South Australia's latest tourism campaign will cement Adelaide and the state's position as Australia's wine tourism capital, the Minister for Tourism said this week.

Created by the South Australian Tourism Commission, the new Cellar Door campaign focuses on South Australia's famed wine industry and is part of the State's biggest ever domestic marketing push.

Tourism Minister Jane Lomax-Smith said that the campaign was aimed at high-yield, wine-loving east coast visitors.

"The campaign strongly promotes the fact that Adelaide has more than 200 cellar doors less than an hour's drive away" she said.

"[It] positions Adelaide and its surrounding wine regions as a cosmopolitan, beautiful and relaxed destination where visitors can reconnect with themselves and their partners in indulgent, authentic surroundings."

The Cellar Door campaign started last week with a successful online 'viral' campaign and continued this week with the launch of a new wine themed TV commercial. It is airing nationally with an emphasis on the Sydney and Melbourne markets.

Lomax-Smith added that the State's www.southaustralia.com tourism website now also features new wine and food information and holiday offers. A new South Australian Wine and Food Guide has also been launched as part of the campaign.
