An increased number of people were tested for COVID-19 on the weekend.
The slight increase came after it was revealed a Brauer College student and a Lyndoch Living employee returned positive tests.
South West Healthcare COVID coordinator Sue Anderton said there had been a slight increase in demand for testing in the past week.
"We are working with Brauer College to get close contacts tested," Ms Anderton said.
On Saturday, there were 129 people tested at the city's testing centre, while on Sunday there were 228.
That was an increase from 97 on Friday.
South West Healthcare has revealed there have been no new COVID-19 cases detected in Warrnambool.
That is despite a Brauer College student and a Lyndoch Living employee who has no no contact with residents or clients testing positive to coronavirus in recent days.
"Due to the interest in new local cases over the weekend, South West Healthcare has decided to provide this reassuring update to the community today," the service said in a statement.
Across the south-west there are a total of 10 active cases.
This includes two in Warrnambool, one in Moyne Shire, three in Corangamite Shire and four in the Glenelg Shire.
The COVID testing clinic in Merri Street is open from 8am to 4pm.
Testing is via appointment only.
A number of Brauer College parents have been notified their child is an education contact after a student tested positive to COVID-19.
The student has been kept home and is isolating following the result, Brauer College Principal Jane Boyle said on Friday night.
"A student who attends Brauer College has been notified that he has the COVID-19 virus," Ms Boyle told staff, students and parents.
An education contact is defined as someone who went to school and childcare and spent time with someone who has COVID-19.
"Education contacts will require an immediate standard (PCR) test," parents of education contacts were told.
"If the test returns a negative result, the student can return to school, with evidence of the negative result provided to the school."
The parents were told South West Healthcare had been advised and was preparing for a large number of tests.
"They have indicated they would prefer parents/carers to bring their child to the Merri Street drive-through testing site," parents were advised.
The student with COVID-19 attended school on Monday, November 22 and Tuesday, November 23.
The school remains open, with cleaning and contact identification completed on the weekend.
Meanwhile, there are a further two COVID-19 cases linked to the Hamilton cluster.
Two new cases were identified on Sunday, bringing the total number to 36.
"The two new cases are household contacts of a positive case who attended the event," a Western District Health Service spokesman said.
"Thirty local cases are now being monitored through the WDHS Hospital in the Home (HITH) program."
