Queensland racing stewards have laid a fresh charge against jockey Noel Callow after failing to attend a hearing over the emergence of another video of him allegedly racially abusing an Indigenous man.

The 50-year-old had already been disqualified recently for 10 months by Queensland stewards for a pair of videos shot in Darwin while appearing intoxicated during that city's 2024 Cup racing carnival over "racially charged language".

Callow's legal counsel launched an appeal over the severity of the two previous charges, but the penalty was upheld.

The Group 1-winning rider did plea guilty to both charges, but was left shocked over back-to-back five-month bans over filming videos away from the racetrack on the streets of Darwin's CBD that denigrated four Aboriginal people.

However, a third video appeared separately this month, apparently after stewards were tipped off, which alleges Callow racially abused a fifth Indigenous person during an exchange on another street.

Callow is not seen in the video, but allegedly it is the veteran jockey's voice that can be heard.

He was called to a new stewards' inquiry that was set to be held at the Eagle Farm racecourse in Brisbane.

After providing reasons to stewards as to why he could not front the hearing, the Brisbane resident was ordered to appear at the Queensland Racing Integrity Commission headquarters in nearby Albion.

Queensland chief steward Josh Adams said stewards attempted to contact Callow on a number of occasions in the lead-up to the rescheduled hearing, but he did not respond.

Adams said stewards decided to issue a new charge against Callow, under Australian Racing rule 232 (h), which states that a person must not "refuse or fail to attend or give evidence at an interview, investigation, inquiry, hearing or appeal when directed or requested to do so by the Principal Racing Authorities (PRA), the stewards or a person authorised by a PRA or the stewards".

No separate charge has been laid as yet over the stewards' recent investigation into finding a third video of Callow allegedly racially abusing the Indigenous man.

Callow's recent disqualification before his latest charge is the most serious of racing penalties.

A disqualification ban rather than that of a suspension from riding in race meetings also involves a jockey from attending racecourses, working trackwork for trainers, or using racing licenses of remaining involved in the industry entirely.

The punishment that began in August 2025 will last until at least June 2026, but the penalty may continue further depending on the outcome of the new probe.

Callow's defence during an appeal hearing in October to downgrade the penalty from 10 months was that the comments in his videos were "misplaced humour, not intentionally cruel".

He admitted that alcohol had affected his behaviour, but the "functioning alcoholic" said he didn't want to use his intoxication as an excuse.

Callow said since the incidents more than 12 months ago he has been remorseful, after engaging in a 90-minute course on First Nations culture and after talking with former Sydney Swans AFL star Michael O'Loughlin, a Kaurna and Ngarrindjeri man from the GO Foundation.

He told the Queensland Racing appeals panel that these experiences made Callow realise he had been "disrespectful" to Indigenous people.

The banned rider had told the hearing that he also allegedly received death threats after the Darwin videos were made public.

Callow said he has also undergone hypnosis therapy to put an end to his binge drinking.

But the winner of more than 1600 worldwide races across 35 years in the sport that includes five Group-1 wins in Australia from 2003 until 2006 is yet to issue a public apology.

Callow's lawyer Matthew Sterling told the appeals panel that the 10-month disqualification was "far beyond the established tariff for such behaviour where racing participants frequently have been suspended for four to six weeks".

But the appeals panel agreed with the ban handed down by the Racing Queensland.

"The applicant's comments were insulting and degrading, and they were definitely racist," the appeals panel wrote in its review of the earlier decision.

"Because of its very nature, this kind of behaviour should be condemned."

The panel recognised the impact of alcohol in Callow's behaviour had, singling out the offensive rant of his video on a bicycle.

"Alcohol was undoubtedly a contributing factor, especially regarding the second incident in chronological order. That might help explain the behaviour, but it doesn't make it okay."

The panel issued one final warning to Callow over his behaviour as his racing career appears to hang in the balance.

"Thoroughbred racing depends a lot on the trust of the public and people in the industry," they wrote.

"When racist or other offensive behaviour is caught on tape and shared widely, it can hurt that trust."
