In 1936, there was a further controversy when the Australian national eight, preparing for the Berlin Olympics, was excluded from the Grand Challenge Cup because the crew was composed of policemen, deemed to be 'manual workers'. The resulting embarrassment persuaded the Amateur Rowing Association and the Stewards of Henley Royal Regatta of the need for change. On 9 June 1937, the offending references to manual labourers, mechanics, artisans and menial duties were deleted from the ARA rules; Henley's rules were changed the following day, coming into effect from the 1938 regatta.
