Businesses will be able to share private details with the government’s cybersecurity agencies to help fight back in the immediate aftermath of a hack, without the information being used against them in future investigations and damages claims, under laws to be introduced before the end of the year.

A suite of measures will be introduced by Home Affairs and Cyber Security Minister Tony Burke in a new Cyber Act later this year, after his predecessor Clare O’Neil unveiled a national cyber strategy at the end of last year. He will reveal a number of them in a speech at the second annual The Australian Financial Review Cyber Summit in Sydney on Tuesday.
