With a licence to feed 10,000 head, the Wallumba feedlot grain finish the majority of MDH's cattle. After being purchased in 2001, Wallumba has changed MDH from a grass finishing to a backgrounding operation, with 90 percent of MDH's cattle being grain finished in the feedlot. Wallumba, in addition to Nangram has provided significant 'drought proofing' capabilities to the MDH operation insuring cattle can be finished even when the northern properties experience a dry season. 

Employment opportunities include feedmill manager, operator and feedmill hands, livestock manager, stock men and women and administration manager. Wallumba has a range of accommodation facilities available on site to cater for families and single workers.
