Department of Health Deputy Secretary Kate Matson said Victoria would no longer require secondary close contacts to isolate.
Ms Matson said with Victoria is no longer chasing COVID zero, forcing secondary contacts to isolate was no longer necessary.
"It will also make it easier for household members of primary close contacts to get groceries and work while the primary close contact is isolated away from the rest of the household," she said.
"There is a very important difference between someone who is known to have come into contact with a confirmed case, and then someone who has come into contact with that primary close contact. And the risk is different.
"This just recognises the changing risk and the changing environment that we are in, we are no longer chasing COVID zero in Victoria, and we have 17,000 active cases in Victoria at this point in time."
The authorities are still asking primary close contacts to isolate away from their family inside their home.
A text message will be sent to our 16,000 secondary close contacts this weekend to advise them of this change and release them from quarantine.
