Victoria Police will soon be equipped with enough firepower to combat terrorists under a plan devised by the force's top officials.

Police will be given access to military-style semi-automatic rifles to deal with high-risk incidents such as seiges and terror events, Fairfax Media reports.

The high-powered weapons will be locked away in police care with general duty officers able to use them before tactical police arrive at a scene.

The moves comes after police in New South Wales unveiled their new heavy arsenal in December last year.

Victoria Police are making the move in light of a string of terror-related incidents in the state last year including the Bourke Street rampage and the Flinders Street terror plot.

Officers in the Special Operations Group and Critical Incident Response Team already have access to these kinds of guns.

A senior police source told The Age a decision on the heavy weaponry was imminent.

"To enhance our abilities to respond to a major security incident or terrorism attack, we are currently scoping the potential use of a limited allocation of long-arm firearms to better support frontline police," a spokeswoman for Chief Commissioner Graham Ashton said.

"It not intended that police will patrol with rifles as part of their day-to-day duties. Victoria Police wants our members to be approachable. This additional tactical equipment, if we proceed with the project, would be safely stored and available for police to use if such an incident were to occur."
