Made a check and found this on the QANTAS website:-
Sir Wilmot Hudson Fysh KBE DFC (1895-1974)
Fysh flew the Longreach-Cloncurry section of Qantas' Charleville-Cloncurry air service and in 1922 piloted the first official airmail service in Queensland. He was appointed Manager in 1923.
He helped form Qantas Empire Airways in 1934 when the original QANTAS and Britain's Imperial Airways joined forces and later served as Managing Director and Chairman. He retired as Chairman in June 1966.
Hudson Fysh was knighted in June 1953 for his services to civil aviation. He died on 6 April 1974 aged 79, having lived through an era encompassing both the Wright Brothers' flight in the Kitty Hawk and the introduction of the Boeing 747 Jumbo Jet.
The website did not state that "McGinness left QANTAS, never to return...." or that when Paul McGinness died in Perth in 1952, his funeral was attended by only 2 persons.
