As much as I admire MacArthur's work, I must say he was still a megalomaniac, and his memoirs were very much one-sided. In the big picture, he definitely favored American forces much more than that of Australia. For example, he used almost exclusively (or entirely exclusively?) American forces during the Philippines invasion in late 1944, while the Australians were sent to invade Borneo in a campaign that did not really have significant strategic value at that stage of the Pacific War.

I don't believe he truely undervalued the contributions of the Australians, however. MacArthur knew he couldn't have done it in New Guinea without the Australian troops. MacArthur also actively courted John Curtin during the war, reflecting his belief that Australia played a vital role in the region.
