However, the Racing Appeals and Disciplinary Board suspended $A4000 of the fine, which Londregan will not have to pay provided he does not commit a similar offence again within the next year.
Londregan, 54, had originally pleaded not guilty to a charge of making comments prejudicial to the image of racing.
However, he changed his plea to guilty at the hearing, which made him eligible for a discount on penalty.
Londregan made the comments at the centre of the charge after Racing Victoria suspended jumps racing in the state pending a review of the sport following deaths at a Warrnambool meeting.
Londregan was quoted in what Racing Victoria described as numerous media outlets, saying that he would video his horses being shot, have their heads cut off and sent to the Minister for Racing, Racing Victoria Ltd and an animal group opposed to jumps racing.
Racing Victoria official interviewed Londregan over the remarks and charged him.
Londregan has been been involved in racing for more than 40 years, as a jockey and, for the last few years as a trainer.
Racing Victoria reinstated jumps racing 11 days after the suspension, with several immediate changes and the promise of a review at the end of the jumps season.
