He left school at the age of 14 to work on his family's orchard in Beelerup.
In 1942, Kitney enlisted in the Australian Imperial Force.
He served with the 35th and 42nd Battalions in the South-West Pacific, reaching the rank of lieutenant by the war's end.
He returned to his orchard after the war, and became prominent in fruit-growing circles.
Kitney entered parliament at the 1968 state election, unexpectedly defeating the sitting Liberal member in Blackwood, John Hearman, who was also the sitting Speaker of the Legislative Assembly.
However, he remained in parliament for only a single term before retiring.
The year after leaving parliament, Kitney moved to Lesmurdie, on the outskirts of Perth.
He worked as a fruit inspector with the Department of Agriculture for a period, and with his wife also ran a garden centre in Kalamunda.
