a breed of chicken raised for its meat and eggs, bred in Australia from Orpington stock in order to increase egg productivity and early maturity. Australorps are large fowl with wide, deep breasts and large, wide backs. The liveweight is 3.5–3.9 kg for roosters and 2.5–2.9 kg for hens. The annual yield is 150–180 eggs, and record yields of 250–300 eggs have been reported. The egg weighs 55–62 g and has a brown shell.

Australorps are bred primarily in Australia and the USA. The main breeding research in the USSR is being carried out at the Kurtna experimental station for chicken breeding at the Estonian National Experimental Institute for Animal Husbandry and Veterinary Science.
