On ClimateNest's 0–10 suburb hazard index, Avon scores 3 for flood risk — a lower exposure relative to the Australian suburb range. For comparison, properties in Avon can still sit well above or below this suburb average depending on elevation, distance to waterways or vegetation, and local drainage.
