Victorian police could be able to remotely add, delete and copy data in a computer if they think it could prevent a terrorist act.

This capability is among a range of new powers tabled in state Parliament on Tuesday aimed at boosting the ability of law enforcement to investigate suspected terrorists.

Tweaks to covert search laws were among 13 recommendations in the review of counter-terrorism legislation that was led by former County Court judge David Jones, retired Lieutenant-General Mark Evans and former Victoria Police deputy commissioner Kieran Walshe.

The government supported 12 of the 13 proposals, including the amendment of the Terrorism (Community Protection) Act of 2003 to clearly allow police to remotely access data on a target's computers.

The provision should allow the Supreme Court to issue a search warrant to police to collect data that would "substantially assist" in preventing a terrorist act, the report stated.
