[1] It was the professional equivalent of the amateur Australian Men's Interstate Teams Matches, which had been held since 1904.
[2] In 1931 at The Australian Golf Club the shield was played as a stroke-play event with teams of five, all five scores counting.
South Australia won with a score of 373, 10 ahead of the combined Queensland and Tasmania team.
Queensland entered as a separate team for the first time and beat Victoria before losing 3–2 to New South Wales in the final.
Billy Bolger won both of his matches after extra holes, with Bill Holder also twice on the day.
New South Wales met Victoria in the final and, although Norman Von Nida and Eric Cremin won the top two matches for New South Wales, Victoria won the last three to win the shield for the first time since 1932.
[11] The organisation of Australian golf was changed after World War II with the open and amateur championships being separated, although they were often played in the same city at about the same time.
Cremin reversed the result of the previous year against Pickworth, Martin Smith being the only Victorian winner.
New South Wales won 3–2 with Jim Moran beating Martin Smith at the 19th hole.
[17] The 1952 event at Lake Karrinyup saw the top three Victorians, Peter Thomson, Pickworth and Jack Harris, all winning their matches.
Ossie Pickworth beat Norman Von Nida but Kel Nagle, Eric Cremin and Jim McInnes won their matches.
Victoria had a narrow win over Queensland in the semi-final and met New South Wales in the final.
Pickworth again beat Von Nida but wins by Nagle, Cremin and Len Woodward ensured that New South Wales retained the shield.
Les Wilson and Len Boorer were still level after 20 holes but abandoned their match with the result decided.
[22] In 1957 the shield was contested as a north versus south match at Kingston Heath Golf Club.
