The concept of the Woomera in the early war years was great but concept and reality don't always match, its main role's was to be dive bombing, torpedo attack and ground attack , Vengeances and Dauntless's were soon replaced in the dive bomb role usually by P-40s as they could carry as much and look after themselves and the Beaufort as a torpedo bomber was not that successful, a/c the Woomera was to replace . Skip bombing as used at the Battle of the Bismarck Sea put the end to most torpedo attack and a/c like the A-20 , B-25 straffers and Beaufighters proved to be much better in the Pacific thearter.
Don't forget the japanese navy were the probably the most experianced at dodging torpedos in the world as they had trained against there own a/c and the japanese torpedos were faster and longer ranging than any allied torpedo, which also helped the skip bombers as the japs thought they were doing torpedo attacks and actualy turned there ships into the ideal positions for skip bombing.
I think CAC realised they were wasting there time continuing with the Woomera and started the move toward Mustang production in 1944
Great conceptual a/c with alot of advanced features ahead in some thing and dated in some even before production though a major achievment for the fledgling Australian aircraft industry.
