In general, the pied currawong is sedentary, although some populations from higher altitudes move to areas of lower elevation in winter. However, evidence for the extent of migration is conflicting, and the species' movements have been little studied to date. More recently still, a survey of the population of pied currawongs in southeastern Queensland between 1980 and 2000 had found the species had become more numerous there, including suburban Brisbane. One 1992 survey reported the total number of pied currawongs in Australia had doubled from three million birds in the 1960s to six million in the early 1990s.
