WINE Industry Development Minister Margaret Keech has told a parliamentary estimates hearing Queensland's wine industry is a bankable investment, but needs finance sector support to achieve long-term growth and prosperity.

She has said the same to a group of financiers at a function at Sirromet Winery last month, held to demonstrate the industry's potential.

Participants were later taken on a 'familiarisation' tour of Witches Falls and Cedar Creek wineries on Mount Tamborine. Witches Falls focuses on contract winemaking with less emphasis on wine tourism. Cedar Creek is a diverse wine tourism-focused outlet with multiple income streams such as a restaurant, glow-worm tours, a cellar door and spring water.

"The familiarisation visit was important to confirm the opportunities for investment that was discussed at the earlier briefing and to also allow them to sample local wines. All were very impressed," says Ms Keech. Ms Keech said advancing the Queensland wine industry was closely linked to development of the state's food and wine tourism industries, a major growth factor for many smaller wine producers.
