The Golden Bachelor Australia is filmed at the historic Tresco mansion located in Elizabeth Bay, Sydney. This grand heritage-listed waterfront mansion, built between 1867 and 1883, is known for its stunning sandstone facade, period features, and panoramic harbour views. The property includes multi-tiered lawns, a private gazebo, eight bedrooms, multiple formal rooms, and a private ocean pool, making it an ideal setting for the reality show's romantic and private moments. Tresco is considered one of Sydney’s most distinguished historic estates and serves as the backdrop for the show's first season in Australia in 2025.
