 On episode 24, Tanya Plibersek became the first panellist to appear on "Q&A" more than twice in one season (only if you consider 2009's programmes to be two seasons - both Tony Abbott and Joe Hockey appeared four times in the full year of 2009 with five other panellists appeared three times that year).Episode 27 and 28 each featured the two leaders alone on the panel, in the final two episodes before the election.Episode 29 was the first episode following the election, and was controversial in that at the last minute Julia Gillard pulled Mark Arbib from appearing on the panel, and an empty chair was left on the panel for the entire episode.
