Relative comparison
Standard home security is usually sufficient; the community is vigilant and well-connected.
The primary risks are environmental, specifically related to the Murray River's flood cycles and the surrounding bushfire-prone landscape.
High risk for properties below the 1956 and 2022 flood levels. Levee banks protect some areas but not all.
Significant risk in the 'Rural Living' zones surrounding the main township during summer months.
Can be difficult or extremely expensive to obtain full flood cover for low-lying riverfront allotments.
