Pacific Black Ducks form pairs for the breeding season.

The adults breed in winter to spring in the south, summer to autumn in the north and when the rivers are flooding in the inland. The male preens, bobs and flaps his wings to attract a female. The adults mate.

The female lays seven to thirteen eggs in a scrape on the ground, a cup-shaped nest in reeds or a hole in a tree. She sits on the eggs to keep them warm.

The chicks hatch after three and a half to four and a half weeks.

The chicks grow into adults.
