From this weekend Victoria Police can now issue on the spot fines to people and business who don't follow the rules.
Businesses could be hit with fines up to $9913 for failing to comply to new restrictions.
State government police and emergency services minister Lisa Neville made the announcement on Saturday morning.

"We have seen the biggest overnight increase in infections since this started in Australia," Ms Neville said. "These measures are more important than ever.
"It gives the police an additional tool. That tool of on-spot-fine means people will understand the consequences of their actions. Heed the message or police can fine, arrest or detain you."
Ms Neville said the new measure were introduced because too many people were failing to take coronavirus seriously and putting lives at risk.
People can now be fined on the spot for fail to self-isolate for 14 days after returning from overseas to Victoria, organising or attending a mass gathering, attend a wedding beyond the persons being married, the celebrant and the witnesses, attending a funeral that has more than 10 people or arranging an auction for the sale of a residential property.

"We sincerely hope that Victoria Police does not have to issue one of these fines, and people do the right thing," Ms Neville said.
"For those who are at most risk of contracting coronavirus, please, if you can stay home, you must stay home."
