This year Tasmania controversially had Legislative Council elections on the same day as a House of Assembly election, for the first time ever. With the election being called for May 1st on March 26 with no prior warning the Tasmanian Electoral Commission had very little time to adapt to the logistic challenges of some voters having to vote in both houses. These voters were the voters in the eastern Launceston division of Windermere, which occurs entirely within the Assembly division of Bass, and voters in the large division of Derwent, which is mostly spatially in Lyons but includes many voters in the northern suburbs of Glenorchy within Clark.
The initial controversy around the holding of the elections on the same day concerned potential unfairness to candidates. Party candidates could benefit from generic party funding for the Assembly campaign while independent Legislative Council candidates were restrained by the Council's strict spending caps. There were arguments about whether parties could even legally run generic campaigns without in the process incurring expenditure on behalf of their Legislative Council candidates, though so far in terms of post-election challenges this aspect has not come to anything. As it happened voters voted quite differently in the two houses, so while the Lower House campaign may have distorted the Upper House outcomes, there isn't any clear sign that the latter are different to what would have been expected anyway.
