David and Wizz O'Dea are the founders of Windowrie Estate. David O'Dea completed a degree in Agriculture at Hawkesbury University in 1961. Wizz O'Dea began her life on a farm situated near the Hunter Valley and married David in 1964. Windowrie was purchased in 1959 and David and Wizz worked together in the production of various cereal crops.
The decision to diversify into grape growing in the 1980's dramatically changed the family's fortunes. From humble beginnings Windowrie Estate now boasts the region's first winery and employs up to 45 people in casual labour and 14 people in full time labour.
