Update 3pm: Despite the new "low positive", the overall total has not increased due to one case being reclassified.
Update 1pm: Chief Health Officer Brett Sutton said the single case recorded on Saturday was a "low positive",
While Premier Daniel Andrews took a break after 120 consecutive days of providing updates, Health Minister Martin Foley confirmed the positive case was a person in hospital who had previously tested negative several times.
Mr Sutton said the expert review panel would look into the test result on Saturday.
"We can get these indeterminate results or only a weak signal on the test and they are a normal part of testing," Mr Sutton said. "When you're doing 20,000-plus tests, you will get one or two.
"Previously, we would have had a couple every day but among dozens and dozens positive cases. We were not digging down to those results as we are now."
Mr Foley said there were only 71 active coronavirus cases in Victoria. None of those cases were in the regions.
There were only two people in hospital with COVID-19, although neither of those people were receiving intensive care.
Earlier: Victoria has recorded just one case of coronavirus overnight, and no new deaths.
It takes the total number of cases in the state since the pandemic began to 20,348, 19,381 of whom have recovered from the disease. The number of active cases is at 80.
The regional 14-day average has dropped to Zero, while Melbourne's is at 2.4.
The Department of Health and Human Services has reminded residents to stay COVID safe this Halloween with the following advice:
- If you have any symptoms of coronavirus (COVID-19) get tested and stay at home. By staying at home this Halloween, you help to keep your friends, family and community safe.
- Don't use communal bowls for lollies or candy, and place bags on your fence, at your front gate or outside your home for collection.
- Wear a face mask with your costume, but remember that a costume mask that is part of your Halloween costume is not a substitute for a face mask. Consider making your own mask and decorating it.
- Keep at least 1.5 metres between yourself and people you don't live with. This means no hugging or kissing when greeting people. Don't share food or drinks.
- Have a Halloween party outside in a public place. You can catch up with a group of up to ten people (including yourself). Babies under 12 months age aren't included in the ten-person limit. An outdoor public place means an area accessible to everyone, including local parks and beaches.
- Do a Halloween scavenger hunt by giving children a list of Halloween-themed things to look for as they walk outdoors from house to house admiring Halloween decorations at a distance. Just like eye-spy! The limit of ten people (including yourself) applies to scavenger hunts.
- Carve or decorate pumpkins with members of your household.
- Decorate your house.
- Have a virtual costume party or party with friends and family on video chat.
- Have a Halloween movie night with your household.
- Create an around the house trick or treat or scavenger hunt for your household
