Portland District Health service, CEO, Chris Giles has confirmed three new cases of Coronavirus has been detected.
These cases are close contacts of a person who received a positive test on Sunday.
There are now 12 active cases in the Glenelg Shire.
The latest cases have prompted huge demand for testing. Portland District Health CEO Chris Giles asked people to be patient while waiting to be tested.
PDH has developed an efficient no appointment drive-through testing site but Ms Giles said demand exceeded expectations and had left some people waiting for more than two hours.
The drive-through testing station will be opened this Thursday and Friday from 9am - 4pm. No appointment is required but people are asked not to rush the service at 9am.
