Formerly the Commonwealth Trophy, it was presented by Nancy Viscountess Astor CH and the LGU. It originated when two Australian Ladies' Golf Union delegates (Miss Jean Derrin and Miss Mollie McLeish) suggested to the Ladies' Golf Union that a tournament should be conducted within the Commonwealth.
The idea was first accepted by the LGU, and later by three other countries – Canada, South Africa and New Zealand, when they were approached in 1957.
In 2007, the name of the event was changed to The Astor Trophy to allow players from Ireland to compete in a GB & Ireland team. The competition is held once every four years between teams from Australia, Canada, Great Britain & Ireland, New Zealand and South Africa. Each country is represented by 4 female players and each country contests foursomes and singles match play in a round robin format.
The Astor Trophy Tournament is quite unique in ladies’ amateur golf, with places in all five teams having traditionally being been much sought after as players vie to be recognised as one of their top four home talents, keen to pit their skills against highly competitive players from far afield.
The list of past players in the Tournament is, itself, testament to the attraction of the event. Past players also include, Lydia Ko, Melissa Reid, Minjee Lee, pioneering professional golfer Vivien Saunders, 2009 Ricoh Women’s British Open Champion and Solheim Cup Captain, Catriona Matthew, and respected golf commentator Maureen Madill.
