Kangaroo harvesting is not a commercial option for landholders,
resulting in greater animal rights issues for the kangaroos that are culled on private land.

In an article in Australasian Science, George Wilson argues that because animal rights campaigners are achieving their aim of reducing the demand for kangaroo products, there is an increase in animal suffering. Populations rise higher than the environment can support, and then crash. 

In recent years a lack of demand has meant that less than half the annual kangaroo quota for commercial use has been taken. Therefore, many graziers have sought other means to lower numbers of valueless kangaroos so that more income earning stock can be carried. Unregulated inhumane control mechanisms ensue.
