In 1946 Waterson was runner-up in the
Australian Open at
Royal Sydney. After the first day he was tied for second place with
Ossie Pickworth, two behind
Kep Enderby, after rounds of 71 and 73. Enderby faded on the final day and Waterson's rounds of 73 and 74 were enough for second place, two strokes behind Pickworth, who had rounds of 69 and 76. The
Australian Amateur was also played at Royal Sydney, after the open. Waterson beat
Jim Pendergast in the final, to win the title. Waterson was 3 up after the morning round, but Pendergast levelled the match after seven holes of the afternoon round. Waterson again took a three-hole lead and, despite losing the 16th, won the match 2&1. Waterson won the
New South Wales Amateur Championship four times in five editions between 1939 and 1948, only losing in the 1946 semi-final to the eventual winner,
Kep Enderby. As a 17-year-old, he had reached the final in 1933, but lost to
Harry Hattersley. He won for the first time in 1939, beating
Jim Ferrier 4&3 in the final. He won again in 1940, 1947 and 1948. Waterson was twice runner-up in the
New South Wales Close Championship. At Killara in 1935 he tied with
Don Spence, the pair being 16 strokes behind the winner,
Jim Ferrier. In 1947 he finished two strokes behind
Norman Von Nida at Manly. He had also finished second, 6 strokes behind Von Nida, in the 1936
Queensland Open at Royal Queensland, and won the Queensland Amateur a few days later, beating
Mick Ryan 7&6 in the final. In 1948 Waterson represented Australia in the
Sloan Morpeth Trophy at
Royal Melbourne Golf Club, New Zealand winning 4½ to 1½. He lost his singles match to
Bryan Silk. ==Personal life==
