"I'm determined to find a COVID normal which is still a few weeks away.

He said he would not be resigning.
"I don't run from problems and challenges."
"We are in the cooling off of the second wave of a global pandemic, we are on the edge of a significant statement from the premier that will be made tomorrow," Minister Foley said.
"I would like to acknowledge effort of the Victorian community, who have driven the numbers down faster than the roadmap forecasted.
