Gunns' business is continually expanding. The development of our 200,000 hectare plantation estate over the pastÂ twenty fiveÂ years represents a major achievement for us and will ensure a sustainable, forest products business into the future. In 2007, Gunns acquired the Auspine business which has significantly increased Gunns' plantation resource base and provides growth opportunities for the groups' forestry and manufacturing activities.
