The latest daily update from the Department of Health and Human Services shows of the total 2231 cases in Victoria, 252 have been in regional Victoria.
Of these five have been in Ararat and three each in Horsham and the Northern Grampians. Yarriambiack and West Wimmera Shires have one recorded case each. None in the region are active.
There were 73 new cases recorded overnight, the fifteenth consecutive day of double-digit case growth in Victoria.
There have been 301 confirmed cases of coronavirus in Victoria that have been acquired through unknown transmission. There are currently 370 active cases in Victoria.
12pm: Another 73 coronavirus cases have been recorded in Victoria, as suburbs head into localised lockdown.
Three of the cases are from hotel quarantine, nine are associated with known and contained outbreaks, 19 were found through routine testing and 42 remain under investigation by the public health team, Premier Daniel Andrews confirmed on Wednesday.
Dozens of suburbs re-enter lockdown from midnight as a result of the community outbreak and two weeks of double-digit case numbers.
The following postcodes will be sent into lockdown until at least July 29:
- 3012 - Brooklyn, Kingsville, Maidstone, Tottenham, West Footscray
- 3021 - Albanvale, Kealba, Kings Park, St Albans
- 3032 - Ascot Vale, Highpoint City, Maribyrnong, Travancore
- 3038 - Keilor Downs, Keilor Lodge, Taylors Lakes, Watergardens
- 3042 - Airport West, Keilor Park, Niddrie
- 3046 - Glenroy, Hadfield, Oak Park
- 3047 - Broadmeadows, Dallas, Jacana
- 3055 - Brunswick South, Brunswick West, Moonee Vale, Moreland West
- 3060 - Fawkner
- 3064 - Craigieburn, Donnybrook, Mickelham, Roxburgh Park, Kalkallo
"There will be 12 new sites that will be dedicated testing locations across all of those postcodes that have been locked down from midnight tonight," Premier Daniel Andrews told reporters.
"This is not over. It won't be over for a long time and the best and most important thing that we can all do, whether we are in one of these hot spot postcodes or not, is to follow the rules."
In the week since a doorknocking information blitz started in Melbourne's northern and western suburbs due to the outbreak, about 54,000 homes had been reached and 113,000 tests done.
The majority of Victoria's new cases are due to community transmission, prompting Mr Andrews to reintroduce stay-at-home orders for 10 postcodes from Thursday until at least July 29.
Those postcodes are: 3038, 3064, 3047, 3060, 3012, 3032, 3055, 3042, 3021, 3046.
Much like earlier stage three restrictions, residents of the postcodes will only be able to leave their homes for four reasons: to shop for food and supplies, to receive or provide care, to exercise and study or work if they can't do so from home.
