The latest figures from Victoria's chief health officer Brett Sutton reveal a spike in the number of community acquired cases from 39 to 57.

More than 49,000 coronavirus tests have been conducted in Victoria, with 1036 positive results returned, an increase of 68 from yesterday.

There are 193 cases in regional Victoria, 828 in metropolitan Melbourne and the remainder under investigation.

36 people are in hospital receiving treatment for coronavirus, including six patients in intensive care and 422 people have recovered.

All people arriving from an international destination must self-isolate, with police able to issue fines to individuals who do not comply.

Stage 3 coronavirus restrictions include gatherings of no more than two people, except for members of your immediate household and for work or education.

The directions about staying home are now enforceable, with an on-the-spot fine of $1,652 for individuals and $9,913 for businesses.

Victoria Police says in the past 24 hours they have conducted 1084 spot checks at homes, businesses and non-essential services, issuing 13 fines as part of Operation Sentinel, to enforce stay at home, restricted activity and isolation directions.

23 fines have been issued and 10,292 spot checks conducted since March 21.

The state government has also struck a deal with Victoria's major private hospital operators to care for Victorians during the coronavirus pandemic.

The deal will see public and private hospitals work together to relieve pressure on public hospitals and ensure the entire health system is operating at full capacity and as one.

"Our whole healthcare sector has a vital role to play in fighting coronavirus - and this deal ensures we have one system of care," Minister for Health Jenny Mikakos said.

Premier Daniel Andrews also announced a $1.3 billion boost to the state's health system this week.

The funds will help establish an extra 4000 intensive care beds, increasing the state's current capacity of about 450 ICU beds across public and private hospitals.

The funds will also be used to purchase millions more masks, gloves and gowns.
