Residents in regional areas have a right to know if there is an active COVID-19 case in the place they live, says Member for South West Coast Roma Britnell.
She has written to Victorian Health Minister Jenny Mikakos following confusion about where people who have returned a positive test live.
Ms Britnell said the lack of transparency over where people with the virus live was causing undue angst in the community.
"People feel when they are not being given information there is something to fear," she said.
"Information brings confidence - silence invokes fear."
Ms Britnell said people in regional areas wanted accurate up-to-date information about active cases.
A Department of Health and Human Services spokeswoman said the health of the community was the number one priority and information was delivered to Victorians as soon as it was available.
"When our LGA data reflects a new active case, residential location is the residential address provided when the case is notified," she said.
"This is not necessarily where the person was infected and may not be where the individual currently resides.
"Our LGA data is continually analysed and clarified as our contact tracing teams gather information - so published numbers will always be subject to change."
Ms Britnell said this response was insulting and the state government needed to do more to provide accurate locations of active cases.
Her call for greater transparency came after it was revealed the number of cases in the Glenelg Shire increased to eight and there have been 50 cases linked to the Australian Lamb Company in Colac - with 54 in total in the town. There is also an active case in Southern Grampians Shire.
Portland District Health chief executive officer Chris Giles urged people to get tested.
"COVID-19 has no vaccine and no cure, anyone who gets this virus is at risk of life long complications, or even death, I want to stop this virus moving insidiously through our community, but if I can't find the people infected I can't slow and ultimately stop the spread," she said.
There were a further six deaths in Victoria and 384 new cases.
Premier Daniel Andrews revealed non-urgent elective surgery was set to be suspended to deal with the growing number of people suffering from coronavirus.
He said there was a need to free up staff.
