The interesting period of Australian Cricket 'keeping history IMO spans the career of Don Tallon. Many good judges reckon he was the best 'keeper in Australia in 1938 but just missed selection for teh England tour in favour of more seasoned campaigners BA Barnett and Charlie Walker for the first test tour of the post Oldfield era.
Both Walker and Barnett had indifferent tours sharing the 'keeping duties in the test (Jack Pollards book The Glovemen has photo of IIRC of Barnett missing a howler of a stumping chance - should have goon in teh books as a run out he was that far down teh crease

). As I said hindsight tells us that Tallon should have gone.
In the immediate post war period he was untouchable as our #1 keeper. he was a times simple brilliant (some say his leg side diving catch of Hutton off Lindwall at the Oval test when England were out for 52 is one of teh greatest in our 'keeping history) and his work in teh 46-47 home test saw him take a remarkable catch to dismiss Compton after it deflected off the 1st slip behind him. He was a lightning fast stumper but his briliance was matched by missed chances. I think he missed two catches in Englands 2nd innings at OldTrafford in 1948 (the only drawn test).
He missed the South African tour so Saggers kept and Langley went as his deputy. As Tallon aged and his deafness increased his was proned to mistakes but will still capacble of Brilliance he was overlooked in teh early 50s for Langley. Tallon ended up as Langleys deputy on the 1953 English tour.
Whilst Langley lacked the polish and skills of tallon he was very safe and more dependable hence his preference to the man some consider our best ever 'keeper.
