The Warrnambool police coronavirus mobile application is on Monday showing no active cases in Warrnambool.
A police spokesman said the Operation Sentinel app was specifically for police force members to assist with COVID-19 tasking duties.
Those duties include checking Warrnambool business and residents are doing the right thing and at least 10 tasks are undertaken each day.
"There is no active case in Warrnambool, according to the app and no specific person to check," a spokesman said.
On Sunday, local government area figures showed there was one active case of coronavirus in Warrnambool.
The Department of Health and Human Services releases the data each day but details about the person who tested positive have not been revealed.
The confirmed case takes the city's total during the pandemic to six people testing positive.
There are 47 active cases in the Colac Otway Shire and six in Glenelg Shire.
It's expected that 800 people will be tested in Colac today.
There is already a long line of cars at the Central Reserve testing site.
Mid this month, an active coronavirus case listed in Warrnambool wasn't recorded at the city's South West Healthcare hospital, but authorities refused to release further details about the case.
DHHS said they wouldn't provide details about individual cases unless necessary in the interests of public health.
The testing procedure involves those taking the test given an address.
It's understood the last Warrnambool positive case was someone who has a Warrnambool address, like a student, but who was living in Melbourne.
