A glamorous Melbourne socialite has appeared before a Victorian court over allegations she spiked a fellow guest’s vodka during a ski resort birthday party. The Mt Buller drink spiking case has sent shockwaves through the city’s elite social circles and is now very much a matter for the courts.

Amy Tossoun, 33, was charged over the alleged amphetamine spiking last July at a party in Mount Buller, a ski resort village in Victoria’s east popular among society circles. She faced Mansfield Magistrates’ Court on June 10.

What Allegedly Happened at Hotel Pension Grimus

Paramedics were urgently called to the award-winning Hotel Pension Grimus in the early hours of July 27 last year after the alleged victim, Melissa Jreissati, 33, reportedly suffered heart problems and was left clammy with cold sweats.

The alleged incident happened at 11:49pm on July 26, 2025, at the ski slope resort- a favourite winter playground for Melbourne’s rich and glamorous.

Police allege Tossoun, co-founder of The Richmond Dentist with her ex-husband Dr Fady Tossoun, spiked Jreissati’s drink with drugs during a gathering for a mutual friend’s birthday. Police allegedly found Tossoun in possession of amphetamines two days after the incident.

Victoria Police confirmed the incident took place at a licensed premises on Mt Buller, describing charges against a 33-year-old Brighton woman without naming either party directly.

Who Are the Women at the Centre of This Case?

Melissa Jreissati is the marketing director of prestigious family-owned winery Levantine Hill Estate and the daughter of Dr Elias Jreissati, chairman of the Jreissati Group one of Melbourne’s leading property development companies. The wealthy family recently relisted a sub-penthouse in Melbourne’s iconic Eureka Tower for just under $13 million. Jreissati is described as a regular fixture at society events, though she tends to keep a restrained presence on social media. She has since deactivated her accounts.

Tossoun, on the other hand, has long been a familiar face in Melbourne’s VIP scene. A mother of three who moves in glamorous circles, she has attended invitation-only events including the Glamour on the Grid party at the Australian Grand Prix and the Melbourne Cup Carnival, and has featured in publications including Vogue Australia. She was tipped as a potential new star for the reboot of The Real Housewives of Melbourne. She has since deactivated her own social media accounts. Tossoun’s estranged brother, Tony Farag, was separately charged in March with stealing event passes for the recent Australian Grand Prix. He is due to face Melbourne Magistrates’ Court in September.

The Charges and What They Could Mean

Tossoun faces two charges: possession of amphetamines and introducing a drug of dependence into another person’s body. Both offences carry penalties including fines of approximately $6,000 or up to one year in prison.

A spokesperson for Tossoun addressed the charges publicly. “Ms Tossoun is taking this matter extremely seriously and has retained lawyers to represent her interests,” the spokesperson told the Herald Sun, adding that since the matter is now before the court, she would not be making any further comment.

The relationship between the two women has not yet been publicly confirmed, though both allegedly attended the same birthday gathering at the mountain resort that night.

Wealth, Glamour, and a Night Gone Very Wrong

Mt Buller has long served as a winter retreat for Melbourne’s moneyed set. The exclusive ski resort scene is legendary among the city’s well-heeled, with lavish house parties a regular fixture. One favoured gathering spot has been the penthouse in the Timbuktu complex once owned by media mogul Antony Catalano currently on the market for around $9.25 million.

What began as a birthday celebration among friends last July has ended with court appearances, deactivated social media accounts, and a very public legal process. The case continues to be closely watched by those who move in the same and by plenty of people who don’t.

According to Victoria Police’s information on drug offences, introducing a drug into another person’s body without their knowledge is treated as a serious criminal matter under Victorian law.
