Our Story

  • Peter and Una Rockliff together with their families have spent many decades perfecting their artisan tasting products.

    Peter was born to fish, and in 1949 the first commercial fishing boat he established was called the ‘Alva’, after his mother. Peter travelled eastward along the coast of Tasmania looking for fish where he met Una Barnett, who was from a well-known fishing family in Bridport.

    Peter & Una married soon after and joined their first names together to name one of their boats ‘Petuna’. Peter and Una continued to build upon their fishing interests and the next big milestone was the construction of Tasmania’s first deep sea fishing boat, the Petuna Endeavour in 1979. By 1990 the Rockliff’s had further broadened their fishing interests and expanded into Aquaculture.

    Peter and Una’s work pioneering Petuna Ocean Trout and Petuna Atlantic Salmon in aquaculture has been recognised with an Order of Australia Medal.

Proud Tasmanians Peter and Una have established their head office, factory processing and distribution facility in East Devonport, Tasmania. Located near the Spirit of Tasmania ferry terminal, Petuna can supply the rest of Australia quickly and efficiently.

Peter and Una still to this day live in the local Devonport area and are regularly on site at the Head Office for Petuna, to ensure that their premium seafood continues to shine and delight palates locally and internationally.



In 2010, Sealord Group Ltd, a global seafood enterprise and the leading seafood brand in Australia and New Zealand, bought 50% of Petuna. Today the business is jointly owned by the Rockliff family and Sealord Group, which brought with it a worldwide fishing, processing and marketing network.

The combination of a family business with a global enterprise has allowed for significant multi-million dollar investments, including a major upgrade at the Devonport factory and large investments in marine farm and hatchery infrastructure at Macquarie Harbour and Cressy. This is all while still being in touch with the needs and concerns of Tasmanian communities.
