Lesley Pope was the daughter of Captain and Mrs C.J. Pope. Her aunt was Nelle Grant Cooper. During Lesley's youth, Captain Pope was Captain-in-Charge at Garden Island, and the family were resident in Elizabeth Bay ('Said Good-bye', Sydney Morning Herald, 27 May 1936, p.7). Captain Pope then took up a position at Flinders Naval Base in Victoria. Through the late 1930s and at the beginning of the war, Lesley Pope as well as working on fund-raising with the Women's Naval Auxiliary. By 1942, however, she was become established as both a stage and a radio actress, including a role as one of the eponymous daughters in Digger Hale's Daughters.
In June 1946, Lesley Pope married Sidney Piddington, a former prisoner-of-war who had been held in Changi, where he had experimented with thought transference. The two became a mind-reading duo, performing together as early as 1947. In late 1948, the couple moved to England ('Piddingtons to Try Luck in England', Newcastle Sun, 9 December 1948, p.4), where they successfully (though not without some criticism) performed the act for some years.
The mind-reading act ended in London in 1952, and Sidney Piddington went to work in the publishing industry ('London Talk', Australian Women's Weekly, 4 March 1953, p.20).
The couple returned to Australia in 1954 ('Telepathy–All Past', Sydney Morning Herald, 1 April 1954, p.4 [women's section]).
