Australia, having been part of the British Empire had soldiers, if only a small amount, garrisoned in Singapore. When Singapore fell 85000 prisoners were taken, British and Australian. Australia were now underthreat as one of the reasons for Singapore to be taken was to get an advantage over Australia. Australia's main force was in Europe and Australia's main line of defense was destroyed. This lead to Australia looking to America as its "chief defender" of sorts, instead of its traditional defender, Great Britain. The loss of "The Gem of the British Navy" played a major part for the change in heart of Australia, the 'failure' of Britain. Where as America appeared to be regathering itself and had not lost the more important features of its Navy, unlike Britain.
