Victoria will keep its South Australian border open as a coronavirus testing site is to be set up for interstate truck drivers.
The Department of Health and Human Services also has asked South Australians to cancel all non-essential travel to Victoria.
As SA deals with its outbreak crisis, on Wednesday Victoria reached 19 days without any deaths or new cases.
There are three active cases and 17,354 people were tested in the previous 24 hours.
Yesterday there were no new cases and no lost lives reported. Three active cases remain, none with an unknown source. 17,354 test results were received, thank you Victorians, #EveryTestHelpshttps://t.co/eTputEZdhs#StaySafeStayOpen#COVID19VicDatapic.twitter.com/WF3UbRZh2W— VicGovDHHS (@VicGovDHHS) November 17, 2020
Victorian Health Minister Martin Foley said on Wednesday morning that the SA border status is being reviewed hourly.
"We have no plans to close our borders, but we are monitoring literally on an hourly basis the situation in SA," Mr Foley told Channel Nine.
"Of course, we reserve the right to take further measures if the advice changes."
A testing site will be set up in Nhill, near the SA border, and will start on Thursday.
"The SA government has asked us to assist when it comes to testing, particularly of interstate truck movements," Mr Foley said.
Mr Foley also backed the Victorian contact tracing system, which came in for much criticism during the state's second wave.
"Our contact tracing system is now excellent," he said.
"It has been tested like no other system across the country, whether that be in the Shepparton outbreak, the northern suburbs outbreak, the Kilmore outbreak.
"We are sharing those learnings with all the other jurisdictions and we're seeing a lot of those learnings applied in SA now.
"I've got to say, the South Australians are doing a fantastic effort."
A screening process has been instituted for every SA arrival at Melbourne and Mildura airports.
Names and details of 122 passengers aboard two flights to Tullamarine on Monday were recorded and 81 of those tested, with more planes expected to land on Wednesday.
It comes as Chief Scientist Alan Finkel will give evidence at a parliamentary inquiry into Victoria's contact tracing system on Wednesday.
Dr Finkel has been advising the state government since August on modernising and digitising its processes.
Cedar Meats owner Tony Kairouz will also appear before the inquiry. The abattoir was the site of the largest outbreak of Victoria's first wave and put the spotlight on the state's contact tracing system.
The state's virus death toll stands at 819, with the national figure 907.
