Dual-Frontage Belongil Beach Hideaway Listed for $35m
With two waterfronts, bushland surrounds and a $35 million price tag, this Belongil Beach retreat could become Byron’s most expensive home ever.

A rare parcel of Byron Bay is primed to hit the market this week along the glamorous holiday spot’s priciest stretch of sand – Belongil Beach.
The designer digs belong to Leah and Kurt Rettenmaier, head of digital asset investment firm Revolution Tech. The couple have listed their Byron Bay hideaway, which sits on Childe St and has two waterfronts, for $35 million with Kim Jones of Jones & Co Real Estate.
The Rettenmaiers bought an original beach house on the 1776sq m block back in 2016 for $3.6 million, according to title records, and then reimagined the unique property into a sleek boho retreat worthy of its multimillion-dollar price tag.
The three-bedroom, two-bathroom compound at 4 Childe St sits at the end of the enviable strip, which is bordered on three sides by Belongil Beach, the Belongil Creek and uninterrupted bushland teeming with native flora and fauna.
In addition to the natural neighbours, the property is also surrounded by VIP residents in the exclusive peninsula, including Chemist Warehouse boss Damien Gance and Sasha Robertson.
If the Rettenmaiers and Jones achieve their $35 million goal, the newest listing could break the Byron price barrier of $33.5 million set by the Gance-Robertsons earlier this year.
Jones is also reportedly the agent behind the current Far North Coast record of $37 million. That deal was struck when Tom and Emma Lane of Oroton handbag fame bought their property, The Range, in nearby Coopers Shoot.
The primary two-bedroom residence is home to rendered white walls with integrated shelving and statement archways reminiscent of the uniquely smooth lines of the Greek Isles. The flowing curved interiors also reflect the calming contours of the coastal landscape on the home’s doorstep.
Designed for entertaining inside and out, the property features a spacious covered alfresco area with a built-in barbecue, manicured lawns, a bespoke fire pit and a private self-contained studio with an outdoor claw-foot bathtub.
Even kids – big or small – have room to play with a fun built-in skate ramp and an expansive beachfront lawn with sweeping views over the bay, Julian Rocks and the iconic Cape Byron Lighthouse.
The dream has space to thrive with architect-designed plans for a more contemporary beach house (STCA).
Perfectly positioned for surfing at coveted Belongil Beach, or kayaking and stand up paddle boarding along the creek, the home’s prized location is within 600m of Treehouse restaurant, is a six-minute walk to the heart of Byron Bay and approximately half an hour to the Ballina/Byron Gateway Airport, or less than an hour to the Gold Coast Airport.
The dual aspect home at 4 Childe St, Byron Bay, is listed with Kim Jones of Jones & Co with price expectations of about $35 million.

At the northern tip of Point Piper, hidden from the street and positioned directly on Sydney Harbour, “Radford” combines cinematic views, rare waterfront access and a fascinating connection to one of Australia’s most storied estates.
The five-bedroom residence occupies land once belonging to Paradis Sur Mer, the celebrated three-block waterfront estate that made Australian property history in 1982. The original mansion became the country’s first home reported to have sold for more than $5 million—and may also have inspired one of its fastest and most profitable resales.
Property developer and yachtsman Bernard Lewis purchased the estate at auction for $5.25 million, only to sell it within hours to English betting magnate and thoroughbred breeder Robert Sangster. Lewis reportedly made a $500,000 profit in the process.
Sangster renamed the property Toison D’Or—French for “Golden Fleece” and the name of one of his racehorses—and established it as a Sydney base with his then-wife, Susan. The estate subsequently changed hands and identities again, becoming Paradis Sur Mer, or “Paradise on the Sea”, during Susan’s marriage to financier Sir Frank Renouf.
After another headline-making sale near the peak of Sydney’s late-1980s property boom, the original mansion was eventually demolished and the waterfront holding subdivided. “Radford” now stands on one of those prized parcels, carrying a thread of that extraordinary history into the present day.
Harbour views take centre stage
Designed by award-winning architect Victor Berk and constructed in the early 1990s, the three-level modernist residence has been planned around its exceptional position.
Panoramic views stretch from the Sydney Harbour Bridge across Shark Island and Rose Bay to Manly. A prized northerly aspect fills the home with natural light, while bedrooms and living spaces open to decks, balconies and terraces overlooking the water.
The main living areas flow to a broad alfresco entertaining terrace, sunny swimming pool and level harbourfront lawn. Beyond the garden, a private jetty completes the quintessential Sydney waterfront lifestyle.
Inside, generous proportions make the home equally suited to private family life and large-scale entertaining. The formal dining area can accommodate up to 14 guests, while a Gaggenau-appointed kitchen incorporates an island, walk-in pantry and casual breakfast area opening to the poolside deck.
A fireplace anchors the principal living space, complemented by high ceilings, travertine floors and expansive glazing that keeps the harbour present throughout the home.
A private sanctuary on every level
The main bedroom is accompanied by two walk-in wardrobes, a sitting area and an ensuite featuring a spa bath, separate shower and twin basins. Three further bedrooms each have an ensuite, while a gym with its own kitchenette, built-in storage and bathroom can serve as a fifth bedroom or private guest retreat.
Additional spaces include a fitted home office, an upper-level family area, sauna, two powder rooms and a substantial laundry. A lift connects all three levels, and the central staircase sits beneath an atrium-style glass roof fitted with an electric retractable blind.
Ducted and zoned air-conditioning, extensive storage and a security alarm add everyday practicality. Internal access leads to an oversized secure double garage, with additional driveway parking.
Set in an elite cul-de-sac on one of Australia’s most prestigious waterfront streets, “Radford” is close to Lady Martins Beach, Prince Edward Yacht Club, the Royal Motor Yacht Club, Rose Bay’s marinas and leading schools. Double Bay’s restaurants, boutiques and village amenities are only minutes away.
It is an exceptional harbourfront residence in its own right—but its connection to the record-breaking Paradis Sur Mer estate gives it a place within the wider story of Sydney real estate.
