The latest CommBank ranking of states and territories' performance across a series of indicators puts Tasmania at the bottom of the pack, where it has been for all of 2026.
Treasurer Eric Abetz says the government's investment in projects such as the Hobart stadium and Launceston Convention Centre will ensure the Tasmanian economy remains resilient "in the face of economic headwinds".
Tasmania has ranked last in CommBank's latest State of the States economic report, a decline from four years ago when it repeatedly topped the ranking.
The quarterly report, produced by the Commonwealth Bank of Australia, measures six economic indicators and compares states and territories' performances to their decade average or norm.
States and territories are measured on how much they have improved against themselves.
Wage growth has slowed, and total labour income is slowing more than any jurisdiction except for Western Australia and the ACT.
Business investment grew, while investment in housing fell by 6.2 per cent.
Public demand ranks last, but the recent figures are distorted because of the purchase of the new Spirit of Tasmania vessels.
The only positive indicator was household consumption, which was up by 2.1 per cent, giving Tasmania its highest rank of fourth place.
Four years ago, Tasmania was regularly topping the State of the States report, and even when it did not land on top, it claimed top position in some performance indicators.
Referencing the Liberal government's earlier claims that the report "proved their economic plan was working", Labor Shadow Treasurer Dean Winter said the latest CommBank report showed the opposite.
