The dingo adjust's it hunting behaviour according to prey. Singularly they will take small mammals, reptiles, large insects etc. In pairs, they hunt wallabies, large reptiles etc. Remember the iconic Jean Paul Ferrero image of two dingo's tackling perentie in a South Australian salt lake. In packs, they tackle larger prey, cattle, horses, large macropods etc. Before they culled the 'more aggressive' packs on Fraser Island to sate our fear of everything, they frequently preyed on brumbies there. In locations around Australia, in area's where they hunt larger prey habitually, I have also found they tend to view lone humans on foot a little differently. Not suggesting they are the brumby solution, but they do prey on feral horses at times, amongst other species.
