Government keen for a cybersecurity safe harbour law to protect businesses under attack

The government is keen for "safe harbour" laws that would "temporarily shield companies from liability during a cyber-attack", as a report by the Australian Signals Directorate says that its efforts to help businesses with cyber-attacks are "being hampered by lawyers, who are concerned about future regulatory actions from the government". This is backed up by the Business Council of Australia, who want to cut down the time wasted by businesses "vetting" information before handing it off to "ensure it cannot be misinterpreted by the plethora of existing regulators and government agencies". I was gonna blast the businesses asking for this as they could simply follow the law and not worry about getting in trouble if they're hacked, but knowing the government, any cybersecurity related laws are probably difficult or impossible to practically implement.
