Victorian premier Daniel Andrews has threatened heavy fines for anyone breaching Covid-19 isolation orders as the state ramps up stage 4 lockdown measures in Melbourne. Andrews confirmed an increased presence from the Australian Defence Force will be deployed to enforce the orders after more than 800 people who were instructed to self-isolate at home could not be located. Victoria police chief commissioner Shane Patton added officers have been 'baited' by people refusing to provide their name and address. 'We've had to smash the windows of people in cars and pull them out of there so they could provide their details because they weren't telling us where they were going,' he said
