West Coast ratepayers are encouraged to take note of changes to property valuation adjustment factors.
Council conducts a full revaluation of all properties every six years. In between those revaluations, the Valuer‑General’s Office applies adjustment factors every two years to reflect changes in market conditions, based on property sales and rental data. The current adjustments are based on data collected between 2 October 2024 and 1 October 2025.
These adjustment factors are not set by West Coast Council. They are determined by the Valuer‑General, with all councils in Tasmania going through this process.
How the adjustment factors work
Adjustment factors are applied to a property’s valuation as at the last full revaluation date. For rating purposes, the most significant figure is the Annual Assessed Value (AAV), which is what Council uses to calculate rates. Capital Improved Values are also adjusted but are not used to calculate rates.
In previous adjustment rounds, all West Coast properties were treated as a single group. This has changed in the 2026 adjustments, with Strahan and Zeehan now assessed as separate cohorts for vacant land. Back in 2024 the adjustment factors were as follows:
Vacant Land – Annual Assessed Value (AAV):
|
Locality |
Residential |
Commercial |
Industrial |
Primary Production |
|
General |
1.30 |
1.10 |
1.10 |
1.35 |
Other Property – Annual Assessed Value (AAV):
|
Locality |
Residential |
Commercial |
Industrial |
Primary Production |
|
General |
1.20 |
1.00 |
1.00 |
1.35 |
Capital Improved Value (Not used for rating purposes):
|
Locality |
Residential |
Commercial |
Industrial |
Primary Production |
|
General |
1.25 |
1.10 |
1.10 |
1.35 |
What has changed in 2026?
For vacant land in Strahan and Zeehan, the new adjustment factors result in an overall decrease of around five per cent across residential, commercial, industrial and primary production land when compared with the previous settings.
For vacant land in the rest of the West Coast, residential land shows an overall increase of around five per cent, while commercial, industrial and primary production land generally decrease by around five per cent.
For properties with capital improvements, the main change is a 10 per cent increase to residential Annual Assessed Values, with commercial, industrial and primary production properties largely unchanged.
Overall, these changes are not expected to cause significant redistribution of rates across the municipality
