The species is common in habitats such as tropical rainforests, eucalyptus woodland, open scrub, beaches, swamps, offshore islands.

On farms in much of Northern Australia, they are the most numerous bird species and are considered a pest by farmers, as they damage crops such as sweetcorn, peanuts, wheat and many kinds of fruit.

[14][15][16] The continued urban growth of Australia in the past decades has resulted in large areas of natural subtropical and eucalypt sclerophyll forest to be replaced by suburbs and parkland, especially in the regions surrounding major cities.

The density of the species in Brisbane has become such that the noise resulting from the congregation of large numbers of individuals in communal roosting sites located in urban areas, has become a source of complaints by local residents.

Increased development of land for agricultural activities is likely to be a significant factor influencing the rising population size of the species outside urban areas.

Since the species is reliant on a permanent source of water for their survival, large groups of Torresian crows are most commonly observed on cultivated land in the tropics and in the East of the country where annual rainfall is relatively higher.

[10] Whilst the distribution of Torresian crows has expanded further across all of Australia, the density of the species in arid areas remains low due to a lack of sustainable water sources.

[10] In the arid centre, the species is primarily confined to localised areas where the amount of water in streams and waterholes is enhanced by high runoff in surrounding regions.

[10] However, the development of irrigation systems and wells by the cattle and farming industry may have provided the species with sufficiently stable sources of water to allow them to establish in areas that were previously untenable.

Furthermore, food resources of the Torresian crow may be indirectly supplemented by the modification of land coverage, where native forests are replaced by lawns and parkland that are rich in invertebrates which also represent a significant part of the species' diet.

Finally, the large size of Torresian crows allows them to dominate food resources and hence experience little competition from other smaller urban bird species.

The urban sprawl in Australia is continually creating new habitat for the species and is likely to be a strong contributing factor in the observed increase in population size.

Even relatively small urban developments on previously untouched land can represent significant increases in breeding space for Torresian crows to colonize, given the large carrying capacity of these habitats.

[20] Between the months of January and August, large groups of crows congregate and roam nomadically across farmlands, forests and city suburbs.

The stick nest is built high in a tree, usually a eucalypt, however other locations such as power pylons and tall buildings are occasionally chosen.

Dogs, cats and humans are also occasionally swooped in nest defence, however not nearly as aggressively as notorious species such as Australian magpies and masked lapwings.
