A trial of 28 provenances of Acacia auriculiformis was assessed for survival and growth at the age of 12 month. Of these provenances 7 where from the Queensland and 15 from Northern Territory, Australia and 6 P New Guinea. All provenances survived very well (> 92%), but they differed very significantly (p < 0.001) in their growth performance. A selection of provenances from Northern Territory and Queensland were among the top performers, with East Alligator River (16152) being the best. The results indicate the presence of genetic diversity in this species and support the need for genetic improvement.
