Medibank Data Breach Class Action

Medibank Data Breach Class Action

Omni Bridgeway is co-funding a class action against Medibank on behalf of individuals who were affected by the Medibank data breach which occurred on or about 12 October 2022.

On 1 August 2023, the Federal Court of Australia ordered that two class actions against Medibank be consolidated into one set of consolidated proceedings known as Zoe Lee McClure v Medibank Private Limited (ACN 080 890 259) (VID64/2023) (Consolidated Class Action).

Omni Bridgeway is co-funding, along with Balance Legal Capital,  Baker McKenzie (an Australian Partnership) as the Law Firm on the record for the Consolidated Class Action.

If you are a current or former Medibank or ahm customer and have been affected by the data breach you are invited to sign up with Omni Bridgeway 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 Consolidated Class Action is being funded by Omni Bridgeway and Balance on a “no win, no pay” basis in accordance with the terms of a funding agreement or terms imposed by the Court. If the Consolidated Class Action is successfully resolved and there is a recovery of compensation, Omni Bridgeway and Balance will be entitled to reimbursement of their costs of the Consolidated Class Action that they have 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 Consolidated Class Action. Class members do not have to pay anything in the event that the Consolidated Class Action is unsuccessful, as Omni Bridgeway and Balance agree to pay any legal costs that might be awarded to Medibank or any other respondents.

Am I Eligible to Join this Consolidated Class Action?

Individuals who hold a current or former health insurance policy or are named on a health insurance policy with either Medibank or ahm and received a disclosure notification on or about the 12 October 2022 in relation to the data breach are invited to register their claim with Omni Bridgeway. 

How Do I Sign Up?

It is currently proposed to bring the Consolidated Class Action on an ‘open’ basis, that is, on behalf of all individuals who were affected by the Medibank data breach which occurred on or about 12 October 2022, whether or not they sign up to the funding agreement. If you do not wish to take part in the Consolidated Class Action, you will need to opt out in accordance with the relevant court rules.

Omni Bridgeway encourages all group members who do not wish to opt out to sign up so that Omni Bridgeway can include you as ‘known’ funded group members and ensure you receive regular updates regarding the Consolidated Class Action and, most importantly, so that any distribution from the proceeds of the Consolidated Class Action to which you may be entitled is properly paid to you.
