MELBOURNE (REUTERS) - Police in Australia's coronavirus hot spot state of Victoria stepped up patrolling on Saturday (Oct 3) as hundreds of people in the city of Melbourne breached stringent lockdown restrictions and flocked to beaches on the warmest weekend in months.

Under the restrictions, nearly five million people in Melbourne, Victoria's capital, may exercise or socialise outdoors for a maximum of two hours a day, but must stay close to home. People must wear masks in public places.

But television and social media footage showed crowds, many people without masks, at some of Melbourne's beaches as temperatures soared ahead of summer in the southern hemisphere.

"A number of fines were issued to people who breached directions.... and Victoria Police will be conducting increased patrols of popular public spaces this weekend," police said in a statement.

Fines for not wearing masks reach A$200 (S$195) and for breaching public health orders are more than A$1,600.

Victoria Premier Daniel Andrews said the behaviour of the beachgoers was "unacceptable".

"Spending time at the beach without a mask, without social distancing now, will just mean that you won't get to go to the beach for all of summer," Mr Andrews said at a televised briefing.

State officials said eight people had been diagnosed with the coronavirus in the past 24 hours and three more people died. The numbers have been going steadily down after reaching more than 700 in new daily cases at their peak in July.

Melbourne has been under a strict lockdown for months, with the measures set to remain in place until the average number of new daily cases over a two-week window falls below five. On Saturday, it was 12.

Victoria, Australia's second-most populous state accounts for 90 per cent of national Covid-19 deaths.

Australia, with 893 fatalities, has fared far better than many other developed countries.
