Simplot's Birds Eye frozen vegetable packets will feature a prominent "Australian grown" logo from this month, with the photographs and stories of the people who produced them on the back of the pack.

A Newspoll survey conducted last month found that 90 per cent of Australians wanted to buy Australian-grown vegetables, Simplot managing director Terry O'Brien said at the company's Devonport plant.

"But that intention is not always translated into sales and one reason people give for that is confusion," Mr O'Brien said.

"This is us doing something to make it absolutely clear if you're buying Australian produce or not - if the logo is on the packet, it is 100 per cent Australian grown."

Almost all vegetables in Birds Eye's range are grown in Tasmania, vegetable grower spokesman Richard Bovill said, and the campaign was a welcome boost to an industry still recovering from news McCain was pulling out of Tasmania.

"In Tasmania, 97 per cent of people say they would rather buy Tasmanian-grown products, now that has been made easy to do," Mr Bovill said.

North-West farmer Matt Ryan, who features on the back of the cauliflower packages, said the true test was making sure mainland consumers bought the products.

"It's easy to sell Tasmanian produce to Tasmanians, that support has always been there, but we really need to make this a mainstream success in cities like Melbourne and Sydney," Mr Ryan said.

Mr O'Brien said Simplot was in a healthy position, despite being the last man standing in vegetable processing in Tasmania, and the success or failure of the campaign would not decide the company's future.

"This is not a survival move, this is an improvement move," he said.
