The penalties for serious breaches of the Privacy Act would increase from 2.2 million Australian dollars ($1.4 million) now to AU$50 million ($32 million) under amendments to be introduced to Parliament next week, Attorney-General Mark Dreyfus said.

A company could also be fined the value of 30% of its revenues over a defined period if that amount exceeded AU$50 million ($32 million).

Dreyfus said “big companies could face penalties up to hundreds of millions of dollars” under the new law.

“It is a very, very substantial increase in the penalties,” Dreyfus told reporters.

“It’s designed to make companies think. It’s designed to be a deterrent so that companies will protect the data of Australians,” he added.
