George Finch was born in New South Wales, Australia, but was educated in Paris and Zürich. He was a research chemist when he moved to Britain in 1912 and later served during the First World War with the Royal Army Ordnance Depot and the Royal Field Artillery. In 1915, at Portsmouth, Hampshire, George married Alicia Fisher, the daughter of a Kent barrister. However, George Finch was not Peter Finch's biological father. He learned only in his mid-40s that his biological father was Wentworth Edward Dallas "Jock" Campbell, an Indian Army officer, whose adultery with Finch's mother was the cause of George and Alicia's divorce, when Peter was two years old. Alicia Finch married Jock Campbell in 1922.
In 1934–35 he appeared in a number of productions for Doris Fitton at the Savoy Theatre, some with a young Sumner Locke Elliott. He also worked as a sideshow spruiker at the Sydney Royal Easter Show, in vaudeville with Joe Cody and as a foil to American comedian Bert le Blanc. At age 19 Finch toured Australia with George Sorlie's travelling troupe.
“Peter and the team offer professionally run, competitive golf at the best courses in the UK. It has been a great way for me to play the top venues under tournament pressure whilst meeting people I now class as friends. A tight ship is run too, with no questionable handicaps and scores, which are well within reason, picking up prizes is a refreshing change. Since my involvement from 2014, you can see the tour growing naturally year on year and given the schedule who can see it stopping. Every event is top class – and glad to be apart of it.”
