Non-credible contingency event more likely to occur due to existence of abnormal condition/s - SA region.

Conditions can change rapidly and potentially impacted plant may change. Further notices will only be published to advise of any reclassification, or when the abnormal conditions have ceased to impact the likelihood of a non-credible event occurring.
