Fred Nunn came from a prominent Ipswich family with a long association with soccer. His grandfather’s paddock in Dinmore was the home ground Dinmore FC club, one of the earliest clubs in the region, and later became the home ground for New Chum Bush Rats. That club was known as Dinmore Bush Rats by the time Nunn joined, following in the footsteps of several older relatives who played for the club. He was seen playing for Bush Rats lower division side in the early 1910s before progressing to the senior side by 1915. That year Nunn helped the club win the Charity Shield Final against St Helens.
Nunn worked as a miner for most of the war, but finally enlisted in May 1918. He left Australia in July, aged 25. Nunn arrived in London in September where he was assigned to the 15th Battalion. He did not arrive in France until in February 1919, well after armistice, where he was reassigned to the 14th Battalion. Nunn returned to England in May, the same month he married Euphemia Brown, who also came from a coal mining family.
The newlyweds left for Australia in 1920 where the Dinmore Patriotic Committee held a welcoming party. Nunn returned to mining, while the couple would have six children. In 1931 he was injured while working for the New Chum Colliery, which necessitated an operation. Despite the operation being thought of as a success, Nunn died suddenly in the following weeks at the age of 38. Euphemia lived in Ipswich until she passed away at the age of 89 in 1986.
