a kookabarra is a bird that is found in Australia
Australia's largest flying bird is the Australian pelican. With a wingspan that can exceed 3 metres, a height of up to 180cm and a weight of up to 13 kg, the Australian pelican is very clearly the largest flying bird in Australia. However, it is not unique to Australia, being found across the Pacific region known as Australasia. Beside Australia, it is found in Papua New Guinea and western Indonesia, and even in New Zealand and some western Pacific islands.Two other birds are more localised within Australia, and could be regarded as Australia's largest flying birds, though they cannot match the pelican in height, wingspan or weight.Australian bustard: it can grow up to 120cm in height, and its weight averages 450 grams. It is unique to northern Australia and the southern region of New Guinea.Jabiru, or Black-necked stork: its size is larger than the Australian bustard, growing up to a maximum of 133cm, but it is lighter, having an average weight of 410 grams. It is found only in Australia, so could conceivably be classed as Australia's largest endemic flying bird.
