A Queensland jockey who was caught filming "racially charged" conversations mocking Indigenous people in Darwin last year plans to appeal against his horse racing suspension.

Noel Callow was slapped with a 10-month ban by Queensland racing stewards, preventing the veteran jockey from participating all forms of thoroughbred riding in Australia.

Callow had already pleaded guilty ahead of the hearing on two charges of "conduct detrimental to the interests of racing" over circulated videos of him ridiculing local Aboriginal residents while visiting Darwin's CBD for a race meeting in 2024.

The ruling which guides all sanctioned turf racing throughout Australia states a person "must not engage in a conduct prejudicial to the image, interests, integrity, or the welfare of racing, whether or not that conduct takes place within a racecourse or elsewhere".

Stewards whacked the licensed jockey with a five-month disqualification for each of the two charges.

The hefty penalty considered Callow initially circulated two derogatory videos via WhatsApp to racing associates, which only came to light publicly in July this year.

The 50-year-old's first suspension came after he, while appearing intoxicated, filmed a lone Aboriginal man on a busy Darwin street. Walking past while eating a pizza, Callow cynically offered the man a bite, but only in exchange for a shower.

Callow asked the man his name before beginning to mimic an Indigenous accent with what could only be described as racial, inaudible chatter, which extended to Callow calling the man "Yothu Yindi", before mimicking the band's popular song 'Treaty'.

In a separate incident he used a racist four-letter slur while erratically riding a bike on a footpath, holding a jockey whip and nearly crashing into three Aboriginal pedestrians.

Queensland racing stewards believed Callow's remarks were said in a manner which, in their judgement, was "clearly intended to ridicule" several Indigenous people.

However Callow's legal counsel argued for a four-to-six week ban was more appropriate, rather than the five months handed down for each of the charges.

Barrister Matthew Sterling did not dispute the remarks would be perceived as deliberately racist. He insisted the videos only came into the public domain after the footage was "leaked," saying Callow's remarks "were intended as misplaced humour, not deliberately cruel".

Mr Sterling also pointed to a precedent in other Australian sports of a much shorter suspension for racist slurs, adding there is "no reason racing should treat such matters more harshly than other sports".

However, in a Racing Queensland statement stewards vehemently disagreed, arguing the longtime jockey went out of his way to make the racist remarks public.

"The submission that a four-to-six week suspension, as typically applied in the AFL for racist or offensive remarks as an appropriate penalty overlooks a critical distinction," the report from the stewards said.

"In those cases, the remarks were made during play or in private settings, and not self-recorded, published, or circulated by the offending player".

Queensland chief steward Joshua Adams confirmed on Wednesday that Callow had lodged an appeal amid a Doomben racecourse meeting in Brisbane.

Another hearing will be held in front of a separate Queensland Racing appeals panel sometime within the next month.

The length of the disqualification, which is backdated to his last ride on July 29, could potentially strip Callow of hundreds of thousands of dollars of income over the course of 10 months.

Queensland racing stewards were unrepentant over the penalty or the loss of earnings.

"Racist and obscene language, even if intended as misplaced humour, as was submitted by Mr Callow, is objectively offensive, blameworthy and damaging to racing's reputation once it's been publicised," the report said.

"While Mr Callow contends that he only shared the footage with a limited number of associates, it remains the case that he created, recorded, and disseminated the material.

"That act initiated the chain of events, which foreseeably led to wider publication.

"A licensed person bears responsibility for the risks inherent in recording and sharing offensive material.

"The fact others may have contributed to its wider dissemination does not absolve Mr Callow of accountability for placing the content into circulation."

Callow had initially been stood down from riding – pending the outcome of the inquiry – with his licence suspended for three months.

The impact of the sanction had Callow unable to fulfil his rides at the Darwin Cup carnival, including the $200,000 Darwin Cup (2050m) on Bear Story, who finished last in the field.

Around the same time the racist videos were recorded, he rode the same horse to a third placing in last year's Darwin Cup.

Callow finished third on his last ride on Hills Minto over 1000 metres at Doomben.

The matter had been adjourned by stewards for several weeks to allow Callow to seek legal advice.

It is not the first time Callow has attracted the attention of stewards after allegedly instigating a physical altercation with a fellow Brisbane rider, Kyle Wilson-Taylor, inside the jockeys' room at a Queensland winter carnival race meeting which earned the former Victorian a three-month ban.

Pending appeal, Callow will not return to a track until the end of April 2026.
