If you are a current or former Medibank or ahm customer you are invited to register your details below.


Medibank Private Limited is an Australian public company listed on the Australian Securities Exchange under ticker code ‘MPL’, and also trades and issues insurance policies under the registered business name ‘ahm’ (together, Medibank). Medibank is engaged in the business of issuing private health insurance policies. 

On or about 12 October 2022, Medibank was the subject of a data breach, which reportedly involves millions of current and former Medibank, ahm and international student account holders.

The customer data that has been compromised in the data breach includes current and former customers' names, dates of birth, addresses, phone numbers and emails, some Medicare card numbers, some passport numbers and health claim data.

How Much Will it Cost to Take Part in the Class Action 

The class action is being funded by Omni Bridgeway on a “no win, no pay” basis in accordance with the terms of a funding agreement or terms imposed by the Court. If the class action is successfully resolved and there is a recovery of compensation, Omni Bridgeway will be entitled to reimbursement of the costs of the class action that it has funded plus a commission from the judgment or settlement amount, pursuant to the terms of the funding agreement.

There are no costs involved for group members who wish to take part in the class action. Class members do not have to pay anything in the event that the class action is unsuccessful, as Omni Bridgeway agrees to pay any legal costs that might be awarded to Medibank or any other respondents.
