Extremes in percentages of first preference vote for elected Tasmanian MHAs at polls since Hare-Clark began in 1909
Source data by courtesy of the Tasmanian Electoral Commission
Compare the Hare-Clark pattern below with the pattern for Senate elections, which shows much less evenness in the spread of first preference votes among the elected candidates within a party column than does Tasmania’s Hare-Clark system. The much greater control parties exercise for Senate elections is because the Senate’s PR system inherited the pre-existing REGIMENTED system of voting created by the listing of candidates’ names in each party column on the ballot-paper in the order the party determines. The Senate system became even more REGIMENTED in 1983 by the introduction of GROUP VOTING TICKETS. Tasmania’s Hare-Clark system has never let parties set the order of candidates’ names on ballot-papers. Its Parliament chose Robson Rotation instead, in 1979.
Note that the only case since 1909 of any MHA gaining an absolute majority of first preferences votes was Douglas Lowe, in Franklin, in 1979.

Robson Rotation began at the 1980 Denison poll the Supreme Court ordered. It is, unfortunately, not yet used in Senate polls, but it has applied for Australian Capital Territory Legislative Assembly polls since 1992. Order in a column was alphabetical until 1976, and by lot for 1976 and 1979. * Marks a sometime Tasmanian Premier.            # Marks the Denison by-election the Supreme Court ordered, declaring all 7 Denison seats vacant. § Until 1941 all candidates were in a single column. From 1941, party candidates were grouped, by mutual consent, in party columns designated by the name of the party, and all other candidates were in a single column at the far right of the ballot-paper designated as "Independents". The order, from left to right, of the columns across the ballot-paper has, since their introduction in 1941, continued to be determined by lot, and is not determined by Robson Rotation.
