Premier Daniel Andrews has agreed to hand over his phone records to the hotel quarantine inquiry, as he extends Victoria's state of emergency.
The inquiry into the botched hotel quarantine program has formally requested the records as it attempts to solve the mystery of who made the fateful decision to use private security guards.
The inquiry has heard security guards were partly responsible for spreading the virus into the community, sparking the state's devastating second wave.
Mr Andrews said the board had asked him and his senior staff, including media personnel, to provide text and phone call logs from March 27.
In texts from that day, former Victoria Police Chief Commissioner Graham Ashton described the appointment of private security as a "deal set up" by the Department of Premier and Cabinet ahead of a key meeting at the state control centre.
"Mr Ashton has indicated he received a phone call," Mr Andrews told reporters on Sunday.
"Out of an abundance of caution, we're happy to look at texts regardless of carrier or service.
"I didn't contact him, he didn't contact me. He indicated that someone did contact him."
The premier said every record sought by the board, headed by retired judge Jennifer Coate, would be provided once Telstra forwarded the information.
"All of us want answers. All of us are entitled to answers," Mr Andrews said.
Victoria's state of emergency and state of disaster have been extended to 11.59pm on November 8.
"There will be a time where we do not need to extend these things and I look forward to that day," the premier said.
He conceded the second wave was "stubborn" as Victoria recorded 12 new cases in the 24 hours to Sunday morning - it's fourth straight day with double-digit infections.
It marginally dropped Melbourne's rolling 14-day case average to 9.3, with the figure at 0.4 for regional areas.
Cases with an unknown source for 14 days as of Thursday were 10.
Authorities had wanted the two-week rolling daily case average to fall to five, with less than five mystery cases, for the city's lockdowns to ease in line with regional Victoria.
One further death - a woman in her 80s linked to aged care - ended the state's three-day stretch without a fatality.
It took Victoria's virus death toll to 810 and the national figure to 898.
Mr Andrews again flagged Melbourne won't be ready to take a "full step" to eased restrictions on October 19, but hinted outdoor activities were likely to pepper rule amendments.
"It will be the stuff that people are really missing," he said.
Victoria's Chief Health Officer Brett Sutton said the Box Hill Hospital outbreak had grown to 12, with a patient and household contact testing positive.
The Chadstone Shopping Centre cluster also recorded one new case, taking its total linked infections to 33.
Prof Sutton said new family outbreaks accounted for eight cases alone on Sunday.
One outbreak in the city's west has infected five people, while another - across two households - has led to three cases.
Meanwhile, the Victorian government has announced new quarantine and business safety measures.
Close contacts who refuse a COVID-19 test on day 11 of quarantine will be forced to spend another 10 days in isolation.
Regional Victorian businesses will also have to take all reasonable steps to ensure patrons aren't from Melbourne before seating them or face a $9913 fine.
It follows a Melbourne man illegally dining at a Kilmore cafe, sparking a fresh outbreak in Mitchell Shire.
Both rule changes come into effect from 11.59pm on Sunday.
