At 15 to 16 cm (6 in) in length, the eastern yellow robin is one of the larger Australasian robins, and one of the most easily observed. Pairs and small family parties establish a territory—sometimes year-round, sometimes for a season—and seem little disturbed by human presence. They appear not to migrate any great distance, but will make local movements with the seasons, particularly to higher and lower ground.

The eastern yellow robin occupies a wide range of habitats: heaths, melee, acacia scrub, woodlands and sclerophyll forests, but is most often found in damper places or near water. Like all Australian robins, the eastern yellow tends to inhabit fairly dark, shaded locations and is a perch and pounce hunter, typically from a tree trunk, wire, or low branch. Its diet includes a wide range of small creatures, mostly insects. Breeding takes place in the spring and, as with many Australian birds, is often communal. The nest is a neat cup made of fine plant material and spider web, usually placed in a fork, and expertly disguised with lichen, moss, bark, or leaves.
