Kollosche Cracks the Sale of a Decade
June 3 2025

A piece of Gold Coast history has turned a page with the landmark sale of ‘Bartinon’ at 26 Marseille Court in the waterfront enclave of Sorrento.
Sold by Kollosche’s trusted team of Sam Guo and Julia Kuo, the property achieved a record-breaking price of $18,000,000 setting a new benchmark for both Sorrento and the wider Bundall area.
Its sale is significant, given that the property has been on and off the market with various agents for more than a decade, without a successful sale.
However, a new chapter unfolded when Sam and Julia took on the listing. During the marketing campaign, they reached out to a contact in Kollosche’s shared database, who happened to reside across the river from the estate. While the new owner had long admired the property from afar, he had never considered it seriously until Sam invited him to a private viewing.
“It’s about educating the buyer and helping them see the long-term value,” Sam says.
“To finally match it with the right buyer after so many years of it being on and off the market is incredibly rewarding.”
Originally built for Sir Justin and Lady Hickey in the early 1980s, the Mediterranean-inspired mansion is well recognised. In its hey-day it hosted royalty, music, and Hollywood celebrities such as Frank Sinatra, Whitney Houston, and the Rolling Stones to name a few.
The new owners now plan to renovate Bartinon and make it their family home, bringing promise of a new future for the stately and historical residence.
The sale is also a signal of the strength of the Gold Coast property market and of what can be achieved with the right agent and strategy in place.
“Achieving $18 million is a testament to the strength of the Gold Coast’s prestige market and the power of a targeted, honest approach,” Sam says.
“We’re proud to set another record sale price for Sorrento and Bundall.”
Since April 2024, Team Sam and Julia have managed to secure the top three sales in Sorrento, with the latest superseding the previous record by more than $6,500,000
