Although the main defence was provided by RAAF and Allied fighters, a number of Australian Army anti-aircraft batteries in northern Australia also defended against Japanese air raids.
A raid conducted by 54 land-based army bombers later the same day inflicted further damage on the town and RAAF Base Darwin and resulted in the destruction of 20 military aircraft.
[4] Japanese naval flying boats conducted four small air raids on the north Queensland city of Townsville and the town of Mossman in late July 1942.
The third raid on Townsville occurred in the early hours of 29 July when a single flying boat again attacked the city, dropping seven bombs into the sea and an eighth which fell on an agricultural research station at Oonoonba, damaging a coconut plantation.
The fourth raid on north Queensland occurred on the night of 31 July when a single flying boat dropped a bomb which exploded near a house outside of Mossman, injuring a child.
