Winbourne was granted to George Cox in the early 1800s who built Winbourne and established a large estate, which included orchards, vineyards, wheat fields and dairying. The family remained on the property until 1901. In 1914 Tom Campbell leased the property and ran it as a holiday resort until 1958 when the site was purchased by the Christian Brothers. The main house was destroyed by fire in August 1920.
