Landslide Planning Map Update

The Landslide Planning Map shows the distribution and relative susceptibility of landslides in Tasmania and underpins the state’s planning and building regulations. The map also forms the basis of the communication of landslide hazard risks to the public, through the Tasmanian Government’s Risk Ready information portal and tools that are publicly available through TasALERT.

The 2025 Landslide Planning Map has been updated from the one first developed in 2013. The 2013 Landslide Planning Map was developed to inform the development and application of landslide (or landslip) planning and building controls in Tasmania. The project to review the 2013 Landslide Planning Map was directed by the Minister for Planning with the following Terms of Reference. The review has led to:

  1. Proposed amendments to the Landslide Planning Map that consider and incorporate improvements in scientific methodology and new data;
  2. A review of the rankings and thresholds for the Landslide Planning Map - Hazard Bands – Acceptable, Low, Medium, Medium-Active and High; and
  3. A new Recent or Active Landslides system, which provides a mechanism to more readily incorporate information about newly-identified and expanding areas of landslide into Tasmania’s planning and building controls.

The review was undertaken between February 2024 and December 2025, with consultation on the proposed updates being undertaken in 2024. An external technical review of the outputs was conducted in 2025. The review endorsed the mapping and verified that it remained true to its intended purpose, and provided recommendations for future updates to the mapping. The reviewers' feedback was addressed before finalising the mapping or reporting outputs. The endorsement statement can be found in the foreword of the technical report and the key recommendations for future updates on page 39.

The new mapping will eventually replace the existing statutory mapping. MRT is working with the State Planning Office to facilitate this process and identify avenues for it to be used in place of the existing landslide planning overlay until the statutory process can be concluded.
