Where can you find info on these (i.e. who the candidates were, how many votes each one got, etc)? Wikipedia only has info on a handful of them.
I got them from Wiki, OurCampaigns, and Howard's memoir. I know more about the Liberals than the ALP, so here are the lesser known Lib ones.
1967-8: DPM John McEwen exercises a Country veto on McMahon. The battle is between Hasluck and Gorton, Gorton campaigns aggressively and publicly, a first. Like Maudling in the UK, Hasluck was the initial frontrunner but blew it because he didn't actively campaign.
1969: From Howard's memoir. Gorton nearly blew the election and got multiple challenges, Howard doesn't say by whom.
1971: Gorton is blamed for a Senate massacre in 1970, continues FUBARing. Challenged by McMahon, ballot tied 33 apiece. Accounts differ as to whether he resigned or used his casting vote to oust himself.
1974: Fraser challenged Snedden. Howard claims the vote was 36-26 Snedden, though this was the last time the Liberals didn't publicly release numbers so we'll never know for sure.
1975: Fraser beats Snedden, IIRC 37-27.
1982: Fraser is challenged by Peacock, beats him 2-1 or 54-27. Howard becomes deputy leader here, with Fraser's endorsement.
1985: Peacock resigns when Howard is reelected deputy leader. Howard wins easily.
1990: Peacock resigns, Hewson beats Reith 62-13.
1993: Howard challenges Hewson, Hewson wins 47-30. In this election Costello loses his first run for deputy (made vacant by Reith's resignation) 45-33.
1994: Downer challenges Hewson, beats him 43-36.
1995: Howard acclaimed... with a lot of elbow grease.
