A former flight attendant had sex with a 15-year-old schoolboy but spends just a week behind bars.

Before securing a job as a stewardess with Tiger Air, Melissa Nosti, 33, worked as an attendance officer at a school in northern Sydney, Australia.

Of course, as an attractive woman and surrounded by hormonal teenagers, she easily captured one student's interest.

Instead of discouraging the student, she took full advantage of her influence and invited the young teen to have sex with her. She was 23 years old at the time.

A few years after leaving her job at the school, Melissa's secret fling with the teen came to light.

Soon after her arrest, she was sentenced to 18 months in jail with a six-month non-parole period after pleading guilty to sexual assault.

However, after spending only 8 days in jail, her lawyer successfully lodged a bail appeal.

Her lawyer told the court that Melissa was at 'low risk' of engaging in similar behavior again based on a doctor's assessment.

The lawyer said:

"She has had an employment history after this. She was in the airline industry."

And Judge Susan Horan said the victim impact statement from Melissa's victim was 'compelling' before granting her bail.

The court later released her as she awaits an appeal hearing.

Despite the release, Melissa has to abide by several conditions while she's in the community.

The bail conditions include having one mobile phone and giving the police her password when they ask.

She is also not to contact the victim, nor any other person under the age of 16.

Lastly, she must remain at her residential address in Ryde, and she's not to move or stay overnight anywhere else.

Following her release, Melissa reported to the police station for the first time. She dressed down in black tracksuit pants and an off-white Nike T-shirt.

She paired a loose-fit off-white crew neck with a denim jacket as she arrived at Eastwood Police Station.

Also, she looked comfortable in sneakers and Homer Simpson socks for the appointment.

The 33-year-old also threw her hair into a loose, low bun at the nape of her neck.

The casual get-up was a far cry from photos she had previously shared, showing her dolled up in her uniform as a flight attendant. In other pictures, she posed in bikinis on the beach.

Spending about an hour inside the police station along with an older man, Melissa came out 'rather distraught,' according to onlookers.

Melissa's case has sparked controversy on social media.

Many point out that if Melissa was a man and her victim was a female student, the sentence would have been harsher.
