Tiger quolls are generally nocturnal and rest during the day in dens. However, juveniles and females with young in the den can be seen during the day and may leave their dens when it is light out. Quoll dens take the form of burrows, caves, rock crevices, tree hollows, hollow logs, or under houses or sheds. Quolls move by walking and bounding gaits. Trails are not particularly important for quoll, although they forage and scent mark along runways and roads. Tiger quolls may live in home ranges that range from 580–875 ha for males and 90–188 for females. Most resident quolls are female, although one population study, both males and females were found to be split between transients and residents. Males have overlapping home ranges, but each has its own core area of at least 128 ha. The home ranges of females may overlap less. Quolls sometimes share dens during the breeding season. After copulation, females act aggressively towards males, especially when close to parturition. For the tiger quoll, olfactory and auditory signals are used more often than visual signals when communicating. Quolls greet each other with nose-to-nose sniffs, and males will sniff the backsides of females to check for estrus. Quolls also mark themselves with mouth and ear secretions. Some populations have communal latrines, while others do not. Rocky creek beds, cliff bases, and roads serve as locations for latrines.
