Health authorities in NSW are also investigating whether an illegal party at a Lake Macquarie beach north of Sydney is the source of the state's Central Coast outbreak.
Some attendees are believed to have breached coronavirus restrictions by travelling from locked-down Sydney to Blacksmiths beach, about 25km south of Newcastle.
Mr Andrews announced the stay-at-home orders in Victoria would begin at 8pm on Thursday and last for seven days.
The announcement was made after the state recorded eight new cases of the highly-contagious Delta variant of the virus.

One of those infections is the housemate of a warehouse worker in the outer-west suburb of Derrimut whose case was reported on Thursday.
The housemate is a cleaner who worked at the Epworth Hospital in Richmond, Health Minister Martin Foley said on Friday.
