A fourth person has tested positive to COVID-19 at the Hamilton drive-thru clinic, bringing the total number of positive tests in the south-west to about 11
Four people have also tested positive in Warrnambool, and there is one confirmed case in each of the Glenelg, Corangamite and Moyne shires.
Under the reporting requirements, cases are listed by the department based on their place of residence, rather than where they tested positive, so while people may have tested positive in the south-west they may not live in the area.
The man who tested positive at the Hamilton drive-thru on Sunday lives in a neighbouring shire and has been in home isolation since returning from the UK recently.
On Friday, a third person - the partner of a man who tested positive to COVID-19 earlier last week - was found to also have the virus.
Both of those, who have mild respiratory symptoms, were in self-isolation together, after they too had returned from the UK.
The drive-thru clinic has screened more than 200 people, with 103 of those swabbed for the virus.
Western District Health Service chief executive Rohan Fitzgerald is asking people to do whatever they can to keep others safe, and the services has launched a 'voluntary lockdown' social media campaign to promote doing the right thing across the Southern Grampians.
"The majority of people seem to be making good choices to keep themselves and others safe, however the message still isn't getting through to some," Mr Fitzgerald said.
"We know that over the weekend several parties and other gatherings had to be shut down by local police, so we need to keep talking about what we all need to do to protect our community.
"New government restrictions of only two people (other than immediate family) being allowed out in public will assist, but we absolutely need to ensure that we are only going out for essential activities.
"If you can work from home, please do. If this is not possible, do whatever you can to maintain social distance and wash hands regularly at work.
"I recognise how difficult it is for people to change their behaviours overnight, but your actions now will save lives."
Mr Fitzgerald last week warned that it was only a matter of time before we see community transmission in our local area.
