RHOS Sydney star Nicole O’Neil and her husband Adam have purchased a grand Bellevue Hill estate for $17 million. Less than a year after The Real Housewives of Sydney star told Home Beautiful it would take a “real-estate unicorn” to convince her to permanently leave her spectacular Vaucluse residence, Nicole and husband Adam O’Neil have found exactly that.
A Historic Bellevue Hill Estate
The five-bedroom, three-bathroom property sits privately on approximately 1346 square metres in Sydney’s prestigious eastern suburbs. Built in 1925, the stately home was extensively renovated in 1939, when a second storey was added. The sprawling grounds offer established gardens and terraced areas that enjoy views stretching across the harbour from Rose Bay towards Mosman and Manly.
Four of the bedrooms are positioned upstairs, including the main king suite, while a fifth bedroom with its own ensuite sits on the lower level. The interior features original-style fireplaces, high ceilings, and traditional windows. A light-filled dining space opens towards the harbour, connected by a sculptural curved staircase. The property was marketed by Michael Pallier and Di Wilkenfeld of Sydney Sotheby’s International Realty. While Nicole’s former home adopted polished, personality-packed interiors, the Bellevue Hill property offers something quite different: an established grand residence with almost a century of history behind it.

And despite its eight-figure price tag, Nicole already has a few changes in mind. “For now, we plan on new carpets and a fresh coat of paint,” she told The Sydney Morning Herald, adding: “The energy of the home is magnificent.”
Entertaining on a Grand Scale
Anyone familiar with Nicole’s interiors knows that entertaining is never an afterthought. When Home Beautiful toured Nicole and Adam’s previous Vaucluse home, she told us she could just as easily cook for 24 people as two. The family had hosted everything from a 150-person sit-down dinner in a marquee to a children’s foam party. They even installed a sushi train on their enormous kitchen island for one celebration.
Her background as a professional event planner was evident throughout the property, which balanced formal rooms with spaces designed to actually be lived in. Nicole O’Neil’s new home appears to offer just as much scope for entertaining, albeit on an even grander scale.

The expansive garden is particularly enticing, with broad lawns and established landscaping creating the kind of setting made for long lunches, parties and family gatherings. Tucked behind high walls and established greenery, this private courtyard has the feel of a secluded Sydney resort.

The ‘real-estate unicorn’ Nicole was waiting for
The purchase is especially interesting given what Nicole told Home Beautiful when we toured her former residence in 2025. At the time, Nicole and Adam had considered selling but she admitted finding something worthy of replacing their much-loved house wouldn’t be easy. “What we have is very hard to replicate, so it would have to be a very special property to replace this,”
