A Holcim spokesman said all employees and contractors who were quarantined after the outbreak received a second test, with all results negative.

The second tests were carried out on the 11^th day of the 14-day quarantine period.

"We received approval from the DHHS to reopen last weekend but we wanted to make sure we received those results from the second round of testing first," he said.

"We tested 11 workers and 11 contractors all up because some of the contractors were part of other contracting companies which ordered there employees to undergo a test as a precaution.

"One of the workers who tested positive has recovered and has received a letter from DHHS that he can return to work while the other person is still in hospital and being cared for."

Holcim will conduct temperature testing at the quarry for anyone coming on site.

"That will be an additional layer to our already comprehensive COVID safe plan," the spokesman said.

Earlier, 11.40pm: Victoria has recorded 113 new coronavirus cases and 12 deaths overnight.

All the deaths have been linked to aged care and include a man in his 70s, two women and one man in 80s, and five men and three women in their 90s.

There are 513 Victorians in hospital, with 29 in intensive care and 17 on ventilators.

Premier Daniel Andrews said 19,863 more test results had been processed since yesterday, with testing turnaround sitting at an average of one day.

There are 46 more mystery cases with an unknown source.

Of the 3141 active cases in Victoria, 449 are healthcare workers, 45 are in disability settings comprising of 31 staff and 14 residents, and 1362 in aged care.

187 are in regional Victoria, which the Premier praised.

"That's a much better position than few weeks ago when regional Victoria had 500-plus cases, I want to thank regional Victoria for following the rules," he said.

"Of the three communities where we thought we had a real challenge, Geelong now has 65 cases, just two new on yesterday, and Bendigo has 15 cases and there are six in Ballarat.

"That's a testament to the amazing work every single Victorian has been doing come forward to get tested, it's made a massive difference."

Chief Health Officer Brett Sutton said Victoria was trending in the right direction.

"We're not below 100 yet but we expect to be this weekend or next week," he said.

"At the moment we are doing the right thing in terms of the things that work to drive transmission down, there's no question we are doing it tough but there's also no question numbers are continuing to decrease in regional Victoria and meto Melbourne. We are at half the level of active cases were a couple of weeks ago.

"The number of people in ICU and hospital remain pretty stable and are slowly decreasing.

"There are fewer aged care outbreaks but still driving a significant proportion of our daily numbers and we know we still have active cases in healthcare workers.

"We are trending in the right direction but do need to hold the course."
