A number of coffee vans across South-East Queensland are helping veterans and first-responders manage post-traumatic stress disorder (PTSD).

Terry McNally, an ex-Navy personnel, founded 3 Elements Coffee to help ex-service people adjust back into everyday life by providing them their own coffee vans, equipment and beans to set up their own business.

The coffee vans, mostly run by ex-Defence personnel or families, give a portion of their sales to the charity PTSD Resurrected.
