My parents Nina and Steve are both Greek immigrants to Australia and met each other while picking grapes in the Riverland in 1961. They soon bought a plot of land on which to build a farming business and in 1965 they proudly picked the first grapes off their own vineyard.

I grew up amongst these vines, learning the family business before founding the winery next to our vineyard in 1985. Our winemaking style quickly struck a chord as we began exporting our wines around the world, finding particular early success in the UK and Canada.

From these beginnings we have grown to become one of Australia’s most significant grape growers and wine exporters, strongly focused on long term relationships with customers around the world and building our reputation for quality, reliability and continuous improvement.

Sadly, both Nina and Steve have since passed away. I continue to run the winery and vineyards, while my wife Ivanka looks after key export customers. Our three daughters manage the ‘Mo Sisters Vineyard’ and contribute to our business development teams.

Meet our people

Bill Moularadellis

Managing Director

After graduating from Roseworthy with a winemaking degree in 1985, Bill was intent on setting up his own winery, which he did on his parent's Riverland vineyard property that same year.

Bill's winemaking skills and business acumen ensured the winery enjoyed steady growth throughout the 1980s and then when Australian wine began to grow in popularity overseas, Kingston Estate was well placed to help satisfy this new demand, with Bill jumping on a plane numerous times a year to visit key export markets.

He continues to run the winery as Managing Director and oversees winemaking as Chief Winemaker.

Bill is a past executive committee member of the South Australian Wine Industry Association, past Chairman and board member of the Riverland Wine Industry Development Council, past member of the Business Advisory Board to the Reserve Bank of Australia as well as a past non-executive board member of Wine Australia.

Nina (1940-2019) & Steve (1930-2023) Moularadellis

Nina (short for Constantina) and Steve (Australian for Sarantos) both emigrated from Greece to Australia as young adults, seeking a better life in the 'lucky country.' They met while picking fruit in the Riverland region of South Australia, where they had both chosen to settle.

When they could afford it, they bought their own block of land on which they gradually planted fruit orchards as well as a vineyard.

Sadly Nina passed away in 2019, she is fondly remembered by the Kingston family.
