The son of an Australian doctor who took his medical degree at Oxford University and then settled at East Grinstead, Sussex, Frazer was educated at Winchester College where he was an all-round sportsman.
[4] Frazer did not play for Oxford that summer or the next, instead turning out for Sussex, for whom he was qualified by residence, in a couple of County Championship matches in 1921, and a further five games in 1922.
[7][8] In September 1923, before starting his postgraduate year, Frazer was a member of a Free Foresters side that toured Canada, playing seven two-day matches.
He played in most of the team matches in the 1924 season, batting mainly in the middle order, but his best score and his only total ever of more than 50 was made as an opening batsman, with 81 in the match against H. D. G. Leveson-Gower's XI at Eastbourne, a rather weak team composed entirely of amateurs, many of them not in the first flush of youth (Ernest Smith, the captain, was 54 and had played for Oxford University 36 years earlier in 1888).
According to his obituary in The Times, Frazer was awarded a first-class degree in 1924 and then stayed for a further year at Oxford to act as a chemistry "demonstrator" at Balliol.
