Tasmania is currently undergoing a redistribution of its federal boundaries – the second of six federal redistributions due during this parliamentary term. The boundaries will also apply to Tasmanian state lower house elections, but probably not until the 2022 state election.
The draft boundaries were released earlier this year, and they saw a few significant changes. The seat of Bass, which covers most of the Launceston area, retracted in to just cover areas surrounding the Tamar river, losing the north-eastern corner of the state. Lyons underwent changes in a number of areas.
It is standard practice for federal redistributions to go through two rounds of suggestions and comment, followed by the release of a draft map, then two more rounds of objection and comment, followed by the release of the final boundaries. This time, however, the AEC has chosen to open up another round of objections and comment, as the boundaries released today were significantly different to the first draft.
No changes were made to the boundaries of three of the five seats, but there were significant changes to the Bass/Lyons border. Bass regained the Dorset and Flinders council areas in the north-eastern corner of Tasmania, and lost the small part of the Meander Valley council area contained within the Launceston urban area. This area was contained in Bass at least since 2001.
At the other end of the state, the Hobart-area seat of Denison has been renamed Clark, after Andrew Inglis Clark: state Supreme Court justice, Attorney-General and one of the inventors of the Hare-Clark voting system. This followed a campaign to change the seat name, including from sitting MP Andrew Wilkie and his predecessor Duncan Kerr.

I’ve seen some commentary expressing frustration about the removal of the urban parts of the Meander valley from Bass, sticking them in an electorate which stretches to the edge of Hobart.
Unfortunately it isn’t possible for Bass to contain both the Meander Valley area and the Dorset/Flinders corner without pushing Bass over quota.
Based on projected 2021 enrolment figures, Bass must lie within 3.5% of the average. In real numbers, they must have between 74,289 and 79,677 projected enrolment. Bass is projected (as drawn) to have 75,653 voters.
There are three areas which have been moved between Bass and Lyons – the Meander Valley area on the south side of Launceston, the Dorset/Flinders corner of the state, and the West Tamar area which was moved from Lyons to Bass in the original draft and remains there. Each has between 5867 and 7828 voters as of 2021, and if all three were included in Bass it would be more populous than is permitted.
So the original Redistribution Committee decided to make Bass more of a Launceston-based electorate, moving the rural north-east into Lyons, and the augmented Commission has instead decided to make Bass follow local government areas, leaving part of the Launceston urban area in Lyons.
So now there is time for interested parties to argue the case. Theoretically they could also decide to completely reverse the Lyons-Bass border back to its previous boundaries, putting the West Tamar back into Lyons, but this is unlikely.
