The Estate
A Hidden Gem Worth Discovering
Cornwallis House is a hidden sanctuary nestled among the orange groves on the banks of the Hawkesbury River. Architect-designed in the classic Queenslander tradition, the property offers something the wedding industry rarely delivers: complete and absolute privacy. No staff wandering through your evening. No neighbouring weddings. No shared spaces. Just your people, your story, and one of the most beautiful river settings in New South Wales.

“Choosing Cornwallis House was the best decision we made. The sunset over the Hawkesbury provided a backdrop that no stylist could ever replicate. Alannah and Angelo made us feel like the property had been built just for us — it felt like our own private world for 48 hours.”
