Victoria's Minister for Planning Richard Wynne said a new planning scheme amendment was put in place on Wednesday that "really removes all hurdles to any hospitality venue that has already a permit for outdoor dining".

"This is important because we know that there's a huge appetite for hospitality not just in the CBD but across metropolitan Melbourne and regional Victoria," he said during a press conference.

"This planning scheme amendment is for the whole of Victoria. The opportunity is there for any hospitality venue that wishes to expand its legal operation to do so without any hurdle in its way.

"We know also that from the point of view from consistency of applications, this is really important."

Mr Wynne said the planning scheme amendment would be in place for an initial 12-month period.

"This may well be the future of our planning deals with these outdoor applications going forward," he said.

He said hospitality industries could push their existing dining out to the street or expand their operation by creating "pop-ups" in car parks.

The announcement came after Victoria recorded three new coronavirus cases overnight and no deaths.

Melbourne's 14-day average of new cases has fallen slightly to 6.2.

Regional Victoria remains on 0.4.

The number of cases in Melbourne with an unknown source has fallen to 10, from 13 yesterday.

Premier Daniel Andrews said there were 106 active cases in metropolitan Melbourne and three in regional Victoria.

The regional cases are all located in Greater Shepparton.

Mr Andrews said that a person who tested positive for the second time on Tuesday was being considered as having been reinfected with coronavirus.

"The person from yesterday who tested positive twice, the first time back in July, he is currently regarded as a reinfection of coronavirus, so he will be recorded as a positive case," he said.

"We have spoken a little bit about an expert panel to sit and look at all the detail of these complex cases and I can confirm that they have reviewed this particular case and concluded there wasn't enough evidence to say that the positive test presented viral shedding.

"The case is being monitored closely, and it is through an abundance of caution that we are assuming that is a positive case, rather than the person shedding after the original infection."
