A prominent dance teacher used her fingernail to hold cocaine under a teen's nose and told another girl to delete video of the drug-taking as it could "ruin her career".
The instructor's fears came true as the cocaine-snorting video taken late at night in the toilet stall of a Gold Coast pub instead found its way to police.
Sonja Yvonne Middelbosch, 53, faced Brisbane Supreme Court on Wednesday for sentencing after pleading guilty to two counts of aggravated supply of cocaine to a child aged 16 or over.
She also pleaded guilty to three counts of supplying dangerous drugs before receiving a suspended jail sentence.
Middelbosch trained in London and spent 25 years flying regularly to Sydney to train some of Australia's leading dancers.
She was now barred from several dance schools and had put her house on the market due to financial difficulties, Justice Sean Cooper heard.
Middelbosch twice supplied cocaine to a 17-year-old girl while out with the victim and her friend on May 17 and into the morning of May 18, 2024, crown prosecutor Caleb Theunissen said.
"The defendant repeatedly offered (the victim) and others the dangerous drug cocaine," he said.
At 1am, the dance teacher and one of the teens went to a bathroom and there the woman took cocaine out of her purse while the friend filmed over the toilet cubicle.
Middelbosch could be seen in the video dipping her finger in a clip-seal bag and discussing the effects of cocaine, the court heard.
She told the teen to tilt her head back and she put her nail under the girl's nose to allow her to sniff the cocaine.
Middelbosch told the victim's friend to delete the video as it could "ruin her career and she could lose her green card", Mr Theunissen said.
The victim was again offered cocaine when their car broke down after leaving the pub.
Middelbosch put some of the cocaine on her finger and told the teen to push her top lip up, using her finger to rub the drug into the girl's gums.
That the dance teacher would twice ask for the toilet video to be deleted showed that she was fully aware of the seriousness and potential consequences of her actions, Mr Theunissen said.
"It was a severe breach of trust ... the victim has a sense of betrayal," he said.
But Middelbosch should be spared time in custody as she had no prior criminal record and had lost the career she had wholly dedicated herself to, the court was told.
"She has been publicly shamed ... her whole life has changed as a result," defence barrister Anthony Kimmins said.
Justice Cooper said he was concerned Middelbosch had not expressed remorse but her punishment from outside the court was a significant factor in sentencing.
"You are not a regular user of cocaine ... you possess no other qualifications. You have been unemployed for some time now," he said.
Middelbosch was sentenced to six months' imprisonment that was wholly suspended.
She declined to comment as she left court.
