South West Healthcare's COVID coordinator Sue Anderton said the current outbreak now spanned across eight households.
Chief executive officer Craig Fraser added one of the five COVID-positive people that had been re-directed out of the region is in hospital.
"I think there's one in hospital and three or four in quarantine," he said.
"That'll alter as time goes on. Once again as a health service, our focus is on the wellbeing of those with COVID. We will be transferring them to Melbourne or to Barwon, whichever is the best hospital at the time, if in doubt.
"So it's not necessarily anything to be too concerned about but if in doubt we will try and get those people to a hospital sooner rather than later."
Mr Fraser said elective surgeries had been paused since last week and a decision on its return would be made in the next day or two.
"I don't have a time-frame, it's a wait and see," he said.
"We've suspended this week and last week and we'll make a decision in the next day or two. It's two-fold - we want to make sure we want to reduce the flow in the hospital and also we want to make sure we have the staff to respond should we see another spike."
Health authorities say COVID-positive people are being asked to contact their secondary close contacts themselves.
It comes as Victorian chief health officer Brett Sutton said yesterday Tier 2 exposure sites would no longer be listed on the website.
Two new COVID cases have been recorded in the south-west overnight, including one in Warrnambool and one in Moyne Shire.
In a statement, South West Healthcare said the new cases were in two separate households and were both linked to the current outbreak.
Both COVID-positive individuals are isolating at home.
Today's two new infections takes the number of active cases across the Warrnambool and Moyne Shire LGAs to 20. Three are in Moyne and 17 are in Warrnambool. All are isolating.
There have been 26 cases recorded in the two LGAs in total.
