Well my long held understanding and Wikipedia disagree.
"The small kangaroo farming community is a more environmentally friendly meat industry than sheep or cattle farming since kangaroos require no processed feed, are well-adapted to drought, and do not destroy the root systems of native grasses.
[3] However kangaroo farming is economically unattractive due to the start up costs and inability of the farmed product to compete financially against animals that have been killed by hunters under the government quota system.

Farm-free
Many people think kangaroos are farmed for their meat, but all the kangaroo meat on supermarket shelves and served up in restaurants comes from kangaroos harvested from wild populations.
Four species are commonly harvested – red kangaroos, eastern and western grey kangaroos, and the common wallaroo. Harvesting is regulated in each state by the relevant government authority, and management plans for the harvest must also be approved by the federal government.
According to the Department of Environment, the commercial kangaroo harvest is "one of the world's best practice wild harvest operations, with management goals based firmly on principles of sustainability"."
