Sam Bonkowski × JT Allen
A stronger
connection.
Between your Highlands property
and potential buyers across Sydney’s wealthiest suburbs.
Local knowledge.
Established Eastern Suburbs relationships.

I’m proud to be joining JT Allen Real Estate, an established, family-owned, highly respected boutique real estate agency in the heart of Double Bay, as their licensed real estate representative for the Southern Highlands and Kangaroo Valley.

Double Bay NSW 2028
At home in the Highlands.
Connected in Double Bay.
The key advantage for my vendors is simple: I remain genuinely local to the Highlands, where I live with my family, while the office and the highly professional team are physically based in Double Bay, at the heart of one of Australia’s most prestigious property markets.
This goes beyond simply advertising your property to Sydney. It gives your property a genuine presence within the market where many high-value potential buyers live, work and spend their time, backed by an established agency with strong local relationships, buyer connections, deep market knowledge and an active database of high-net-worth individuals.
Why the Eastern Suburbs
connection matters.
JT Allen works within a prestige market where homeowners are buying, selling and considering their next move. Those conversations can open the door to a Highlands home, a country retreat or a Kangaroo Valley escape—sometimes before a buyer has begun searching for one.
Through my work with the Double Bay team, your property can become part of those discussions. That creates an opportunity to introduce it through a personal conversation and an established relationship, reaching potential buyers whose next move may not yet be reflected in a property portal search.
The connection brings together my local knowledge and relationships with the people, buyer connections and resources of the agency itself. I remain based in the Highlands, working directly with my Double Bay colleagues, so you have local representation supported by a team active in another important buyer market.
Why you need your property exposed in Double Bay:
Reporting on ATO figures for 2021–22, news.com.au identified Double Bay as “home to those with the highest average taxable income at $354,308 per year.”
Historical ATO figures for 2021–22.
For Highlands vendors, this helps explain the value of being represented within that market: the opportunity to introduce your property through established relationships with potential buyers who may have the means to recognise its full potential.


That physical presence is an important part of the advantage. JT Allen’s prominent New South Head Road office features a large-format, street-facing billboard-style LED display, providing the opportunity to showcase your property directly within one of Sydney’s most valuable property markets.
Sections of New South Head Road through Double Bay carry approximately 40,000 vehicle movements each day. The office is positioned at a key location on an important Eastern Suburbs corridor serving some of Sydney’s most prestigious residential postcodes, including Bellevue Hill, Point Piper, Rose Bay, Dover Heights, Watsons Bay and Vaucluse.
This means your property has the opportunity to be exposed and seen not only online, but physically within the environment where many of Australia’s highest-income households and potential buyers already are, as they travel, work, shop, dine and move through Double Bay as part of their everyday lives.
“The right buyer could make all the difference to your sale price.”
Combined with JT Allen’s vast high-quality buyer database, established Eastern Suburbs profile and relationships, direct buyer conversations, strategic digital marketing and prominent physical shopfront exposure, this creates a much deeper, far stronger, more direct and influential connection between a Highlands property and the Sydney market than advertising alone can provide.
Your property can be positioned within the very market where many high-value potential buyers already live, work and spend their time. Through JT Allen’s strong Eastern Suburbs presence and Double Bay location, your property gains deeper visibility in front of the audience most likely to recognise, appreciate and value your property’s full potential.
And that matters enormously, because the right buyer could make all the difference to your sale price.
