A PRICE guide of $45 million is anticipated for two significant cropping opportunities in Western Australia’s Great Southern region.
Offered via separate expressions-of-interest campaigns, the Wimburra Aggregation and Possum Hill comprise five properties across 7398ha.
James Auty and Glen Phelps from Nutrien Harcourts have been appointed to handle the sale of both properties.
Mr Auty said the Wimburra Aggregation and Possum Hill represent an opportunity to secure significant scale in one of WA’s highly regarded grain-growing regions.
“Large-scale cropping opportunities of this nature are becoming increasingly difficult to find and assemble, particularly within established and tightly held farming districts such as the Great Southern.”
Mr Auty said the properties offer immediate scale, proven productivity and significant production capability.
“Opportunities boasting more than 7000ha typically generate strong interest from local operators, family farming enterprises and larger-scale agricultural investors seeking expansion, additional scale or a standalone cropping operation.”
Mr Phelps said the assets combine strong farming fundamentals with proven production capability.
“What makes these opportunities particularly compelling is the strength of the farming country and their proven production history,” Mr Phelps said.
“The properties are well located and feature productive soil types, reliable rainfall, established infrastructure and proven broadacre cropping capability.”
Stage One of the EOI campaign for the Wimburra Aggregation and Possum Hill closes August 27.
