There were also only 11 new cases as Melbourne's 14-day case average dropped to 34.4, while the regional figure came in at 1.6.
This is the lowest daily Covid-19 case number since the start of the second wave of infections in the state.
The decline in case numbers is a "cause for great optimism and positivity right across metropolitan Melbourne", Premier Daniel Andrews said on Sunday after 14 cases were reported.
"That is proof positive beyond any question that this strategy is working," he said.
Melbourne's daily average is well below the target of 50 to lift some virus restrictions later this month.
Mr Andrews said the path towards easing rules was being constantly reviewed.
"There's no good opening up too early. There's no good letting our frustrations get the better of us," he said.
"All that will mean is that everything metropolitan Melbourne has given, everything that everyone has done to produce these low, but still not low enough, numbers will count for nothing."
Optimism has risen among Melbourne small businesses, with a survey showing 35% now believe the Victorian economy will be better in one year's time.
That compares with just 17% in August believing the state's economy will improve by then, the latest Sensis Business Index showed.
More also think the national economy will mend, with 26% saying it will be better in a year compared with 14% last month.
Despite the premier's upbeat tone, frustrations were evident on Sunday as anti-lockdown protests continued in Melbourne.
More than a dozen protesters illegally gathered at Chadstone Shopping Centre and belted out a rendition of John Farnham's You're The Voice before police intervened.
Two people were arrested and six were issued fines hefty fines, adding to Saturday's 16 arrests and 21 fines after up to 100 people rallied in Melbourne's inner beachside suburb of Elwood.
