There were 295 new cases and nine deaths confirmed in Victoria on Wednesday morning.
Premier Daniel Andrews said more than 18,000 tests were conducted across the state yesterday, with 9304 confirmed cases on Wednesday.
"That is 295 more than our last update," he said.
Mr Andrews said there were nine further deaths, including two people aged in their 90s, five in their 80s, one in their 70s, and one in their 60s.
He said there were 307 people in hospital with the virus and 41 in intensive care.
He said there were 195 active cases in regional Victoria.
A break down of cases is expected to be given later today.
It comes just days after Victoria recorded its highest singe-day total (532 new cases) on Monday.
Mr Andrews thanked the community for doing the right thing.
"I am so grateful for regional Victorians who continue to do the right thing to keep those numbers low," he said.
"I just want to reinforce the key message - if you're sick, you cannot go to work.
"If you're sick, you cannot go to the shops. If you're sick, there's only one thing to do, to get tested and get tested quickly."
Mr Andrews said people must stay home until their test results were revealed.
"And if you are positive, you need to isolate at home for a further 14 days," he said.
"These are very simple things."
Prime Minister Scott Morrison said Victoria's testing regime "continued to run at a cracking pace".
He said the Australian Defence Force (ADF) would continue to door-knock those who have tested positive to COVID to bolster the state's contact tracing.
ADF personnel last week joined state health officials in special teams to contact people who have not been reached by phone.
The aim is to ensure all positive cases are contacted within 24 hours of receiving their test result.
Mr Morrison said the "Victorian wave" was affecting other states and "impacting the national economy more broadly".
"Australia wins when Victoria wins," he said.
"It's in the national interest, not only from a health perspective but from an economic perspective. We all back Victoria to win and we're doing everything we can to ensure they do that."
Mr Morrison welcomed Premier Andrews' decision to suspend category two elective surgery and thanked local hospitals for working so quickly with the federal government.
"That is already making a very big impact," he said.
