Opps, I meant Australian War memorial website not war Museum.

It mentions some other interesting things too like the average height.

> {10} A recruit might conceal his age, but not his height. In 1939 the AIF minimum was 5 feet 6 inches (167.6 cm); a year later 5 feet (152 cm) was enough.[24] The patchy figures available suggest an average of about 5 feet 7.7 inches (172 cm), slightly shorter than the American average of 5ft 8.4in (173.7 cm).

And that recruits were dumb.

> 15} Australian army recruits were generally not highly educated: men assessed as requiring attention because they were 'educationally backward' were probably more common than those who had completed a full secondary course, and illiterates were two to three times more prevalent than the university educated.[37] The 1942-3 census found that approximately half the men in the Army had left school at age 14, two-thirds at or before that age.[38] Only 7 per cent had completed a full secondary course, and 1.4 per cent a degree or diploma.[39]
