So what's the final tally exactly? The ABC website is stuck on 81-51.
http://vtr.aec.gov.au/The reason those four seats have no leader is not that they are super-duper-close (unlike the six listed just below) but that the relevant 2pp is not Coalition-ALP and they just haven't counted the actually relevant stuff yet.
Also, see here:
http://www.aec.gov.au/FAQs/election_results.htm#when (this "the AEC determines the names of the two candidates expected to come first and second in the election" thingy seems to automatically assume Coalition-ALP except where there is a third party incumbent or Coalition or ALP are not even standing. Hence, no "real" 2pp results on election night for Fairfax or Indi, but for Katter's seat as he is the incumbent.)
