The statement added that the company does not believe that customer or employee data has been compromised.

It said the company's network of 279 dealers is "still operational and able to help customers with their enquiries. However, there have been some impacts to parts supply, which is subsequently delaying servicing at some dealerships."

An emergency call centre has been set up to handle customer enquiries, including the Takata recall (number in Australia is 1800 462 000).

The statement also outlined a number of "facts" in relation to the hack:

"The facts:

1. At this stage, we do not believe that customer or employee data has been compromised.

2. We became aware of the attempted attack on Tuesday, 19 February 2019.

4. A number of corporate IT systems are still offline including email.

5. There has been no enterprise-wide directive to send employees home.

6. We have no further information about the origin of the attempted cyber attack."
