Formed in 1903 following a meeting at Royal Sydney Golf Club, the inaugural members of the NSW Ladies Golf Union were Royal Sydney, Marrickville (now Bonnie Doon), Lindfield (now Killara), Hunter's Hill (1900-32) and Dobroyde (1899-1920) golf clubs. By 1931, the NSW LGU was the largest golf union in Australasia with 174 clubs affiliated.
In September 1903, Miss Mabel Trevor Jones won the first NSW Ladies Amateur Open Championship. Three years later, Miss Nellie Meares of Mudgee triumphed in the inaugural Country Championship. Miss Pat Borthwick holds the record for most Amateur Championships with six wins (1948, 1949, 1951, 1952, 1953 and 1958).
Developing women’s golf was utmost to the LGU. The Junior Championship for Girls was established in 1929 with the first winner Joan Hood-Hammond (later known as Dame Joan Hammond, the operatic singer). The LGU assisted many including the Services’ Comforts Fund, Legacy, breast cancer services and individual golfers in hardship.
Renamed Women’s Golf New South Wales in 1998, it merged twelve years later with the New South Wales Golf Association to become Golf NSW.
