(Reuters) - Australian health insurer Medibank Private said on Thursday it will isolate and remove access to some customer-facing systems as it detected unusual activity on its network.

The company said it took "immediate steps to contain the incident, and engaged specialised cybersecurity firms", adding that there was no evidence that any sensitive data, including customer data, had been accessed at this stage.
