And Racing Integrity Commissioner Sal Perna will also conduct an investigation into "industry participants" with cooperation from Greyhound Racing Victoria.

The government will fund four additional greyhound welfare compliance and education officers and an extra full-time investigator in Greyhound Racing Victoria's investigations unit. Racing Minister Martin Pakula said the government would work with Greyhound Racing Victoria and animal welfare groups to stamp out live-baiting. "Live-baiting is barbaric, abhorrent and illegal – it has absolutely no place in Victoria's racing industry and it must be stopped," he said. The announcement follows the suspension of registration of the Tooradin Trial Track and 10 people allegedly involved in live-baiting. The Victorian government has committed $3 million to "beef up the inspectorate" of Greyhound Racing Victoria and their investigation capacity.

Mr Pakula said GRV had announced an end to the use of carcasses in training. He declined to say if he had faith in the integrity of GRV. "I don't think today is the day for me to be expressing full confidence in GRV," he said. "I've been pleased with the way they have responded." He said GRV had approached him about being able to carry inspections at any time of the day or night and without the authority of the property owner. "The government is taking advice about that as we speak," he said. The greyhound racing industry's annual awards night due to be held on Friday has been cancelled.
