On Harry Hawkers and Harry Kaupers return to work at Sopwith, they found three young Australians. Horri Miller, Bob Cousins and Bert Hinkler. They sat around the work shops listening to Harry's stories of his flights at Caufield Racecourse, Randwick, Albury and Ballarat. When war started Hinkler joined the Royal Naval Air Service and would have come across Harry Busteed and Sydney Pickles, by then both commanders of the RNAS.
