"We have never battled anything like this in the history of humanity."
That's the sobering message from Wimmera-raised health and biosecurity expert Dr Rob Grenfell, who's on the frontline of the fight against COVID-19.
He envisions rollercoaster surges in cases for months to come, social distancing to become the new normal and holds doubts about large events and community sport returning anytime soon.

Since the pandemic began, Dr Grenfell - the director of health of biosecurity business at CSIRO - has led a team of around 50 scientists working to develop potential vaccines.
Though his team has celebrated breakthroughs, the former Natimuk GP was pragmatic about the situation Australia finds itself in.
Dr Grenfell explained in depth the state of play, the steps towards normality and more bluntly, the need to self-isolate.
