Hundreds of people confirmed to have Covid-19 in Australia's worst-hit state have been caught flouting stay-at-home orders, authorities said, prompting tougher fines.
The southern state of Victoria is experiencing a rise in infections over recent weeks that the government has partly blamed on people breaking rules that restrict travel.
Residents of Melbourne, Australia's second biggest city and the capital of Victoria, are now under an overnight curfew, non-essential businesses are closed and face coverings are mandatory as hundreds of new cases are recorded daily.
But 800 infected people were not at home when authorities conducted recent checks, which state Premier Daniel Andrews called "completely unacceptable".
