Bruce Vandersee says the "implications are unbelievable" for rural communities still recovering from the drought.

Looking at pictures on his office wall of a fleet of cotton pickers working on the property in its cotton-growing hey-day, he finds it difficult to accept that productive country has effectively been "locked up" for all time to the detriment of agriculture's future.

"My issue is that Federal Government money is being splashed around to stimulate the economy while here's a direct killer of the economy for questionable benefits," Mr Vandersee said.

"Minister [Penny] Wong's agenda appears to be she can fix the world with her climate change agenda and, while she's working on a theory, it's a fact she's killing off part of the Australian economy that's actually going pretty well."

Mr Vandersee speaks of the ripple effect flowing from the Twynam decision, principally the diminishing employment prospects for rural people, lost business to machinery companies like Vanderfields, and also the overseas implications.

This is a reference to a recent meeting with the giant US machinery company John Deere which now must get to grips with more shrinkage in Australia's cotton picker market.

"So the (buy-back) decision is even affecting a factory in the middle of the USA," Mr Vandersee said.

The managing director of Vanderfield, which was founded in 1963, and is one of this country's largest John Deere dealers, said the company first started doing business with Twynum in 1989 when it was Colly Farms and one of the Group's biggest customers.

"What I really want to push is that this decision not only will have some direct effect on our company but also the nation's economy - for all time," Mr Vandersee said.

"It's like carving off the Kimberley region of Australia and giving it to Indonesia – they've effectively locked it away, never to be used again."
