Many ways a dingo can be injured as well as escape from a trap. Soft Jaw traps are now required and they generally cant break a leg. Also the traps tend to catch a dingo just above the foot. There is baiting along roads in Grassy Creek, Boboyan, Naas Valley and on the Clear Range Firetrail. Also Yaouk Gap and the end of Orroral Valley. Baiting kills dingoes but (as you'd expect) it does not result in broken legs. I am not necessarily up to date with current practice on trapping but in the past it was carried out when targeting a specific animal which was usually only on private properties.
