Country and folk musicians including Slim Dusty, Stan Coster, Rolf Harris, The Bushwackers, John Williamson, Graeme Connors and John Schumann of the band Redgum, still record the old bush ballads. Contemporary artists including Sara Storer and Lee Kernaghan draw heavily on this heritage. Ashley Cook, a contemporary balladeer, sings about topics relevant to life in agriculture and mining work in Australia's outback: "Cattle, Dust and Leather" and "Blue Queensland Dogs". His song "Road to Kakadu" is about killing water buffalo in Northern Territory in the 1990s to control the Brucellosis disease. "Beneath the Queensland Moon" covers the life and death as a drover.
