While looking at a few of the larger Tasmanian councils in preparation for an interview I was surprised by how few incumbents were recontesting in some of the councils. Launceston, with only seven out of 12 recontesting, and Glenorchy with only five out of ten, especially caught my eye. Hobart with 11 out of 12 recontesting started to look unusual. I couldn't help wondering if the proportion of councillors throwing in the towel in Tasmanian local government elections was rising, and as if I didn't have enough to do, I couldn't resist investigating it.
This is what I found. The following numbers may have some slight errors (eg if I have been tripped up by a councillor's name changing without my knowledge) but any errors won't greatly affect the overall picture.
The 2014-8 term was the first four-year term for councils that was formed by all-in-all-out elections. The 2018-22 term has also featured all-in-all-out elections but a noticeable difference is that in the 2022 election, voting is compulsory. One council (Glenorchy) had its 2014-8 term shortened by several months and its 2018-22 term lengthened after an election was called early to fix a council that had become dysfunctional.
