Caretakers of a heritage-listed Queensland landmark are calling for outback tourism funding as the site faces closure for the second time. 

Tour guide Bob Willow says closing the country’s last remaining wool scour in the central-Western town of Blackall would be a tragedy for outback tourism. 

Mr Willow says the wool scour was promised at least $18 000, but a lack of funding has resulted in low visitation. 

“They said they would pay our big expenses like maintaining our steam engine and our diesel supplies,” Mr Willow said.
