Calf roping is effectively banned in two states, Victoria and South Australia, through a mandated minimum body weight of 200 kg for cattle used in rodeos. In other states, calves as light as 100 kg can be used for roping and there are no laws prohibiting the use of unweaned or recently weaned calves. A recently published paper highlights the inconsistencies in regulation of calf roping between Australian jurisdictions [7]. The authors concluded that calf roping causes unnecessary harm which raises concerns regarding the adequacy of legal protection for calves in jurisdictions where calf roping is permitted. There are ongoing efforts by the RSPCA and other advocacy groups to change the legislation so that all jurisdictions mandate a minimum body weight of 200 kg for cattle used in rodeos or alternatively prohibit the event.
