Update, 5pm: A Warrnambool man who works at a Colac abattoir has re-tested positive to COVID-19, three weeks after he was diagnosed and then given the all-clear by the health department to return to work.
His partner has spoken out about what they have described as a "confusing" and "unjustifiable" handling of the virus by the state health department.
In the past week South West Healthcare has screened another 319 people for coronavirus, taking total screenings to 8270.
Update, 3pm: An active case of coronavirus has been recorded in Warrnambool, which has been virus-free for a week.
The Department of Health and Human Services data shows one new active case in Warrnambool, however the total case numbers have not increased.
On Wednesday there were six overall cases in the Warrnambool local government area and that number has not risen despite the new case.
It is not known if the person who has tested positive currently lives in Warrnambool or if they live out of the region but still have a Warrnambool address, such as a university student.
The Standard asked South West Healthcare if it was aware of the new case, but no information was available.
The Standard has also asked DHHS for more information on the new case.
Cases in Colac continue to drop, with cases dropping from 74 to 61 in 24 hours.
82 total cases have been linked to Australian Lamb Company in Colac.
There has also been a dramatic drop in cases in Glenelg Shire, with numbers dropping from 11 to five on Thursday.
Cases in Geelong have dropped slightly from 179 to 172, there is one less case in Bendigo at 52 and two more cases in Ballarat at 24.
There are five cases in Surf Coast Shire, 11 in Golden Plains Shire, three in Horsham, and one in Moyne Shire.
There are no cases in Corangamite Shire or Southern Grampians Shire.
Additional testing in regional Victoria as state records eight virus deaths, 278 new cases
Another eight Victorians have died from coronavirus, while 278 new cases have been recorded.
It's the lowest number of new cases since July 20, when the state recorded 275 cases.
The deaths bring the state's death toll to 275 and the national figure to 360.
One was a woman in her 50s, two men in their 70s, two women in their 80s, two men in their 80s and one man in his 90s.
Four of the deaths are linked to aged care outbreaks.
There are 664 Victorians in hospital and 37 receiving intensive care.
There have been 20,951 more tests conducted since yesterday and 107 more mystery cases uncovered without a known source.
Of active cases, 1140 are healthcare workers and there are 2018 active cases across aged care.
Premier Daniel Andrews said three more testing sites would be opened up in Geelong, Ballarat and Bendigo after 'significant' growth in the regional cities.
"Significant growth in Geelong, Ballarat and Bendigo are of concern and we are closely monitoring them to have fastest and most localised response," he said.
"Geelong has almost half of all regional cases. Ballarat has the highest growth rate in the past week. Bendigo, while stable, has a stubborn number of concerning and active cases.
"It is very important that we keep case numbers low."
There are 492 active cases in regional Victoria, compared to 7155 in metropolitan Melbourne.
"From tomorrow we will have a regional testing push in Ballarat Geelong and Bendigo," Mr Andrews continued.
"Three additional test sites will be opened up to support additional testing and we encourage anyone with symptoms to come forward to get tested.
"If you have even the mildest symptoms we ask you to come forward and get tested, you will make a really powerful contribution.
"In fact anyone across regional Victoria, if you have even the mildest symptoms please get tested.
"We need to be confident we are finding as much of the virus as we can."
He said existing testing sites in the three key areas will increase operation hours and staff.
Acting Deputy Chief Health Officer Allen Cheng said he felt the regional cases were under control.
"There are 176 cases in Geelong, a lot of those are attributed to outbreaks which are coming under controls, there's certainly some outbreaks and cases we don't know where they are coming from," he said.
"In Ballarat there's a smaller number, 23 cases over the last two weeks, and the sense is it's starting to come under control but again we encourage anyone in the community to get tested.
"In Bendigo there are 51 cases and a high proportion can be attributed to known outbreaks, we think it will come under control soon and play out a bit like Colac.
"Though we can't make assumptions about what will happen."
The coronavirus test isolation payment will be increased to $450 across the state.
