The nine properties encompass a total of 8662 hectares and will be run as a single 'hub'.

PrimeAg executive chairman, Peter Corish, said the total investment in these acquisitions was $47m, with a total of $223m invested to date in quality properties in the company's targeted investment regions.

"This investment aggregates 6580ha of dryland cropping and 1300ha of irrigated cropping lands with the balance being grazing and service areas," Mr Corish said.

"The properties are in two primary groupings with seven properties near Bongeen on the eastern Darling Downs and two properties located north of Dalby at Warra on the northern Darling Downs.

"The dominant crops will be grains, pulses and cotton."

Mr Corish said that establishing significant operations on the Darling Downs follows PrimeAg's strategy of diversifying its farming operations across 1200km of different geographic regions.

"We have a mix of carefully selected quality dryland and irrigated properties which will assist in mitigating the climatic risks often associated with agricultural production," he said.

PrimeAg's chief executive officer, John Stewart, said the Darling Downs holdings would be managed as a single hub and incorporate the Condamine property

of Lakeland Downs.

PrimeAg has now established regional hubs at Emerald, the Darling Downs, Goondiwindi, Moree and Gunnedah.

Through its property acquisition program, across its five hubs, PrimeAg now holds 39,750ha of land, which includes 10,500ha of irrigable land and 18,000ha of dryland cropping land.

"The development of our property portfolio has included the acquisition of water entitlements totalling 57,000 megalitres," Mr Stewart said.

"These entitlements are complemented by our on-farm water storage capacity of 37,000ML."
