Ok Geoff, i just found a tree and it says that
Colin William Ross Dixon

Thomas Michael Dixon 1879-1954

Elizabeth Mary Schmidt 1884-1951
Siblings to Colin

Catherine Mary Beryl Dixon 1911-1994
Amy Coral Eileen Dixon 1913-1989
Big gap between Amy born in 1913 and Colin in 1922. I thought Thomas Michael might have been at war hence the gap in births but i cant find a military record for him.
