As for the Labor government that followed, I can't think of anything they achieved :).
They got the police to pull their heads in a bit. Queensland was a bit less safer if you were Aboriginal or a feral for a few years there.
Under Joh Queensland got: It's last significant new water dams, the Gateway Motorway, new International Airports, James Cook University, Queensland Cultural Centre, Griffith University, the South East Freeway, Captain Cook and Merivale bridges, World Expo 88, 1982 Brisbane Commonwealth Games, etc, etc.
Almost complete destruction of anything remotely historic or attractive in the CBD, the ugliest river bank fuckup in the known world (the riverside expressway). Oh, and a police state. Also, the Great Barrier Reef narrowly escaped turning into a collection of oil rigs.
And the cultural centre is one of the ugliest collections of buildings in Australia. More blind than visionary.
