I’m doing a bit of research for an article and I came up with the finding that the NSW Liberals have had twelve leaders since 1975 when the unlamented Robin Askin left office . Only Nick Greiner (1983-92) has lasted more than three years, and quite a few never even faced an election.

In the same period, Labor has had only three leaders (Wran, Unsworth and Carr), and, in the century since Jack Lang took over in 1923, only ten.

On current indications, the latest incumbent, John Brogden seems unlikely to break the mould, although nothing is certain in politics. He’s young enough to serve 30 years as Premier like Tom Playford in SA.
