|---|---|---|---|
| Eyre Peninsula | 655 | 561 | 86% |
| Kangaroo Island | 24 | 24 | 100% |
| Lower Murray | 25 | 25 | 100% |

Based on current conditions, the risk of further insulator pollution interruptions this season is now assessed as low.
Our emergency operational response is now easing, but the work to address insulator pollution continues. Our focus now shifts to longer-term remediation in each affected region to reduce the likelihood of similar outages next summer and beyond.
