Victoria has had no coronavirus deaths and only three new cases.
Melbourne's daily case average dropped to 6.2 and the mystery cases from October 5-18 also fell to 10.
The corresponding figures for regional Victoria remain steady at 0.4 and none.
The state's death toll remains at 817 and the national figure is 905. Victoria has had only one death in the past week.
All the new cases are in Melbourne, with two related to the northern community outbreak and the other under investigation.
Also on Wednesday, Premier Daniel Andrews confirmed that Tuesday's sole positive case was being treated as a rare reinfection.
It had been unclear whether the man was shedding the virus he had caught in July but the premier said an expert panel had reviewed the case and determined he had been reinfected.
"The case is being managed very cautiously," the premier said.
There are 109 active cases in Victoria and the three regional positives remain the greater Shepparton outbreak from last week.
The good news comes as Victorian government has backflipped over its controversial call to allow a select group of spectators on course for the 100th running of the Cox Plate, following intense political and online backlash.
Racing Minister Martin Pakula apologised after just hours earlier announcing up to 500 racing connections would be able to attend Moonee Valley for Friday night's Manikato Stakes and Saturday's Cox Plate.
He said he'd spoken to the Moonee Valley Racing Club on Tuesday night and the decision had been reversed.
"It was a mistake, given that other restrictions remain in place and we've heard the community feedback," he tweeted.
Ellen Sandell, acting leader of the state Greens, branded the original decision a kick in the guts to Victorians after months of being unable to see family, go to funerals, have visitors at the hospital or open their businesses.
"It seems to be one rule for them and another rule for the rest of Victoria," she said in a statement.
COVIDSafe arrangements including a 1000-person course cap, staggered arrivals, temperature checks, social distancing and takeaway only food and beverage services had been planned.
Mr Pakula had earlier noted the Victorian government had "taken the advice of the chief health officer" when making the change.
Opposition Leader Michael O'Brien questioned why that advice was now being "ignored" following the reversal.
"What a shocking pack of frauds," he tweeted.
It comes as Premier Daniel Andrews says the state is well placed to bring forward the further rule easing slated for November 2, which includes the reopening of retail and hospitality industries in Melbourne.
"It's very important that we see this thing off properly, so Sunday will be a day where we can have more to say," he said.
On Tuesday, the leaders of seven major businesses, including Wesfarmers, Commonwealth Bank, BHP, Orica, Incitec Pivot, Newcrest and Coca-Cola Amatil sent a joint letter to Mr Andrews pleading for him to allow businesses to reopen.
"We urge you now, in light of the excellent recent progress, to permit the careful and staged return to the workplace of office workers and the small businesses that provide services to them," they said in the letter cited by the Herald-Sun.
