AIF is defined as:
The Australian Imperial Force (AIF) was the name given to two all-volunteer Australian Army forces dispatched to fight overseas during World War I and World War II. It doesn't say men or women.
BUT..

AIF Women's Association (1940 - 1946)
The AIF Women's Association was established in 1940, by the wives of six service officers. The main purpose was to bring together, in fellowship and understanding, the womenfolk of the men on active service so that they could help each other in time of need. The Melbourne City Council provided rent-free premises at 437, and later 435A, Collins Street Melbourne. Here the women could seek assistance or advice, have a cup of tea or leave a child while attending the doctor, dentist or an urgent appointment
so... both could be right.
Another stupid blunder by the board of studies
